Compared with batteries and traditional physical capacitors, the characteristics of features of super capacitorsare mainly reflected in: (1) High power density. It can reach 102～104 kW/kg, which is much higher [...]
Film capacitors use metal foil as electrodes, and are divided into Mylar capacitors, PP, and PS capacitors. How to detect the quality of film capacitors? How to detect the quality [...]
Steps to explain the use of film capacitors Film capacitors use organic film as the medium. When they exceed the rated voltage and rated current, flames may occur and the [...]
In appearance, the difference between monolithic capacitors and ceramic capacitors is: monolithic capacitor are actually ceramic chip capacitor sintered after welding the leads, generally square, while ceramic capacitor are chip-shaped, [...]
AC capacitors are also called non-polarized capacitors. From the literal meaning, it can be seen that they can be polarized. How to test an AC capacitor? 1. Multimeter detection method [...]
Electrolytic capacitors may fail due to excessive discharge or depletion of electrolyte and failure to charge. The following is the method to judge the quality of the capacitor: 1. Multimeter [...]
Combines the advantages of solid-state and electrolytic capacitor Electrolytic capacitor (abbreviated as E-cap) has the characteristics of large capacity and low price, and is widely used by various electronic [...]
Monolithic capacitor is another name for multilayer ceramic capacitor. The English name is monolithic ceramic capacitor or mulTI-layer ceramic capacitor, or MLCC for short, which is widely used in electronic [...]
The Y capacitance is a capacitor that is connected between the two lines of the power line and the ground (L-E, N-E), usually in pairs. Due to the limitation of [...]
