Ceramic multilayer chip capacitors, also known as high voltage patch capacitors, are widely used in automotive and power supply fields.But do you know, there are three kinds of high voltage patch capacitor medium, different medium high voltage patch capacitor role is not the same, below we will understand the role of high voltage patch capacitor.

High voltage patch capacitance

There are three kinds of high voltage patch capacitors: NPO, X7R and X5R

The high voltage patch capacitance of NPO medium ACTS as a filter in high stable oscillation circuit.Because its performance is relatively stable and high heat resistance.

The high voltage patch capacitance of X7R medium plays the role of filtering, bypass, separation and coupling in the circuit.Since its medium is a strong dielectric, its capacity is larger than that of NPO, and its performance does not change significantly with the change of external temperature and voltage time.

The high voltage patch capacitance of X5R medium is the function of coupling, bypass, targeting and filtering in the whole electronic machine.Because of its high permittivity, it is often used to produce large-capacity capacitors with larger specific capacity and higher nominal capacity.
