The switch tube 2RK-5 series ceramic gas discharge tube is an active component. It can still work reliably after 100,000 ignitions. It makes full use of the advantages of the arc discharge principle, that is, high speed (forming an arc less than 50 ns) and Good current Ability to generate short pulses of 10 µs, its voltage or current multiplier is extremely high, and low power consumption. Switching discharge tubes can be used in all applications that require the generation of high-voltage pulses, such as the ignition of HID (high-pressure gas discharge lamps) xenon lamps in automotive headlights. Volume: 5.5×6.0mm, voltage range: 230～800V.
