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 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.
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.
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.
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.
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 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.
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.
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.
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.
Introduction to PIC Microcontroller: Architecture, Features, and Applications08 April 2025
The world's smallest microcontrollers that can be programmed to execute a wide variety of tasks are PIC (Programmable Device Controllers) microcontrollers. In several electronic gadgets, such as phones, machine control systems, warning systems, embedded systems, etc., these microcontrollers are included. There are various types of microcontrollers, even though the best are found in the programmable microcontroller range of GENIE. This microcontrollers are programmed and simulated with software from a circuit wizard.
