Identification and detection of triode in electronic components

Date:2021-05-11 17:08:11

Triode, the full name should be semiconductor triode, also known as bipolar transistor and crystal triode. It is a semiconductor device for controlling current. Its function is to amplify weak signals into electrical signals with large amplitude value. It is also used as a contactless switch. Triode is one of the basic components of semiconductor. It has the function of current amplification and is the core component of electronic circuit. View >>

Identification and detection of electronic components - crystal oscillator!

Date:2021-05-11 16:41:32

Crystal oscillator is widely used in electronic equipment and intelligent control system. Each single-chip microcomputer system has a crystal oscillator. The whole process is called a crystal oscillator. In the single-chip microcomputer system, the crystal oscillator plays a very important role. It combines the internal circuit of the single-chip microcomputer to generate the necessary clock frequency of the single-chip microcomputer. The execution of all instructions of the single-chip microcomputer is based on this. The higher the clock frequency provided by the crystal oscillator, the faster the running speed of the single-chip microcomputer. View >>

Experience sharing of electronic component testing: how to judge the quality of various diodes

Date:2021-05-11 14:06:26

Diode faults are mainly manifested in open circuit, short circuit and unstable voltage stabilization. Among the three faults, the former one shows the increase of power supply voltage; The latter fault shows that the power supply voltage becomes low to zero volts or the output is unstable. How to check and judge the diode? Below, Chuangxin online testing organization will share the testing experience of electronic components. Let's have a look! View >>

Collection essential | experience sharing of common electronic component testing methods

Date:2021-05-10 18:03:42

A large number of various types of electronic components are used in electronic equipment. The failure of electrical equipment is mostly caused by the damage of components. The failure of electronic equipment caused by other reasons often leads to the damage of electronic components, resulting in the failure of equipment. Therefore, the detection of components is an essential basic work. How to accurately and effectively detect the relevant parameters of components and judge whether the components are normal is not a stereotype. Different methods must be adopted according to different components to judge whether the components are normal or not. The following is the experience sharing of common electronic component testing methods for your reference. View >>

What has the IC supply chain become? An original price adjustment letter was revealed

Date:2021-05-07 15:36:00

In the second quarter, chip shortage and price rise continued. In April, many chip manufacturers at home and abroad successively sent letters to raise prices and suspend orders. At the same time, wafer foundry also began a new round of price increases. Various signs show that the shortage of chips and the rise in prices are bound to reach a new height. The market in the "post epidemic era" is destined to be extraordinary. View >>

Inspection process and standard of "must see" electronic components (attached figure)

Date:2021-04-29 16:53:46

Electronic components are the smallest units of electronic circuits, among which resistance, capacitance, inductance, diode and triode are common components of electronic circuits. In the circuit, they are the objects that need to be detected and replaced in maintenance. Therefore, this paper briefly introduces the testing process and standards of electronic components.

The quality of the inductor can be detected with a multimeter. As shown in the figure, place the multimeter in "R" × 1 "gear, the two probes (regardless of positive and negative) are connected with the two pins of the inductor, the indication of the probe should be close to" 0 Ω ", and the inductor with large inductance should have a certain resistance value. If the needle does not move, it indicates that the inductor is internally open; If the indication of the gauge needle is unstable, it indicates poor internal contact. View >>
