What are the characteristics of ceramic capacitors?

As a kind of electronic components, ceramic capacitors have long appeared in various electronic products and are widely used.

What is a ceramic capacitor?

The ceramic capacitor is a capacitor formed by using a ceramic material as a medium, coating a metal film on the surface of the ceramic, and then sintering it at a high temperature as an electrode. It is commonly used in high-stability oscillation circuits. As a circuit, bypass capacitor, and pad capacitor, it is divided into variable capacitors with adjustable capacity and fixed capacitors with fixed capacity.

The ceramic capacitors are divided into high frequency ceramic capacitors and low frequency ceramic capacitors according to frequency. The high-frequency ceramic capacitor has small volume, high stability, good high-frequency characteristics, low loss (tgδ<0.01015), high dielectric strength, simple structure, and can also be used as capacitors with different temperature characteristics. High-frequency ceramic capacitors are mainly used in high-frequency circuits and high-frequency high-voltage circuits in electronic equipment. The low-frequency ceramic capacitor has the advantages of small volume and large capacity, but has poor stability and large loss angle, and is mainly used for low-frequency bypass, DC blocking, and filtering circuits.
