Detailed explanation of the basic knowledge of mica capacitors 1

Mica capacitor is an EP4SE230F35I4N capacitor that uses natural or synthetic mica as the dielectric material. Mica is a highly stable and non aging material, therefore, capacitors made from it have excellent electrical performance, including low loss, high precision and stability, as well as excellent high-frequency characteristics. This article will comprehensively introduce the basic knowledge of mica capacitors, including their structure, working principle, classification, applications, and factors affecting their performance.diode

1. Structure and working principle of mica capacitors

Mica capacitors are composed of several thin layers of mica sheets and metal sheets stacked together. The metal sheets serve as electrodes, while the mica sheets act as dielectric materials. This structure is tightly stacked together and then encapsulated in a protective shell. When a voltage is applied across the two ends of the capacitor, the mica layer between the electrodes stores charges, achieving the capacitive effect.diode

2. Classification of Mica Capacitors

Mica capacitors can be classified according to various types of mica, manufacturing processes, and shell materials. According to the type of mica, it can be classified into natural mica capacitors and synthetic mica capacitors. According to the manufacturing process classification, it can be divided into silver paste coated mica capacitors and metal foil mica capacitors. In addition, based on the shell material, mica capacitors can also be divided into plastic encapsulated mica capacitors and metal encapsulated mica capacitors.diode
