The difference between ceramic capacitor and high frequency ceramic capacitor

It seems to the public that ceramic capacitors and high frequency dielectric capacitors are two kinds of capacitors that are very similar. In fact, it is different from the fact that the ceramic capacitor and the high frequency ceramic capacitor are different. High frequency ceramic capacitor is a kind of ceramic high capacitor.

Ceramic capacitors are made of ceramic (barium titanate) with high dielectric constant (barium titanate) to be extruded into a circular tube, a wafer or a disc as a medium, and silver plating is made of silver on a ceramic as an electrode. It is also divided into two kinds of high frequency ceramic and low frequency ceramic.

Ceramic capacitors have small positive capacitance temperature coefficient capacitors. They are used in high stability oscillating circuits as loop capacitors and pad capacitors.

Low frequency ceramic capacitors are limited to bypass or DC use in low working frequency circuits, or not high requirements for stability and loss (including high frequency). Such capacitors are not suitable for use in pulse circuits because they are susceptible to breakdown by pulse voltage.

The high frequency ceramic capacitor is sprayed into thin film by a special mixture suitable for spraying, and the medium is sintered into a "single stone" structure with silver electrode. High frequency ceramic capacitors are suitable for high frequency circuit mica capacitors. In terms of structure, it can be divided into chaff and silver. The silver electrode is made directly on the mica film by vacuum evaporation or plating on the silver layer. Due to the elimination of air gap, the temperature coefficient is greatly reduced and the stability of capacitance is higher than that of chaff.

High frequency ceramic capacitor has good frequency characteristics, high Q value, low temperature coefficient, can not be made of large capacity; it is widely used in high frequency electrical apparatus and can be used as a standard capacitor glass glaze capacitor. The performance is comparable to that of mica capacitor. It can withstand all kinds of climatic conditions. It can work at 200 500V or higher, and the rated working voltage can reach up to.

With the development of science and technology, ceramic capacitors and high frequency dielectric capacitors have been widely used. The selection of good quality, safe ceramic capacitors and high frequency ceramic capacitors is also very important. For example, ceramic capacitors, high frequency ceramic capacitors, low frequency ceramic capacitors, JEC safety capacitors.

The problem of capacitor safety is one of the complex, realistic, and serious non-traditional security problems facing manufacturing enterprises. It seems to the public that ceramic capacitors and high frequency dielectric capacitors are two kinds of capacitors which are very similar. In fact, it is different from the ceramic capacitors and high frequency dielectric containers. A kind of ceramic high capacitor.
