What is an Electromagnetic Relay?13 October 2020
Electromagnetic relay is an electronic control device. It has a control system (also called an input loop) and a controlled system (also called an output loop). It is usually used in automatic control circuits. It actually a kind of "automatic switch" that uses a smaller current and a lower current to control a larger current and a higher voltage. Therefore, it plays the role of automatic adjustment, safety protection, and conversion circuit in the circuit.
What is a Force Sensor?19 April 2021
Force sensor (force sensor) is a component that converts the magnitude of force into related electrical signals. The force sensor can detect mechanical quantities such as tension, pressure, weight, torque, strain, and interior stress. It has become indispensable core component of power equipment, engineering machinery, various working machines, and industrial automation systems.
Circuit Breaker: Working Principle, Types and Structure21 November 2025
Circuit breaker is a switching device capable of closing, carrying and breaking the current under normal and abnormal circuit conditions within a specified time. So what's its structure and how many types are there? How does it work? Read this.
What is VCSEL?28 October 2021
Hello everyone, I am Rose. I welcome you on board, today I will introduce VCSEL to you. The Vertical-Cavity Surface-Emitting Laser (VCSEL, or Vertical-Cavity Surface-Emitting Laser) is a semiconductor whose laser is emitted perpendicular to the top surface. It differs from an edge-fired laser, which emits the laser from the edge.
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.
The Difference and Application of SPI, UART, I2C Communication15 October 2025
Hello everyone, I am Rose. Welcome to the new post today. Communication between electronic devices is like communication between humans. Both parties need to speak the same language. In electronic products, these languages are called communication protocols. This article will make some comparisons between SPI, UART, and I2C.
Shift Register: Classification and Working Principle26 December 2020
The shift register is a sequential logic circuit that can be used to store or transmit data in the form of binary numbers. It loads the input data and then moves or "shifts" it to its output every clock cycle, so it is called a shift register.
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.
What is DDR5 SDRAM? The Ultimate Guide to Specs, Architecture, and Market Trends05 January 2026
DDR5 is a computer memory specification. In July 2020, the JEDEC Association officially announced the DDR5 standard, starting at 4800MHz and reaching 6400MHz in the future.
What is a Server CPU?22 December 2021
This article introduces the classification of server CPUs, their advantages and disadvantages, and the differences between them and desktop CPUs.
LDO VS DC to DC Converter11 March 2022
Hello everyone, I am Rose. Today I will introduce the differences between LDO and DC to DC Converter to you. LDO stands for low dropout regulator, which is a low dropout linear regulator.A DC/DC converter is a voltage converter that converts an input voltage and efficiently outputs a fixed voltage.
What Is An Intrinsic Semiconductor?03 November 2020
An intrinsic semiconductor is a single crystal made from a pure semiconductor through a certain process. Intrinsic semiconductors are semiconductors with complete crystal lattices without any impurities. Its conductivity is not affected by any impurities or lattice defects, and is only determined by the nature of the semiconductor material itself.
