Ceramic capacitor is a ceramic material used as a medium, coated with a layer of metal film on the ceramic surface, and then after high temperature sintering as a capacitor made of electrodes. Ceramic capacitors are mostly used as loop capacitors and pad capacitors for high-stability oscillation cir

The polarity of the electrolytic capacitor can be measured by the resistance barrier of the multimeter.We know that the leakage current of the electrolytic capacitor is small (the leakage resistance is large) when the positive electrode of the electrolytic capacitor is positive (the black pen in the

First of all, we need to understand the characteristics of electrolytic capacitor, before we know why the main board, graphics card, and almost all computer equipment used in electrolytic capacitors: Electrolytic capacitors feature 1: the capacitance per unit volume is very large, tens to hundreds o

In military electronic products, in order to ensure the reliability of the whole machine system, the following principles shall be followed when selecting electrolytic capacitors:(1) to select as many components as possible to be included in the QPLs of military electronic components; (2) to select

The bolted aluminum electrolytic capacitor has a clear positive and negative grade mark on the casing. The positive pole is represented by "+" and the negative electrode "-". Most bolted capacitors are engraved with "+" and "-" signs next to the terminals on the cover plate.
