What should we pay attention to when using electrolytic capacitors
2024-01-30
Aluminum electrolytic capacitor has larger capacitor, larger series resistance, larger inductance and temperature sensitivity. It is suitable for the occasion of little temperature change and low working frequency (not higher than 25kHz), and can be used for low frequency filtering (parallel filtering effect of electro……
What is the error range of electrolytic capacitor?
2024-01-12
Electrolytic capacitors with letters on the level of accuracy can be compared below.
Expressed by letter: D - 005 - ± 0.5%; F - 01 - ± 1%; G - 02 - ± 2%; J - I - ± 5%; K - - Class II - ± 10%; M - Class III - ± 20%.
The accuracy level of a commonly used capacitor (that is, the error range) is the same as that of a……
What is the function of capacitors?
2024-01-06
In a DC circuit, the capacitor is equivalent to an open circuit. A capacitor is a component that can store electric charge and is one of the most commonly used electronic components. This has to start with the structure of the capacitor. A simpler capacitor is made up of plates at both ends and an insulating dielectric……
Why can't electrolytic capacitors be reversed?

1. Polar electrolytic capacitor: The positive electrode is a metal substrate to which an oxide film is adhered, and the negative electrode is connected to the electrolyte through a metal plate. Polar electrolytic capacitors usually function as power supply filtering, decoupling, signal coupling and time constant settin……
How do electrolytic capacitors distinguish positive and negative poles?
2023-11-21
The method for judging the positive and negative electrodes of electrolytic capacitors is as follows:
[Appearance discrimination]: First, take out an electrolytic capacitor. The first method is to look at the electrolytic capacitor hose. The end of the hose is printed with the negative electrode mark. The other end ……
