Spark-Gap Capacitor

This SPARK GAP capacitor is designed for using in protector of CRT circuit and protector of circuit to the high potential pulse.
As this SPARK GAP capacitor (A Type) is a open type, so in the discharge, a spark does appear in the outside; (B Type) is a complete sealing type, so in the discharge, a spark does not appear in the outside, a discharge sound does not out, and this SPARK GAP capacitor withstand continuous discharge test for a time of not less than 10, 000 times.
As this capacitance value is very small, so for use in circuit, and impedance of circuit shall not change.
