ST-0350 Series Sparctube™ Switching Spark Gap
Description
®
™
Bourns Sparctube Series is a range of switching spark gaps designed specifically for voltage controlled switching of capacitive
discharge circuits where a high energy, low loss, fast rate of switching is required. This series is ideally suited for applications where a
capacitive discharge is utilized with a transformer to obtain pulses of very high voltage levels in the order of several thousand volts.
