VRLA Battery: Working Principle, Capacity and Maintenance12 March 2021
VRLA batteries, which means Valve Regulated Lead Acid Battery was born in the 1970s. By 1975, a considerable scale of production had been formed in some developed countries, and industrialization was soon formed and put on the market in large quantities. Although this battery is also a lead-acid battery, it has many advantages compared with the original lead-acid battery, and is very popular with users, especially for those who need to install battery supporting equipment together (or a workshop). , Such as UPS, telecommunications equipment, mobile communication equipment, computers, motorcycles, etc.
AC Contactor: What is Self-Locking?01 March 2022
AC contactors often use three arc extinguishing methods: double-break electric arc extinguishing, longitudinal seam arc extinguishing and grid arc extinguishing. It is used to eliminate the arc generated by the moving and static contacts during the opening and closing process.This article mainly introduce the principle of AC Contactor self-locking.
What is Universal Serial Bus (USB)?28 May 2021
Universal Serial Bus (USB) is a serial bus standard and a technical specification for input and output interfaces. It is widely used in information communication devices. The latest generation is USB4, and its transmission speed is 40Gbit/s, the three-stage voltage is 5V/12V/20V, the maximum power supply is 100W.
What is a Fiber Optic Sensor?23 July 2020
Fiber optic sensor is a sensor that converts the state of the measured object into a measurable optical signal. The fiber optic sensor is to send the light beam incident from the light source to the modulator through the optical fiber, and interact with the external measured parameters in the modulator so that the optical properties of the light such as light intensity, wavelength, frequency, phase, polarization state, etc. will be changed.
What is Visible Light Communication(VLC)?13 October 2021
In some situations, visible light communication (VLC) has considerable advantages over the more generally utilized radio frequency (RF). VLC has gained a lot of attention because of its ability to provide a very accurate and safe indoor positioning system, in addition to the obvious usage of data transmission from one location to another. Implementing a VLC system poses unique hurdles in terms of system integration and power management, particularly for people unfamiliar with the technology. This article will look at some of the uses of VLC, as well as the fundamentals of the VLC positioning system, and how the most recent devices offer a low-risk design approach.
Introduction to Flyback Transformer29 January 2021
As an energy conversion device that transfers energy from one part of the circuit to the other part at constant power, a flyback transformer can be described. Based on the application, the voltage is stepped up to a very high value in a flyback transformer. It is also called a transformer for line output, as the voltage of the output line is fed to the other part of the circuit. The primary winding of the transformer can be powered by a DC circuit with the assistance of the rectifying circuit.
Introduction to BAW Filter25 September 2021
BAW filters are low-cost, small RF filters that can be utilized in a variety of applications up to 6 GHz.
Characteristics, Types, and Functions of Electrolytic Capacitors04 March 2020
Inside the electrolytic capacitor is an electrolyte material that stores electric charge. It has positive and negative polarity, which is similar to a battery, and it cannot be reversed. The positive electrode is a metal substrate with an oxide film. The negative electrode is connected to the electrolyte (solid and non-solid) through the metal electrode plate.
Tunnel Diode: Definition, Features and Tunneling Process25 August 2020
Tunnel diode, also known as Ezaki diode, is a crystal diode with tunnel effect current as the main current component. The tunnel diode is a semiconductor diode made of a mixture of gallium arsenide (GaAs) and gallium antimonide (GaSb).
Toggle Switches: Features, Types and Applications23 January 2021
Toggle switch adopts integrated circuit technology and SMT appearance device technology to manufacture a new generation of photoelectric switch devices. It has intelligent functions such as delay, expansion, external synchronization, anti-interference, high reliability, stable working area, and self-diagnosis.

What is an Inverting Amplifier?25 April 2025
An inverting amplifier is a fundamental configuration of operational amplifiers where the output signal has opposite polarity to the input signal. This configuration uses an operational amplifier with its inverting input terminal receiving the input signal, while the non-inverting terminal is typically connected to ground. The primary function of this circuit is to amplify the input signal while inverting its phase by 180 degrees.
What are Graphene Transistors?24 March 2020
Graphene is a two-dimensional crystal. Its structure is very stable because carbon atoms are arranged in hexagons and connected to each other to form a carbon molecule.
