What is Potentiometer?25 October 2021
Hello, I am Rose. Welcome back to the new post today. The potentiometer is a type of electromechanical component that can be found in a variety of instruments and electronic devices. A potentiometer is a resistance that can be adjusted and changed, and it is an electronic component that can be modified. This article mainly introduces structure, classification, electrical parameters and model name and type of potentiometer.
The Introduction to QFN Package15 October 2025
Hello everyone, I am Rose. Today I will introduce QFN Package to you. QFN (Quad Flat No-leads Package), one of the surface-mount packages.QFN package does not have any extension pins at all.
What is a Fiber Optic Connector?27 October 2025
Fiber optic connector is a detachable (movable) device between optical fibers. It precisely connects the two end faces of the optical fiber so that the optical energy output by the transmitting fiber can be coupled to the receiving fiber to the maximum extent.
What is SMT (Surface Mount Technology)?02 December 2021
SMT (Surface Mount Technology) refers to the abbreviation of a series of technological processes that are processed on the basis of PCB. SMT is the most popular technology and process in the electronic assembly industry.
The Era of Business Globalization: Chinese Founders Aim to Conquer the World30 May 2022
Today, there is hardly a Chinese company that does not aspire to be a global company.
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.
What is Instrument Transformer?08 January 2022
Current transformers and voltage transformers are both referred to as instrument transformers. In this article, I will tell you what is instrument transformer and how many types are there.
What is an Encoder?20 October 2020
An encoder is a device that compiles and converts a signal (such as a bitstream) or data into a signal form that can be used for communication, transmission, and storage. The encoder converts angular displacement or linear displacement into electrical signals.
IOT-Based Anti-theft Handbag29 August 2023
Hello everyone, welcome to the new post today. We will discuss all the security features of our Anti-theft handbag in this post.
What is a Schmitt Trigger?09 December 2021
Schmitt triggers have two stable states, but unlike general triggers, Schmitt triggers use a potential trigger mode, and their state is maintained by the input signal potential. Schmitt triggers have different threshold voltages for input signals with two different changing directions, negatively decreasing and positively increasing.
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.
