1) First look at the appearance. If there is a problem with the appearance, the film capacitor is likely to have a problem.2) Use the resistance range of a multimeter to test the two pins of the film electrode, which should show a very high resistance. If you have a capacitance meter, measure the ca

Metallized film capacitors use polyester or polypropylene film as the dielectric, with zinc-aluminum alloy deposited onto the film surface via vacuum evaporation to form electrodes. These capacitors are formed by non-inductive, stepless winding or lamination. Metallized film capacitors offer high wi

Film capacitors use metal foil as electrodes, overlapping it with plastic films such as polyethylene, polypropylene, polystyrene or polycarbonate at both ends and then winding it into a cylindrical structure.Theoretically, the production costs of film capacitors of the same model and size will vary,

The development prospects of film capacitors are promising, especially in recent years, as the number of people using film capacitors has continued to increase online. Why do film capacitors win such high praise? It is inseparable from their advantages. This article will tell you about the nine adva

Due to the limitations of materials and production technology, the film capacitors we currently produce cannot achieve zero error. The actual capacity of the film capacitors produced will have some errors. Theoretically, the smaller the capacity error, the better. How is the accuracy of film capacit

Parameters to consider when selecting film capacitors1. Capacity valueCapacitance refers to the amount of charge a film capacitor can store. It's usually expressed in farads (F) or picofarads (pF). When selecting a film capacitor, you need to determine the appropriate capacitance based on the circui

Capacitors are common electronic components, and a wide variety of capacitors are available on the market for different applications. To enhance understanding of capacitors, this article will explain the compatibility of electrolytic and film capacitors.In an electrical appliance, especially in a CD

Polypropylene film capacitors are what we often call CBB capacitors. Anyone who has used electrolytic capacitors knows that they can explode during use for various reasons. Can polypropylene film capacitors explode? What precautions should be taken when using them?Polypropylene film capacitors may a

The emergence of electronic products has brought a lot of help and entertainment to our work and life. For example, mobile phones can make and receive calls, video calls, and shop online, which are inseparable from the various electronic components and circuits that assemble electronic products.In e

CBB capacitors and CL capacitors are two different types of film capacitors. While they are similar in some ways, there are also some differences. Below is a detailed explanation of CBB capacitors and CL capacitors, as well as the main differences between them.First, let's take a look at CBB capacit
