Ceramic Filter Cases

Ceramic filter is made of lead zirconate titanate ceramic material, this ceramic material is made into sheets, coated with silver as electrodes, after dc high voltage polarization, piezoelectric effect.
It plays the role of filtering and has the characteristics of stability and good anti-interference performance. It is widely used as frequency selective components in TV, video recorder, radio and other electronic products.
It has the advantages of stable performance, no adjustment and low price, and replaces the traditional LC filter network.
