High voltage ceramic capacitor has the function of eliminating noise and filtering, and can be used in high voltage environment.
Ceramic capacitor is a kind of capacitor which uses ceramic material as medium, coating a layer of metal film on the surface of ceramic, and then sintered at high temperature as electrode. It is usually used in high stability oscillation circuit as circuit, bypass capacitor and pad capacitor.
The chip capacitor is mainly for high frequency. The high voltage chip capacitor depends on where you use it. The typical function can eliminate high frequency interference. The advantages are as follows:
1. High stability of capacity loss with temperature and frequency
2. The special series structure is suitable for long-term high voltage operation
3. High current climbing rate and suitable for non inductive structure of high current circuit.

Leaded Ceramic disc blue epoxy reigned capacitors are usually designed and manufactured by coating a ceramic disc with silver contacts on both sides.
To achieve larger capacitance, these devices can be made from multiple or times of layers.
Ceramic disc capacitors are usually through-hole mounting components with two leads and has much advantages due to their small size.
Ceramic capacitors are majorly used in the resonant circuit in transmitter stations.
Ceramic disc capacitors are also used across brush DC motors to minimize RF noise.
To understand a capacitor with code‘103’.
As the first two digits are 10 and the 3rd digit is 3, so the multiplier factor is 1000, the total capacitance value in pF is as follows:
10*1000 = 10000 pF
Similarly, if the capacitor code is 132, the 3rd digit is 2 so the multiplier factor is 100. The capacitance value will be calculated as follows:
13*100 = 1300 pF

The WEET WCA high-voltage ceramic chip capacitor is a round chip capacitor with ceramic material as the medium.The shell is ceramic for insulation.
One of the main characteristics of high-voltage ceramic capacitor is that it has high withstand voltage, and the voltage is generally greater than 1KV
The high-voltage ceramic capacitor has the voltage of 2KV, 3KV and 4KV, Often used in high-pressure situations, Up to 30KV
In the porcelain capacitor, the voltage below DC50V is generally called low voltage, DC100v ~ 500V is medium high voltage,
DC1000V ~ 6000V and is high voltage, and the voltage above DC6000V is ultra high voltage
Safety Y capacitor is also a high-voltage ceramic chip capacitor
The WEET WCA ceramic chip capacitor can be divided into class I porcelain, class II porcelain and class III porcelain. Class I porcelain, NPO, has good temperature, frequency and voltage characteristics. Because the dielectric constant is not high, the capacity is not large; class II porcelain, X7R comes next, has good temperature and voltage characteristics; class III porcelain has high dielectric constant, so the capacity can be large, but the temperature and voltage characteristics are not good, High voltage ceramic capacitor is generally small in size.
In addition, after breakdown, the ceramic capacitors tend to be in a short circuit state(this is its weakness) and after the film capacitor fails, it is generally in an open circuit state.The capacitance of high-voltage ceramic depends on the occasion of use, and the typical function can eliminate high-frequency interference.High voltage ceramic capacitors used in high power and high voltage fields are required to be small, high voltage withstand and good frequency characteristics.In recent years, with the progress of materials, electrodes and manufacturing technology, the development of high-voltage ceramic chip capacitor has made great progress and has been widely used. High voltage ceramic capacitor has become one of the indispensable components of high power and high voltage electronic products.
