Description
Bourns® Sparctube®ꢀSwitchingꢀSparkꢀGapꢀSeriesꢀisꢀaꢀrangeꢀofꢀswitchingꢀsparkꢀgapsꢀdesignedꢀspecificallyꢀforꢀvoltageꢀcontrolledꢀ
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.
