CERAMIC CAPACITOR 1.Ceramic Capacitors The ceramic is a dielectric whose main material is Titanium Oxide Barium Titanate or Strontium.it becomes ceramic capacitor after aprocess called silver coating and is widely applied in various kind of electronic equipment ’锶料 ’ 2. Classification 類 Basically’ceramic capacitor can be classified 3 classes’according to distinct application features. Class 1: Temperature Compensation Type Capacitor(T.C.) 類 1:度 Temperature compensation capacitor mainly consist of Titanium. They have the characteristics of low constant’ low losses(high quality factor)’high stability and linear 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. 度’數’’ ’量度’ 路路 1 Class 2: High-Dielectric Constant Type Capacitor(HI-K) 類 2:數 High-dielectric are mainly consist of Barium Titanate.It is known as Hi-k because of its high power factor. These capacitors which have the characteristics of highcapacitance value’small internal impedance and excellent power factors are widely used in electronic circuits such as coupling’decoupling and by pass purposes. ’ 率數”Hi-K”’類量..’路 流.路 Class 3: Semi-Conductive Type Capacitor(S.C.) 類 3: These disc type semiconductve capacitors are reformed smaller size widh larger capacitance than usual Hi-K type ceramic capacitors.These capacitors are widely used in electronics circuits such as constant determination’coupling and by-pass purposes. 數’更’量更’ 路.路
