Description
Switching Spark Gaps (SSG) are active components that work reliably even after igniting thousands of times. Switching Spark Gaps utilize the advantages of arc discharge principle: The enormous speed at which the arc is formed (<50 ns) as well as the high current capability allow the generation of short pulses of 10µs pulses with extremely high current or voltage rise times and low power loss. They can be used in all applications where high voltage pulses must be generated such as for the ignition of HID xenon lamps in automotive headlights.
Cautions and warnings
Switching spark gaps may be used only within their specified values.
Damaged switching spark gaps must not be re-used.
