Capacitor technical knowledge, principles and fundamentals
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 [...]
Safety capacitor refers to a safety capacitors that will not cause electric shock after the capacitor fails and does not endanger personal safety. Safety capacitors are usually only used for [...]
Starting capacitor refer to AC electrolytic capacitors or polypropylene and polyester capacitors used to start single-phase asynchronous motors. The function and working principle of the starting capacitor in the washing [...]
1. Disadvantages of electrolytic capacitors Because of its large capacity and low price, it is widely used in rectifier and filter circuits. The heating of electrolytic capacitors can accelerate [...]
