The filter capacitor plays a role in filtering the alternating current mixed with DC.DC-LINK film capacitors are generally not easy to break down. Although they seem to have no direct connection with IGBT, they actually have a great impact.1. The noise causes the IGBT to run at high load, which incr

Film capacitors are a type of capacitor that are widely used in electronic products. Film capacitors usually use metal foil as electrodes and are wound with plastic film materials such as polyethylene and polypropylene to form a cylindrical structure.In daily work, film capacitors store electrical e

Many people feel that film capacitors should be very quiet when working, or even feel that there should be no sound at all. In fact, this is not the case. In some application scenarios, film capacitors may make obvious sounds when working.Why does the film capacitor make a sound when it is working?T

Recently, I received some common questions about capacitors from Mr. Liu from a certain company. The following is the Q&A between me and the customer.You can also refer to it to increase your knowledge of capacitors.Mr. Liu asked: Film capacitors are subjected to wave soldering and lead-free solderi

Characteristics of metallized film capacitorsFirst, aluminum electrolytic capacitors have a low rated voltage (usually ≤450V). To obtain a higher withstand voltage rating, they usually need to be used in series, and the voltage balancing problem must be considered during the series connection proces

1. The slitting process is to slit the semi-finished film into finished film. Semi-finished metallized film requires equipment slitting machine.2. The winding process rolls the finished film into a core. The core is the most basic and important component of the film capacitor. The core rod needs to

Oxidation of metallized film capacitors results in the formation of an oxide film on the surface. This oxide film is usually insulating and has a lower conductivity than the metal itself.Therefore, when oxidation occurs on the surface of a metallized film capacitor, this oxide film increases the sur

The issue of thin film capacitors impregnated with wax is relatively obscure. I believe many people are not clear about it. The editor happened to encounter a customer who asked this question and discussed it carefully before understanding it. I hope this article can give you some experience and kno

Capacitor film vacuum gauge is a vacuum gauge that measures absolute pressure and total pressure. Its principle is that the pressure change applied to the capacitor film produces a change in the distance between the diaphragms, that is, a change in capacitance. The capacitance change is then convert

If we classify film capacitors according to their internal structure, we can divide them into winding structure and stacked structure. If you have not seen the production process of film capacitors, it is probably difficult to imagine what the difference is between them.The wound type is a structure
