What is an ASIC Chip?07 January 2026
ASIC (Application Specific Integrated Circuit) is a special-purpose integrated circuit, which is an integrated circuit designed and manufactured in response to specific user requirements and the needs of a specific electronic system.
Basic Introduction to Metal Film Resistor28 August 2020
Metal film resistors are a kind of film resistors. Metal film resistors are resistors in which special metals or alloys are used as resistor materials, and the resistor film layer is basically formed on ceramic or glass by vacuum evaporation or sputtering.
Introduction to TVS Diodes07 August 2020
TVS diodes (Transient voltage suppression diodes), also called clamp diodes, are electronic parts for protection, which can protect electrical equipment from voltage spikes introduced by wires. It is a high-performance circuit protection device commonly used internationally.
Diode Basis: Symbol, Types and Applications09 January 2026
Hello everyone, I am Rose. Today I will introduce diode to you. A diode is an electronic device made of semiconductor materials (silicon, selenium, germanium, etc.). It has unidirectional conductivity, that is, when a forward voltage is applied to the anode and cathode of the diode, the diode conducts. When a reverse voltage is applied to the anode and cathode, the diode is turned off.
Strain Gauges: Structure, Working Principle and Common Types16 December 2020
Strain gauge is a device that changes resistance with force; it converts physical quantities such as force, pressure, tension, and weight into changes in resistance to measure these physical quantities. When an external force acts on a fixed object, stress and strain are generated. The reaction force (external force) generated inside the object is the stress, and the displacement and deformation generated are the strain.
Image Sensor: How do CCD and CMOS Sensors work?24 October 2025
An image sensor is a semiconductor device that can convert optical images into digital signals. It is widely used in digital cameras and other electronic optical devices. The image sensor uses the photoelectric conversion function of the photoelectric device to convert the light image on the photosensitive surface into an electrical signal in a proportional relationship with the light image. There are two kinds of image sensors which are CMOS and CCD. CCD and CMOS have their advantages in different application scenarios.
Ceramic Capacitor Failure Mode and Mechanism Analysis21 May 2022
Hello, this is Candy. A ceramic capacitor is a fixed-value capacitor in which the dielectric is made of ceramic material. It's made up of two or more alternating ceramic layers and a metal electrode layer. The electrical behavior and thus applications of ceramic material are determined by its composition. But when it comes to ceramic capacitors failing, what is the cause of this phenomenon? What's the pattern? This article will introduce you in detail.
Basic Introduction to Color Sensor07 January 2026
The color sensor is also called a color recognition sensor. It is a sensor that compares the object color with the previously taught reference color to detect the color.
General PCB Layout Design Guidelines for RF and Digital-to-Analog Circuits20 January 2022
This article provides guidance and advice on radio frequency (RF) printed circuit board (PCB) design and layout, including some discussion of mixed-signal applications such as digital, analog, and RF components on the same PCB. The content is organized by topic to provide "best practice" guidelines that should be applied in conjunction with all other design and manufacturing guidelines that may apply to specific components, PCB manufacturers, and materials.
Introduction to Inductive Reactance16 April 2021
Alternating current can also pass through the coil, but the inductance of the coil has an obstructive effect on the alternating current. This obstruction is called inductive reactance.
RTD Sensors: Working Principle, Features and Applications22 May 2025
The term RTD stands for Temperature Detector for Resistance. This sensor is also known as a thermometer for resistance. To calculate the temperature, this sensor is used. They are typically available as a piece of fine wire made of nickel or copper platinum, wound around a heart of ceramic or glass. To calculate the temperature, this sensor makes use of the wire's temperature/resistance relationship.
EMI Filter: Introduction, Functions and Applications23 December 2020
Electromagnetic interference filter, also known as "EMI filter" is an electronic circuit device used to suppress electromagnetic interference, especially noise in power lines or control signal lines. The EMI filter functions as two low-pass filters: one is to attenuate common mode interference, and the other is to attenuate differential mode interference. It is top choice for electronic equipment design engineers to control conducted electromagnetic interference and radiated electromagnetic interference.
