Introduction to buck, boost, and buck-boost converters28 September 2021
A buck converter (buck converter) is a DC-to-DC power converter that lowers the voltage from the source to the load (in drawing a smaller average current).A boost converter or a DC boost chopper is another name for a DC boost converter. A buck-boost converter is a DC-DC converter with an output voltage that can be higher or lower than the input voltage. This article mainly introduces these three converters and their working principles.
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.
Thermistor: Characteristics, Classification, Symbol and Applications10 December 2025
Thermistors are a class of sensitive components. They are divided into positive temperature coefficient thermistors (PTC) and negative temperature coefficient thermistors (NTC) according to different temperature coefficients.
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.
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).
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 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.

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.
