Rectifier Diode: Function and Circuit12 August 2020
Rectifier Diode is a semiconductor device used to convert alternating current to direct current.It has obvious unidirectional conductivity, and can be made of materials such as semiconductor germanium or silicon. This article gives you a brief introduction to rectifier diodes.
What is SERDES?04 November 2021
The abbreviation SERDES stands for SERializer/DESerializer in English. It's a point-to-point (P2P) serial communication technique that uses time division multiplexing (TDM). That is, at the transmitting end, multiple low-speed parallel signals are changed into high-speed serial signals, which are then re-converted into low-speed parallel signals at the receiving end via the transmission medium (optical cable or copper wire).
How does a Photodiode Work?15 August 2020
A photodiode is a special diode (light-receiving device) that converts optical signals into electrical signals.It has a pn junction, and its shell has a window with glass for light penetration.So how does it work and how do we use it? Read this article to find the answer.
Understanding of Carbon Film Resistors17 October 2025
A carbon film resistor is a type of film resistor, which is also called thermal decomposition carbon film resistor. It’s a thin-film resistor in which the carbon that is thermally decomposed from a hydrocarbon at high temperatures is deposited on a substrate. It adopts high-temperature vacuum coating technology to tightly attach carbon to the surface of a porcelain rod to form a carbon film, and coats the surface with an epoxy resin to protect the film. Its surface is often coated with green protective paint. The thickness of the carbon film determines the resistance value. And usually, the thickness of the film and the groove are used to control the resistor. Besides, it has a low price, stable performance, a wide range of resistance and power.
Semiconductor Materials:Types, Properties and Production Process21 October 2025
The semiconductor material is a kind of electronic materials with semiconductor properties and can be used to make semiconductor devices and integrated circuits. Various external factors such as light, heat, magnetism, and electricity will act on semiconductors and arouse some physical effects and phenomena, which can be referred to as the semiconductor properties. The majority of the base materials constituting solid-state electronic devices are semiconductors. Different types of semiconductor devices have different functions and characteristics because of the various semiconductor properties.
Will HBM replace DDR and become Computer Memory?09 September 2021
The characteristics of high bandwidth and high latency determine that HBM is very suitable for GPU memory. But for personal computers, the tasks to be processed by the CPU are extremely unpredictable, require various random storage accesses, and are inherently more sensitive to latency. So in the short term, it is difficult for HBM to replace DDR on PCs.
What is a Polypropylene Capacitor?08 November 2021
A polypropylene capacitor is a kind of capacitor with a very stable electric capacity. It is often used in applications requiring very precise capacitance and can replace most polyphenylene or mica capacitors.

Characteristics and Working Principle of IGBT31 October 2025
IGBT, Insulated Gate Bipolar Transistor, is a composite fully controlled voltage-driven power semiconductor device composed of BJT (bipolar transistor) and IGFET, (Insulated Gate Field Effect Transistor). It has the advantages of both the high input impedance of MOSFET and the low on-voltage drop of GTR.
Millimeter Wave Radar: Advantages, Types, and Applications18 October 2021
Millimeter wave radar is a radar that works in millimeter wave. Millimeter waves refer to the 30 ~ 300GHz frequency domain (the wavelength is 1 to 10 mm). The wavelength of millimeter waves is between microwaves and centimeters, so millimeter wave radar has some advantages of microwave radar and photoereta.
