Basic knowledge of electronic components

For practitioners in electronic components, it is very necessary to understand some basic knowledge of electronic components. If you don't even know the basics of electronic components, how do you work in this industry? For those who know nothing about the basics of electronic components, just read this article and Konnra Electroncis engineers will give you the basics of electronic components and let you understand its classification. And cognition.

Konnra Electroncis engineers pointed out that electronic components are part of electronic components and small machines and instruments. They are often composed of several parts and can be used in similar products. They are often referred to as parts of the electrical, radio, instrumentation and other industries. The actual electronic components are the general term for components and devices.

I. Components: The factory is processing a product that does not change the molecular composition. The product can be called a component, and does not require an energy/power supply device.

It includes: resistors, capacitors, inductors. (also known as Passive Components)
(1) Circuit type devices: diodes, resistors, etc.
(2) Connection devices: connectors, sockets, connecting cables, printed circuit boards (PCBs)
II.The device: the device that changes the molecular structure of the factory during production and processing is called device
The device is divided into active devices and discrete devices.
1. Active device, its main features are:
(1) Self-consumption of electrical energy
(2) An external power source is required.
2. Discrete devices, divided into:
(1) Bipolar crystal triode
(2) Field effect transistor
(3) SCR
(4) Semiconductor resistance and capacitance
3. Analog integrated circuits mainly refer to integrated circuits composed of analog circuits composed of capacitors, resistors, transistors, etc., which are integrated to process analog signals. There are many analog integrated circuits, such as integrated operational amplifiers, comparators, logarithmic and exponential amplifiers, analog multipliers, phase-locked loops, and power management chips. The main constituent circuits of analog integrated circuits are: amplifiers, filters, feedback circuits, reference source circuits, switched capacitor circuits, and the like. The analog integrated circuit design is mainly obtained by manual circuit debugging and simulation by experienced designers. The corresponding digital integrated circuit design is automatically generated by using the hardware description language under the control of EDA software.
4. Digital integrated circuits are digital logic circuits or systems made by integrating components and wiring on a unified semiconductor chip. Digital integrated circuits can be classified into small-scale integrated (SSI) circuits, medium-scale integrated MSI circuits, large-scale integrated (LSI) circuits, and very large-scale integrated VLSI circuits, depending on the number of gates or elements and devices included in the digital integrated circuit. Very large scale integration (ULSI) circuits.
Small-scale integrated circuits contain less than 10 gates, or no more than 100 components
Medium-scale integrated circuits contain between 10 and 100 gates, or between 100 and 1000 components.
Large-scale integrated circuits contain more than 100 gates, or between 10 and 10 components.
Very large scale integrated circuits contain more than 10,000 gates, or the number of components is between 10 and 10.

The number of components of a very large scale integrated circuit is between 10 and 10. It includes: basic logic gates, flip-flops, registers, decoders, drivers, counters, shaping circuits, programmable logic devices, microprocessors, microcontrollers, DSPs, and more.
