Photocoupler Basis: Description, Applications and Working Principle29 September 2021
Hello, everyone. I am Rose. Welcome back to the new post today. Photocoupler is also known as optocoupler. To communicate electrical impulses, optocouplers employ light as a channel. It is frequently utilized in many circuits because it provides an excellent isolation effect on input and output electrical signals. After reading this article, you will have a clear understanding of Photocoupler.
Random Access Memory: Definition, Types and Working29 August 2020
Random Access Memory (RAM), also called main memory, is an internal memory that directly exchanges data with the CPU. It can read and write at any time (except when refreshing), and and is usually used as a temporary data storage medium for the operating system or other running programs. The biggest difference between it and ROM is the volatility of data, that is, the stored data of RAM will be lost once the power is off.
Automatic Voltage Regulator: Ultimate Guide to Stable Power and Equipment Protection06 May 2025
This in-depth manual will explore the realm of automatic voltage regulators. We'll go over what they are, how they work, their important advantages, and factors to take into account while selecting one. By the conclusion, you'll see why an AVR is essential to modern operations and living, not simply a nice-to-have.
Metal Oxide Varistor: Specifications, Working and Construction26 January 2021
MOV is essentially a variable resistor, but MOVs can adjust its resistance depending on the applied voltage, unlike potentiometers. If the voltage through it raises the resistance decreases and vice versa. This property is helpful in shielding the circuits from high voltage surges, so they are often used in an electrical network as surge protectors.
SAW Filter: Introduction, Features and Applications30 December 2020
The Surface Acoustic Wave (SAW) filter is a passive band-pass filter made by using the piezoelectric effect and the physical characteristics of surface acoustic wave propagation. Its role is to filter and delay electrical signals. It has the advantages of small size, stable performance, strong overload capacity, low phase distortion, and no need to adjust, so it is used in televisions, video recorders, wireless data transmission systems and other fields.

In recent years, China has become the world's largest semiconductor market, consuming a large number of semiconductor chips every year. Driven by market applications and with the support of the National Semiconductor Fund, China's semiconductor industry has achieved rapid development, and a number of representative semiconductor IC design companies have gradually emerged. Let's take a look at the current top ten IC design companies in China.
Electronic components in a smart watch15 May 2023
One of the consumer goods categories with the greatest rate of growth is wearables, which heavily rely on electronics miniaturization. Customers are becoming more and more reliant on smartphones and smartwatches that have a wide range of services, including those that measure their daily steps, display health metrics, schedule appointments, send emails, and more.
A Guide to Semiconductor IP Core18 January 2022
The IP to be introduced in this article is both a technical term and a commodity. It brings together the wisdom of chip designers and has the attributes of a commodity and intellectual property, which can be promoted, sold, and applied. Therefore, there are scientific and commercial activities such as IP development, IP trading and IP reuse in the semiconductor industry, and there are also some companies that are named as IP vendors and IP providers.
What is a Fiber Optic Sensor?31 October 2025
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.
Introduction to Temperature Sensors24 October 2025
The temperature sensor refers to a sensor that can sense the temperature and convert it into a usable output signal, which is the core part of the temperature measuring instrument. It's divided into 5 types and each type has unique working principles. Besides, some factors need to be noticed in the installation and using process. For the temperature sensor can accurately measure the ambient temperature, it's widely used in various fields and provide convenience for people's production and daily lives.
What are the Types of Audio Cables?27 October 2021
Today, I will introduce you to some common audio cables. I hope you will have a new understanding of the cable of the audio equipment.
Introduction to Types of Motion Sensors24 October 2025
Motion sensor refers to a device that detects the motion of an object or person, including gravity, linear acceleration, rotation vector, vibration frequency, etc. Motion sensors can be used to monitor device movements such as tilt, shake, rotation, or swing. Among them, the rotation vector sensor and the gravity sensor are the most commonly used sensors for motion detection and monitoring. Today we come to learn about various types of motion sensors, including accelerometers, tilt sensors, vibration sensors, PIR (passive infrared) sensors, and rotation sensors.
