If we classify film capacitors according to their internal structure, we can divide them into winding structure and laminated structure. If you have not seen the production process of film capacitors, it is probably difficult to imagine what the difference is inside them. Today, we will use detailed

Nowadays, with the development of science and technology, many electronic products have been updated from old versions to the present. While increasing functions, we also need to find ways to reduce the size of electronic products. These electronic products are composed of different electronic compo

In the era of rapid development of modern electronic technology, film capacitors have occupied an important position in the field of electronics with their unique working performance. Although the public may not be as familiar with film capacitors as some consumer electronic products, film capacitor

1. Environmental resistance ability test2.1 Temperature shock testThe temperature shock test is to determine the capacitor's ability to be exposed to high and low temperature extremes and to resist the alternating shock of high and low temperature extremes through the rapid change of ambient tempera

The development of science and technology has driven the progress of the times and also produced electronic components and electronic equipment. Electronic components are indispensable parts of electronic equipment, and many functions of electronic equipment also rely on electronic components.In add

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
