product feature:
1.be used at filtering high frequent interference the signal of signal wire and electrical source wire.
2.fix conveniently.
3.have good effect at input and output coupling separate.
4.have some interior circuit structure,be fit for different source impedance and load impedance.
5.special electrode technology,have good endure welding,capacitance stabilization,the temperature applicability is wide,endure high voltage and so on.

Model C:single capacitor structure,be fit for signal wire filter and DC source wire filter.
Model L:different fix style(direction),can separatedly use the place which high source impedance,low load impedance,or low source impedance,high load impedance.
model Pi:Be fit for the place which high source impedance together with high load impedance,and reference control feature requirment is high(insertion loss).
Model T:be fit for the place which low source impedance together with low load impedance,and reference control feature requirment is high(insertion loss).
