Talk to everyone today about the breakdown of electronic components
1. Component refers to the product that does not change the molecular structure of the raw material during production and processing by the processing plant. It contains: resistors, capacitors, inductors. (Also called PassiveComponents)
The components are divided into:
1. Circuit components: diodes, varistors, etc.
2. Connecting components: RF connectors, power sockets, connecting cables, packaging printed circuit boards (PCB)
2. The device refers to the product that the processing plant has changed the molecular formula of the raw material during production and manufacturing is called a device
The devices are divided into:
1. Active device, its main features are: (1) It consumes electromagnetic energy (2) It must be an external switching power supply.
2. The company's discrete devices are divided into (1) double optically active transistors (2) field effect transistors (3) thyristors (4) semiconductor material resistors and capacitors
The resistor is represented by "R" plus a number in the circuit, such as: R1 represents a resistor with serial number 1. The key functions of the resistor in the circuit are: separation, overcurrent protection, voltage divider circuit, reference point, etc.
Capacitors are generally represented by "C" plus a number in the circuit (for example, C13 expresses a capacitor with serial number 13). The capacitor is a component composed of two ceramic membranes that are closely attached and separated by an insulating layer material in the middle. The characteristics of the capacitor are mainly Communicate and communicate through direct commodity circulation.
The volumetric size of a capacitor expresses the size of electromagnetic energy that can be stored. The blocking effect of the capacitor on communicating AC data signals is called capacitive reactance, which is related to the frequency and capacitance of communicating AC data signals.
Crystal diodes are often represented by "D" plus a number in the circuit, such as: D5 represents a diode with a serial number of 5.
Efficacy: The key feature of the diode is the unilateral conductivity, that is, the on-off resistor is not large under the action of the forward voltage; and the on-off resistor is huge or infinite under the effect of the reverse working voltage.
Because the diode has the above-mentioned characteristics, it is often used in circuits such as rectifiers, protections, voltage regulator tubes, optical rotation maintenance, number control, radio broadcast deployment, and noise suppression in cordless phones.
Although not many applications of inductors in electronic production, they are equally critical in circuits. People think that inductors, like capacitors, are also a kind of energy storage technology components, which can change electromagnetic energy into magnetic field energy and store kinetic energy in the electromagnetic field. The inductance is expressed by the mark L, its component is Bert (H), and millihenry (mH) is commonly used for enterprises. It often works with capacitors to form LC filters and LC oscillators. In addition, we also used the characteristics of inductors to produce choke coils, transformers, and automotive relays.
Make up the circuit
An integrated circuit is a device with a certain effect produced by using a unique processing technology to integrate triodes, resistors, capacitors and other components on a silicon substrate. It is abbreviated as IC in English and also aliased as integrated ic.
Simulated analog integrated circuit refers to a simulated analog integrated circuit that is integrated with capacitors, resistors, triodes and other components to solve digital signals. There are many simulation analog integrated circuits, such as integrated operational amplifier circuit, comparator, majority and exponential amplifier, simulation analog multiplier (divider), phase locked loop, power management integrated IC, etc. The key components of the simulation analog integrated circuit are: amplifier, filter, feedback circuit, standard source circuit, power switch capacitor circuit, etc. The simulation analog integrated circuit design plan is mainly obtained by manual circuit adjustment and simulation based on the interior designer with work experience. The corresponding large digital integrated circuit design plan is based on the application hardware configuration description language. Under the control of EDA mobile phone software, it is fully automatic and comprehensive.
Large digital integrated circuits are digital logic circuits or system software made by integrating components and wires on the same integrated circuit chip. According to the total number of gate circuits or components and devices included in the large digital integrated circuit, the large digital integrated circuit can be divided into small-scale taxpayer integrated (SSI) circuits, medium-scale integrated (MSI) circuits, large-scale integrated (LSI) circuits, Integrated circuit technology integrates VLSI circuits and special-scale integrated ULSI circuits. Small-scale taxpayer integrated circuits include less than 10 gates, or the number of components does not exceed 100; medium-scale business-scale integrated circuits include between 10 and 100 gates, or the number of components is 100- 1000 middle; large-scale integrated circuits include more than 100 gates, or the number of components is between 10-10; integrated circuit technology integrated circuits include more than 10,000 gates, or the number of components In the middle of 10-10; the number of components of special-scale integrated circuits is in the middle of 10-10. It includes: basic logic gates, trigger principles, registers, decoders, controllers, electronic counters, plastic and cosmetic circuits, programmable logic devices, microcontrollers, microcontroller design, DSP, etc.
