Polystyrene capacitors belong to the category of organic film capacitors, and their dielectric is polystyrene film, and there are two types of electrodes: metal foil type and metal film type. Since the polystyrene film is a heat-shrinkable oriented film, the wound capacitor can be made into a non-sealed structure by the method of self-heat shrinkage polymerization. [...]

Polypropylene film capacitors belong to the category of organic film capacitors. Its dielectric is polypropylene film. There are two types of electrodes: metal sink type and metal film type. The coiled capacitor core is encapsulated with epoxy resin or packed into plastic and metal casings. In the package. Polypropylene capacitors made with metal film electrodes are [...]

In electronic components, we often consider some products. Is it better to choose a patch or a plug-in electrolytic capacitor? How to choose? How to choose electronic components that are more suitable for us according to the development of the market? Let's talk about the fundamental difference between chip electrolytic capacitors and plug-in electrolytic capacitors. What [...]

The bypass capacitors is a capacitor that can bypass and filter high frequency components in alternating current mixed with high frequency current and low frequency current. The main function of the bypass capacitors is to generate an AC shunt to eliminate unnecessary energy that enters the susceptible area. That is, when the signal mixed with high [...]

The stability and capacity accuracy of chip capacitors correspond to the dielectric materials they use, and they are mainly divided into three categories: 1. It is a high-frequency capacitor with COG/NPO as the Class I medium. Its temperature coefficient is ±30ppm/℃, and its capacitance is very stable. It hardly changes with temperature, voltage and time. It [...]
