LVDT - Linear Variable Differential Transformer Basics16 January 2021
LVDT is the abbreviation of linear variable differential transformer, which belongs to linear displacement sensor. It is a movable iron core transformer that consists of a primary coil, two secondary coils, iron core, coil frame, shell and other components.
Infrared Thermometer: How it Works? How to Use it?12 August 2021
Infrared thermometers are divided into fixed thermometers and hand-held thermometers. They are a kind of thermometer that detects the amount of infrared rays on the surface of an object to achieve temperature measurement.
Introduction to Step-down Transformers14 October 2020
The step-down transformer is a transformer that converts the higher voltage at the input terminal into an ideal low voltage output, so as to achieve the purpose of step-down. The step-down transformer is a very important equipment in the power transmission and transformation system. Its normal operation not only relates to its own safety and reliable power supply for users, but also directly affects the stability of the power system...
Introduction to MD8002A Audio Amplifier27 March 2025
The MD8002A is an audio power amplifier that uses a 5V DC power supply to provide 2.0 watts of continuous power to a BTL load with less than 10% distortion. It was created with the aim of providing high-quality o/p control with fewer components. It doesn't use any output coupling capacitors or bootstrap capacitors.

The Reason for the Leakage Current of MOS Tube26 March 2022
Hello everyone, I am Rose. Welcome to the new post today. This article describes 6 causes of MOSFET leakage current.
Introduction to Silicon Controlled Rectifier25 September 2020
Silicon Controlled Rectifier, abbreviated as SCR, is a high-power electrical component, also known as a thyristor. It has the advantages of small size, high efficiency and long life. In the automatic control system, it can be used as a high-power drive device to realize the control of high-power equipment with low-power controls. It has been widely used in AC and DC motor speed control system, power control system and servo system.
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.
What is a Reed Relay?16 April 2021
A reed relay is a type of relay that uses an electromagnet to act directly on the reed-like contact of a reed switch contained within a glass envelope, typically bringing the reeds together to make contact when the electromagnet is powered.
New Crisis in Semiconductors: Neon Gas Prices Soar 9 Times21 March 2022
According to MoneyDJ, the war between Russia and Ukraine has halted the operations of the Ukrainian industry, which supplies half of the world's neon gas, and the price of neon has soared nearly nine times in China. Neon is a key raw material for chip manufacturing, which has cast a shadow over the global semiconductor supply.
Facial Recognition: Features, Working and Applications02 September 2021
The broad sense of facial recognition includes a series of technologies for building a facial recognition system, including face image acquisition, face positioning, facial recognition preprocessing, identity confirmation, and identity search, etc… The narrow sense of facial recognition refers specifically to the adoption of the system for confirming or finding the identity of a human face.
Introduction to Optical Zoom and Digital Zoom19 June 2021
Optical zoom relies on the structure of the optical lens to achieve zoom, that is, the lens of the camera is moved to zoom in and out of the scene to be shot, and the resolution and image quality will not change. The greater the optical zoom factor, the more distant objects can be captured. Digital zoom uses the processor in the digital camera to increase the area of each pixel in the picture to achieve the purpose of magnification.
