Zener diodes play a crucial role in various electronic circuits as voltage stabilizers and regulators, ensuring stable power supply and protecting sensitive components. As with any electronic component, correctly identifying the positive and negative poles of a Zener diode is paramount for proper function. The following article provides several methods to help you distinguish between the anode and cathode of a Zener diode.

1. Visual Inspection: Manufacturers often mark the diode's exterior with indicators to assist users in identifying the positive and negative poles. Common identifiers include ink markings, etchings, or indentations on the diode's casing. In some cases, the anode (positive) end might be marked with red ink, while the cathode (negative) end might be marked with black ink.

2. Pin Length: For certain types of Zener diodes, the pin length of the positive and negative poles might vary. Generally, the anode (positive) pin is longer, and the cathode (negative) pin is shorter. However, keep in mind that this rule is not always accurate, especially for used or repurposed components.

3. Multimeter Testing: A digital multimeter can provide a definitive method to distinguish between the anode and cathode of a Zener diode. Set the multimeter to diode testing mode. Connect the red (positive) probe to the suspected anode and the black (negative) probe to the suspected cathode. A displayed value greater than zero and within a typical diode voltage drop range (e.g., 0.5V to 0.8V) indicates that the probes are correctly connected to the anode and cathode.

With these techniques, you can effectively identify the positive and negative poles of a Zener diode. Ensuring the correct polarity during installation is essential for maintaining a stable, well-performing circuit. When working with electronic components, always adhere to safety guidelines to minimize the risk of electric shocks or potential component damage.

Classification and Identification of Common Electronic Components

Classification and identification of common electronic components

Electronic components are electronic components and small components of machines and instruments, which themselves often consist of a number of parts and can be commonly used in the same kind of products. It often refers to certain parts of the electrical, radio and instrumentation industries, such as capacitors, transistors, touring wire and clockwork and other sub-devices under the general term, commonly known as diodes.

In layman's terms, the basic parts used for manufacturing or assembling electronic machines can be called components, and components are independent individuals in electronic circuits.

Active and passive components

Active components are components that can perform active functions such as amplification of electrical signals, oscillation, control of current or energy distribution, and even perform data operations and processing when supplied with energy. Active components include various types of transistors, integrated circuits, video tubes, and displays.

Passive components, as opposed to active components, are those that cannot be excited and amplified, oscillate, etc., and respond to electrical signals passively and submissively, with the electrical signals passing through the electronic components according to their original basic characteristics. The most common resistors, capacitors, inductors, etc. are passive components.

Active and passive components

Active components correspond to active components. If an electronic component works with a power source present inside it, this device is called an active component and requires energy to achieve its specific function. Active devices also consume electrical energy themselves, and high-power active devices are usually equipped with heat sinks.

Passive components are the counterpart of passive components. Resistors, capacitors and inductors are called passive components because they do not require an external excitation power supply to perform their functions when a signal is passed through the circuit. Passive devices consume very little electrical energy themselves, or convert electrical energy into other forms of energy.

Discrete Components and Integrated Circuits

In terms of physical structure, circuit function and engineering parameters, active devices can be divided into two categories: discrete components and integrated circuits. Discrete components are the opposite of integrated circuits.

Integrated circuit (ic, integrated circuit) is a kind of circuit required in a class of transistors, resistance, capacitance and other components and wiring interconnected together, made in a small piece or several small pieces of semiconductor wafers or dielectric substrates, packaged as a whole, with the circuit function of electronic components.

Discrete components are ordinary resistors, capacitors and transistors and other individual electronic components, collectively referred to as discrete components. Discrete components are single-function, "minimum" components, no longer have other components inside the functional unit.

Distinguish between circuit components and connected components

Passive components in electronic systems can be divided into circuit-like components and connection-like components according to the circuit function they perform.

Identification of common electronic components

I. Resistors

Resistors, which we are used to calling resistors, are one of the most commonly used electronic components in electronic devices. Resistor in the circuit with "r" plus the number, such as: r13 said the number of 13 resistors. The main role of resistors in the circuit is shunt, current limiting, voltage divider, bias, filtering (used in combination with capacitors) and impedance matching.

Parameter identification: The unit of resistance is ohm (ω), and the multiplier units are: kilo-ohm (kω), megohm (mω), etc. The conversion method is: 1 megohm (mω) = 1000 kilohm (kω) = 1000000 ohms

There are three methods of labeling the parameters of resistance, namely, the direct labeling method, the color-coded method and the number labeling method.

1, the number of labeling method is mainly used for SMD and other small volume of the circuit, such as: 472 said 47 × 100ω that 4.7k; 103 said 10000ω (10 followed by three 0) is 10kω

2, the color ring labeling method is most used, the first color ring indicates the maximum resistance of a number, the second color ring indicates the second number, the third color ring indicates the resistance of the end should have several zeroes and the fourth color ring indicates the error of resistance.

The relationship between the color coding position and multiplicity of resistance is shown in the following table.

2. capacitor

Capacitor is a component composed of two metal films close together and separated by an insulating material in the middle. Capacitance is generally expressed by "c" plus a number in the circuit, such as c223, which means the capacitor number is 223. The main characteristic of capacitor is to isolate the direct current.

There are also two main parameters of capacitors: nominal capacity and allowable error.

1, nominal capacitance, refers to the capacitance marked on the capacitor, the size of capacitance capacity is to indicate the size of electrical energy can be stored. The capacitor's impedance to the AC signal is called capacitive resistance, which is related to the frequency and capacity of the AC signal.

Capacitive reactance xc=1/2πfc

(f indicates the frequency of AC signal, c indicates the capacitance)

Identification method: The identification method of capacitance is basically the same as that of resistance, which is also divided into three methods: direct scale method, color scale method and number scale method. The basic unit of capacitance is expressed by farad (f), other units are: millifarad (mf), microfarad (uf), nanofarad (nf), picofarad (pf), where 1 farad = 103 mf = 106 microfarad = 109 nanofarad = 1012 picofarad.

Direct marking method: The capacitance value of capacitor with large capacity is marked directly on the capacitor, such as 2200 uf/10v.

Letter representation method: 152m=1500pf.

Digital representation method: Generally three digits are used to indicate the capacity size, the first two digits indicate the effective number, and the third digit is the multiplier. Such as: 102 said 10 × 102pf = 1000pf.

2, the allowable error is divided into three levels, and the resistor error is expressed in the same way. Trimmer capacitors and variable capacitors are marked with the minimum and maximum value of its capacity, such as 7/270p

3. inductance

The inductance coil is made of insulated wire in an insulated skeleton around a certain number of turns. DC can be passed through the coil, DC resistance is the resistance of the wire itself, the voltage drop is very small; when the AC signal through the coil, the coil ends will produce self-inductance electromotive force. The direction of the self-induced electromotive force is opposite to the direction of the applied voltage, preventing the passage of AC, so the characteristics of the inductor is through DC resistance AC, the higher the frequency, the greater the coil impedance. The higher the frequency, the higher the coil impedance. Inductors can be used in circuits with capacitors to form oscillating circuits.

The inductor in the circuit is often indicated by "l" plus a number, such as: l3 indicates the inductor number 3.

Inductance generally has a direct scale method and color-coded method, color-coded method and resistance similar. The basic unit of inductance is: Hen (h), conversion units are: 1h = 103mh = 106uh.

4. the crystal diode

Diode's main characteristic is one-way conductivity, that is, in the role of forward voltage, on resistance is very small; and in the role of reverse voltage, on resistance is very large or infinity. Crystal diodes are used to detect radio waves in radios, to convert AC into pulsating DC in power conversion circuits, to act as non-contact switches in digital circuits, etc., all using its one-way conductivity.

Crystal diodes can be divided into: rectifier diodes, isolation diodes, Schottky diodes, light-emitting diodes and voltage regulator diodes, etc. according to their role.

1, identification method.

Diode identification is very simple, the n-pole of the low-power diode (negative), most of the diode exterior using a color circle marked out, some diodes also use the diode special symbol to indicate the p-pole (positive) or n-pole (negative), there are also symbols used to mark the "p", "n " to determine the polarity of the diode. Light-emitting diode positive and negative can be identified from the pin length, long feet for positive, short feet for negative.

2, the main parameters

Rated forward working current, refers to the maximum value of forward current allowed through the diode when working continuously for a long time. Because the current through the tube will make the core heat, temperature rise, the temperature exceeds the permissible limit (about 140 for silicon tubes, germanium tubes for about 90), it will make the core overheat and damage.

The maximum reverse working voltage, the reverse voltage added to both ends of the diode to a certain value, the tube will be broken through, the loss of one-way conductivity. In order to ensure the safety of use, the maximum reverse working voltage value is specified.

Reverse current, refers to the diode in the role of the specified temperature and the highest reverse voltage, the reverse current flowing through the diode. The smaller the reverse current, the better the unidirectional conductivity of the tube. It is worth noting that the reverse current has a close relationship with the temperature, about 10 per increase in temperature, the reverse current doubled.

5. Crystal transistors

Crystal transistor in the circuit with amplification and switching role. We use crystal transistors in the circuit to amplify the weak signal current or made automatic switch to control the on/off of household appliances. Crystal transistors in the circuit is often expressed by "q" plus a number, such as: q1 means the number of 1 transistor.

Commonly used crystal transistor package form of metal package and plastic package two categories, the pin arrangement has a certain pattern. Crystal transistor's three poles, respectively, called the base (b), collector (c) and emitter (e), the emitter on the arrow indicates the direction of current flow through the transistor.

6. integrated circuits

Integrated circuits are diodes, transistors and resistors and capacitors and other components in accordance with the requirements of the circuit structure, made on a small piece of semiconductor material to form a complete circuit with certain functions, and then encapsulated, its literal symbol is IC.

Integrated circuits were developed rapidly in the late 1960s with the development of electronics technology. Integrated circuits and the use of discrete components assembled circuits, with fewer components, light weight, small size, good performance and power saving and many other advantages, so the integration of electronic products has become an inevitable trend in the development of electronic technology.

Prepare your supply chain

Buyers of electronic components must now be prepared for future prices, extended delivery time, and continuous challenge of the supply chain. Looking forward to the future, if the price and delivery time continues to increase, the procurement of JIT may become increasingly inevitable. On the contrary, buyers may need to adopt the "just in case" business model, holding excess inventory and finished products to prevent the long -term preparation period and the supply chain interruption.

As the shortage and the interruption of the supply chain continue, communication with customers and suppliers will be essential. Regular communication with suppliers will help buyers prepare for extension of delivery time, and always understand the changing market conditions at any time. Regular communication with customers will help customers manage the expectations of potential delays, rising prices and increased delivery time. This is essential to ease the impact of this news or at least ensure that customers will not be taken attention to the sudden changes in this chaotic market.

Most importantly, buyers of electronic components must take measures to expand and improve their supplier network. In this era, managing your supply chain requires every link to work as a cohesive unit. The distributor of the agent rather than a partner cannot withstand the storm of this market.

can a mime die in host? if so what happens?

Yes they can. They are susceptible to almost all of the things their host would have been, were they still alive.

If they die in host, they die as a mime. It's the trade off for experiencing life. Their influence stays within the body, and the body remains pale and color coded, unlike when they leave their dead host & the body's natural colors return.

Typically though, mimes will expell themselves from a host that they cannot save/is no longer viable. As long as they leave a fatally wounded host before it dies, they will be okay.

I need to educate myself further on the depths of early tech advancements and video art, but eventually I'd love to make a video essay about how it connects to electric dreams because I truly believe that in a way it's a love letter to the rising genre of video art and electronic sound art present in the movie's time period. I know it I just need more context to make proper connections.
