Spark Gap

Spark GapsWe offer a range of two- and three-electrode gas-filled spark gaps (signified correspondingly as R and RU) with DC hold-off voltages from 0.8 kV to 100 kV.

The spark gaps applications include medical lithotripsy, crowbar circuits, high di/dt switches for laser firing and high energy switches.

The spark gaps with DC hold-off voltage in the range 0.8-50 kV are available. The tubes do not contain any toxic and radioactive substances. Mounting position – any. Cooling – natural.
