The structure and characteristics of polypropylene film capacitors

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 [...]

bypass capacitors introduction

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 [...]

Chip capacitors and its dielectric material

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 [...]

What is the load capacitance?

The load capacitance refers to the sum of all the effective capacitances inside and outside the IC block connected by the two leads of the crystal oscillator, which can be regarded as the series connection capacitance of the crystal oscillator in the circuit. The different load frequency determines the different oscillation frequency of the oscillator. For [...]
