Semiconductor, wafer, lithography, chip, integrated circuit concept application

Start with semiconductors, which are substances whose conductivity is between conductors (metals) and insulators (stones), including silicon and germanium. Because silicon has large gaps that can be doped with impurities, it can be used to manufacture important semiconductor electronic components—transistors. The main functions of transistors are to amplify signals and switch. Transistors are like radios for data signals. The principle of radio is to amplify weak signals. , released from the speaker, and the transistor can amplify the current of the signal, allowing the current to pass through in a specific way.

Understand the role of inductors and the functions and uses of inductors

Inductors are devices used to provide inductance, and various coils wound with insulated wires are called inductances. Its main function is to block AC and DC, block high frequency and pass low frequency, that is to say, high frequency signal will encounter great resistance when passing through the inductor coil, and it is difficult to pass, while the resistance presented by low frequency signal passing through it is relatively Small, that is, low-frequency signals can pass through it more easily. The resistance of the inductive coil to direct current is almost zero.

Low-inductance custom power resistors for energy technology

Centralized power generation technology is undergoing a revolution. Traditional power plants such as coal, gas and nuclear power plants are gradually being replaced by renewable, decentralized solutions such as wind, solar or biomass power plants. The latter type of power plants generally follow the same principle, that is to use renewable energy sources (solar, wind and biomass) and generate DC or AC voltage or current through one or more conversion processes. Since energy producers are decentralized, more and more electricity is no longer fed into high-voltage power systems, but into medium-voltage and low-voltage power systems. Therefore, in the future, there will be an increasing need for intelligent power system management using energy storage devices to meet peak load demands in a variable manner. The core components of these power plants are power converters capable of supplying the generated electrical energy to the power system or consumers in a synchronized manner and of suitable quality. Not only do these power plants place extreme demands on the individual components, but they also have to achieve a service life of around 20 years under harsh environmental conditions.

Are the characteristics and characteristics of chip inductors the same?

In the vast world of electronic components, many of us are so overwhelmed by the sheer number of products available that we don't know which ones correspond to which ones and which ones can be produced directly. Even if we do, we don't know how to tell them apart, what's the difference between these objects, how can we tell them apart, what are the similarities between them? what's the difference?

How to choose a chip transistor

Selection of SMD transistors There are several major problems in SMD triode applications: The first is to use through-hole assembled triodes in the past, how to find the corresponding chip triodes; The second is the triode model found on the parametric circuit that cannot be purchased in the market, and how to replace it. This is often a big problem for designers, developers and maintenance personnel in the application.
