Voltage Regulator: Types, Working, and Applications23 February 2021
A voltage regulator is a part of the power supply device that, under all operating conditions, ensures a stable, continuous voltage supply. During power changes and differences in loads, it controls voltage. As well as DC voltages, it will control AC. We will take a closer look at the idea of a voltage regulator and the different forms in this blog, and we will expand on the common voltage regulator ICs and their common implementations!
How to read Resistors Color Code?16 October 2025
We can read the resistance value according to the resistors color code because of the use of four color bands or five color bands or six color bands on the resistors to indicate the resistance value. The color information representing the resistance value can be read at once from any angle.
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.
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).
