Spark Gap Switches (Untriggered)

Datasheet

Spark Gap Switches R-90 and the devices of RK-series are the sealed-off ceramic-metal gas discharge tubes designed as untriggered switches for use in pulsed circuits of devices with enhanced demands to switching speed, break-down voltage stability and a level of power maintenance.
The devices feature an extremely small size, they are capable of operation under complicated climatic and mechanic conditions (for example, at temperatures up to +250 0C), and have an established reputation of reliability for use in ignition systems for aircraft jet engines, pulsed and other kinds of pulse apparatus.
