Manifold Absolute Pressure (MAP) Sensor: Working Principles, Structure, and Types31 March 2025
Manifold Absolute Pressure Sensor, referred to as MAP sensor. The MAP sensor is an indirect air flow meter, and its signal is one of the important signals for the basic fuel injection control of the engine.
SMD Resistors: Codes, Size, Testing, Tolerance and Selection23 October 2025
SMD Resistor or Chip Fixed Resistor is one of the metal glass glaze resistors. It is a resistor made by mixing metal powder and glass glaze powder and printing on the substrate by the screen printing method. It is resistant to humidity and high temperature and has a low-temperature coefficient. SMD Resistor can greatly save the cost of circuit space and make the design more refined.
Proximity Sensors: Types, Working Principles and Applications22 April 2022
Hello everyone, I am Rose. Welcome to the new post today. Today I will introduce proximity sensors to you. This article introduce its definition, types, working principles, selection and detection as well as some common trouble shooting of it.
H-bridge: Working, Circuits and Applications03 December 2021
The H-bridge is a typical DC motor control circuit, named after its resemblance to the letter H. The four triodes form the four vertical legs of the H, and the motor is the horizontal bar in the H.
Photoresistor Basics: Types, Principles and Applications16 October 2025
The article introduces the photoresistor’s main characteristics and principles including the working principle and structural principle. There are three types of photoresistor: ultraviolet photoresistors, infrared photoresistors, visible light photoresistors. Dimming circuit and light switch are the two applications of the photoresistor.
Switching Diodes Basics: Working, Types and Circuit Analysis24 October 2025
Switching Diodes are a type of semiconductor diode. They are specially designed and manufactured for "on" and "off" on a circuit. As the name suggests, it refers to a diode with a switching function.
What is Feedthrough Capacitor?06 November 2021
Hello, everyone. I am Rose. Today I will introduce the feedthrough capacitor to you. The feedthrough capacitor is a three-terminal capacitor that is used to reduce high frequencies. The feedthrough capacitor, unlike regular three-terminal capacitors, is directly installed on the metal panel, resulting in a lower grounding inductance and a negligible effect on the lead inductance.
What is GND in a Circuit?08 December 2021
In this article, you will learn the classification of GND and its working principle. GND is an abbreviation for the ground. GND represents the ground wire or the 0 wire. This ground is not a real ground, it is a ground assumed for the purpose of application. For the power supply, it is the negative pole of a power supply.
Understanding of Coaxial Cable06 August 2021
Coaxial cable is a broadband transmission line with low loss and high isolation characteristics. This blog introduces the classification, structure, working principle, parameters, and characteristics of coaxial cables.
Structure and Working Principle of Field Effect Transistors07 April 2025
A field-effect transistor is a semiconductor device that uses the electric field effect of the control input circuit to control the output circuit current and is named after it. Because it only depends on the majority carrier in the semiconductor to conduct electricity, it is also called the unipolar transistor. FET English is Field Effect Transistor, abbreviated as FET. There are two main types: junction FET (JFET) and metal-oxide-semiconductor FET (MOSFET).
Inverter Introduction: Structures, Working Principles and Features18 February 2022
Hello everyone, I am Rose. Today I will introduce inverter to you. The inverter is a converter that converts DC power (battery, storage battery) into constant frequency and constant voltage or frequency modulation and voltage regulation AC power (usually 220V, 50Hz sine wave).
What is ISP (Image Signal Processor)?15 September 2021
The ISP (Image Signal Processor) is mainly responsible for the photographing part in the system-on-chip (SOC) of the mobile phone.
