porcelain capacitor

Detailed Product Description

porcelain capacitor:

The porcelain capacitor is a dielectric whose main material is titanium oxide, barium titanate or sronitium. It becomes ceramic capacitor after a process called silver coating and is widely applied in various kinds of electronic equipments.

Basically, ceramic capacitor can be classified into 3 classes, according to distinct application features.

Class I: temperature compensation type capacitor (T. C.)
Temperature compensation capacitors mainly consist of titanium. They have the characteristics of low constant, low losses (high quality factor), high stability and liner temperature relationship. All these features suited its capability for temperature compensating mainly use in resonant circuits or in other circuits for which high Q and high temperature base stability of circuit constant are required.

Class II: high dielectric constant
High dielectric mainly consists of barium titanate. It is known as Hi-k because of its high power factor. These capacitors which have the characteristics of high capacitance value, small internal impedance and excellent power factors are widely used in electronic circuits such as coupling, decoupling and by pass purposes.

Class III: semi conductive
These disc type semi conductive capacitors are reformed smaller size with larger capacitance than usual Hi-k type capacitors. These capacitors are widely used in electronics circuits such as constant determination, coupling and by pass purposes.
