The cathode of the SMD Electrolytic capacitor is made of electrolyte, which is also a widely used capacitor. Polarized Electrolytic capacitor usually plays the role of power filter, decoupling, signal coupling, time constant setting and DC isolation in the power circuit or intermediate frequency and low-frequency circu……

Safety capacitors include two types: X capacitors and Y capacitors. X capacitors are capacitors that are connected across two power lines (L-N) and generally use metal film capacitors; Y-capacitors are capacitors that span between two power lines and the ground (L-E, N-E), usually appearing in pairs. Firstly, we know t……

The Aluminum electrolytic capacitor is of bipolar structure, and the polarity shall be paid attention to during installation. Reverse installation is not allowed. The application of AC or reverse voltage may cause short circuit or damage to the capacitor. The DC voltage loaded onto the capacitor terminal should not exc……

In addition, direct contact between the extended cathode aluminum foil and the capacitor aluminum shell is also a good way to reduce thermal resistance. At the same time, it should be noted that the aluminum shell will carry negative electricity and cannot be used as a negative electrode connection. The capacitor must ……

1. Design considerations include the use of an anodic aluminum foil oxide layer as the dielectric in the capacitor of a non solid electrolyte. The electrolyte s……

Electrolytic capacitor are widely used in different fields of power electronics, mainly for smoothing, energy storage or filtering after AC voltage rectification, and also for non precision timing delay. In the MTBF prediction of switching power supply, the model analysis results show that Electrolytic capacitor is the……

First of all, make it clear that the aluminum Electrolytic capacitor will be broken. It is only a matter of time. There are many reasons that affect the lifespan of capacitors, such as overvoltage, reverse voltage, high temperature, rapid charging and discharging, etc. Under normal use, the biggest impact is temperatur……

Ceramic capacitor is a kind of capacitor with small positive capacitance temperature coefficient, which is used in high stability oscillation circuit as circuit capacitor and padding capacitor. Low frequency ceramic capacitors are limited to being used as bypass or DC isolation in circuits with lower operating frequenc……
