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.
Introduction to Centrifugal Switch27 January 2021
On the theory of centrifugal power, a centrifugal switch operates. It's just an electric switch. These switches are specially designed for induction motors in single and split phases. As its operation is identical to that of a centrifugal clutch used in vehicles, the centrifugal switch is generally known as 'clutch'.
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 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.
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.
High Voltage Capacitor Safety: The Ultimate Guide10 August 2026
Have you ever wondered about the silent powerhouses behind our modern electrical grids and advanced electronic devices? High voltage capacitors are precisely that – critical components capable of storing immense electrical charges, essential for everything from industrial power supplies to medical imaging equipment. But with great power comes great responsibility, and the handling of these components demands a profound understanding of safety. Ignoring proper procedures can lead to severe consequences, including electric shock, burns, or even explosions. In this ultimate guide, we’ll delve deep into the world of high voltage capacitors, exploring their types, applications, and, most importantly, the comprehensive safety protocols required for their safe handling, testing, and storage. We’ll cover everything from safe discharge methods to essential personal protective equipment, ensuring you’re equipped with the knowledge to work confidently and securely with these powerful devices.
What are Avalanche Diodes?02 April 2020
Avalanche diodes are semiconductor devices that use the avalanche multiplication effect and carrier transit time effect in the PN junctions to generate microwave oscillations. If a large reverse voltage is applied across the diode, the space charge region is widened from the N + P junction to the IP + junction. The electric field in the entire space charge region is the largest at N + P. If the electric field intensity exceeds the breakdown electric field in a small area near the N + P junction, then this phenomenon is called avalanche breakdown and the area where it occurs is the avalanche region.
What is GDDR?25 November 2021
GDDR SDRAM is one of the key core components of a graphics card, and its strength and capacity will directly affect the final performance of the card.
Ultimate Guide to KVM Switches: Definition, Usage, and 2025 Trends18 December 2025
Hello, I am Rose. Welcome back to the new post today. KVM stands for keyboard, video and mouse. The so-called KVM is also called a multi-computer controller, and the official name is a multi-computer switch. A KVM switch is a hardware device that allows users to control 2, 4, 8, 16, or even more than 4096 computer hosts through a set of keyboards, video monitors, and mice.
