Near Field Communication (NFC) Explained: Working and Applications24 May 2021
Near Field Communication (NFC) is evolved from the integration of non-contact radio frequency identification (RFID) and interconnection technology. Devices using NFC technology can exchange data when they are close to each other. By integrating the functions of inductive card readers, inductive cards, and point-to-point communication on a single chip, applications such as mobile payment, e-ticketing, access control, mobile identification, and anti-counterfeiting can be realized by using mobile terminals.
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.
Graphics Card Explained: Classification, Working and Structure27 May 2021
A Graphics card (Video card, Display card, Video adapter) is one of the basic components of personal computers. It converts the display information required by the computer system to drive the display, which is an important component that connects the monitor and the PC motherboard, and is one of the important equipment of "human-machine". Its built-in parallel computing capability is also used for deep learning and other operations.
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'.
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.
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.
How to Design Reliable High-Side Switching Circuits with P-Channel MOSFETs?22 July 2025
This article provides a comprehensive guide to designing reliable high-side switching circuits using P-channel MOSFETs, drawing from a real-world failure case shared by a Reddit user. The main issue identified was that the user's 48V system damaged the MOSFET because the gate-source voltage exceeded the device's ±20V limit (reaching -48V), and the article offers complete solutions including proper MOSFET parameter selection, using Zener diodes to clamp gate voltage, optimizing driver circuit resistor values for faster switching, and adding flyback diodes for inductive load protection, serving as a practical design roadmap for beginners in power switching applications.
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.
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.
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.
What is LCD? Working Principle, Features, and Future Trends05 January 2026
LCD is a liquid crystal display. The LCD structure is to place a liquid crystal cell between two parallel glass substrates. LCD has replaced CRT as the mainstream, and the price has dropped a lot, and it has become fully popular.
