A kind of NPO dielectric with temperature compensation, this kind of capacitor has the most stable electrical performance, basically does not change with temperature, voltage and time, and belongs to the type of ultra-stable, low-loss capacitive material. It is suitable for high frequency, ultra high frequency and very high frequency circuits requiring high stability and reliability.
The second class is X7R dielectric with high dielectric constant. Because X7R is a kind of strong dielectric, it can produce capacitors with larger capacity than NPO dielectric. The performance of this kind of capacitor is relatively stable. With the change of temperature and voltage time, the characteristic performance of the capacitor is not obvious, so it belongs to the type of stable capacitor material. It is used in straight, coupling, near circuit, filter circuit and high reliability middle and high frequency circuit.
