What are Shunts?07 December 2020
A shunt is a measuring element that uses voltage to indicate current. It is made according to the principle of generating voltage at both ends of the resistor when DC current passes through the resistor. It is connected in parallel with the current circuit of measuring instruments to expand its measurement range; or An element on which voltage is measured, thereby indirectly measuring current.

Basic Introduction to Filter Capacitor05 December 2020
The filter capacitor refers to an energy storage device installed at both ends of the rectifier circuit to reduce the ripple coefficient of AC pulsation and improve the efficient and smooth DC output.
What are Memory Chips?03 December 2020
Memory chip is the specific application of the concept of embedded system chip in the memory industry. Therefore, whether it is a system chip or a memory chip, it is through embedding software in a single chip to achieve multi-function and high performance, as well as support for multiple protocols, multiple hardware, and different applications.
What are Comparators?03 December 2020
Comparing two or more data items to determine whether they are equal, or determining the size relationship and arrangement order between them is called comparison. A circuit or device that can realize this comparison function is called a comparator.
Basic Introduction to System on a Chip02 December 2020
System on a chip is generally called SoC, also called system-level chip. It is a product or an integrated circuit with a dedicated target, which contains a complete system and all the contents of embedded software. It is also a technology to realize the whole process from determining the system function to the software/hardware division, and completing the design.
What are TPMS Sensors?21 November 2020
TPMS stands for "Tire Pressure Monitoring System". It is mainly used to automatically monitor tire pressure in real-time when the car is driving, and to alarm tire leaks and low pressure. Each car tire is equipped with a TPMS sensor connected to the tire valve, which regularly measures tire pressure, temperature, and acceleration information and is converted into digital form by the MCU in the TPMS sensor.
How do Solar Cells Work?20 November 2020
Solar cells are devices that directly convert light energy into electrical energy through the photoelectric effect or photochemical effect. Crystalline silicon solar cells that work with the photovoltaic effect are the mainstream, while thin-film cells that work with the photochemical effect are still in their infancy.
DVI Connector: Types, Advantages, Distiguishment And Development18 November 2020
A DVI connector, that is, digital video interface connector, is an interface standard launched in 1999 by the DDWG (Digital Display Working Group) formed by Silicon Image, Intel, Compaq, IBM, HP, NEC, Fujitsu and other companies.
Classification and Working Principle of Ballast Resistor18 November 2020
The ballast resistor is connected between the power source and one or more discharge lamps and is mainly used to limit the current of the lamp to a required value. It may include devices that change the supply voltage or frequency and increase the power factor, which can be used alone or together with the starter to provide the necessary conditions for the lamp to start.
Introduction to PCB Layout Principles13 November 2020
What are the basic principles to be followed in the PCB board layout? How to design a PCB layout with a large number of components? How are electronic components laid out and routed on the circuit board? This article is an explanation of these questions.
Toroidal transformer: Principles, Features, Types and Applications13 November 2020
Toroidal transformer is a type of electronic transformer, which has been widely used in household appliances and other electronic equipment with high technical requirements. It’s mainly used as a power transformer and isolation transformer, also widely used in computers, medical equipment, telecommunications, instruments and lighting. The toroidal transformer is a competitive electronic transformer for its good output characteristics and anti-interference ability.
