元太电子

There are many types of electronic components, and new products are also emerging. Here are some of the most commonly used types of electronic components and their classification methods. Electronic components can be categorized in a number of ways, each with a different focus, as exemplified below.

For example, light-emitting diodes (LEDs) can be classified as diodes, and can be classified as display devices with digital tubes and LCDs.

At the same time, LEDs can also be classified as optoelectronic devices with optocoupler devices. In addition, optocoupler devices can also be classified as transistors with transistors, field effect transistors, and the like. For example, the varistor can be classified as a resistance element or a protection type element.

The classification of components can be determined according to actual needs and actual conditions. It is more realistic to consider the comprehensive factors and consider the key characteristics and applications of the components, production technology, and convenient communication.

1. Fixed resistors, potentials, and sensitive resistors can be collectively referred to as resistors.

2. The resistor of the chip resistor is an oxide film (thick film resistor) or a metal film (thin film resistor), so it can be classified as a film resistor together with the color ring resistor.

3. Thermistors can be classified as sensors (temperature sensors).

4. Varistor, transient suppression diode, recoverable fuse in thermistor PTC, etc., can be classified as a protection component together with the fuse. The protection component can be further divided into a voltage protection component and a current protection component.

5. A varistor made of ceramic material. The ceramic used in the thermistor is a semiconductor ceramic, but these components are generally not classified as semiconductor devices.

6. Chip multilayer ceramic capacitors and plug-in ceramic capacitors can be combined into ceramic capacitors. However, since chip multilayer ceramic capacitors are much more widely used than plug-in ceramic capacitors, they can be classified separately. The ceramic capacitors are presented in a singularity.

7. Switches, relays, connectors, electrodes, etc. can be classified as electromechanical components.

8. Magnetic beads are a special type of inductor that can also be classified as an inductor.

9. The electret type receiver includes a semiconductor device such as a MOS transistor, and the solid state relay includes a semiconductor device such as an optocoupler. A semiconductor device with a crystal oscillator, such as an IC or a crystal, is generally not classified in a semiconductor device when it is classified, but is classified into an electroacoustic device, a relay, and a crystal element.

10. Some micro-motor system components can be classified into sensors.
