Switching spark gap - 2RK-8 Series
Witching spark gaps designed specifi cally for voltage controlled 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.
Features
Extremely long life time
1. Stable performance over life
2. Insensitive performance against variations in
temperature
3. Low switching losses
4. Very short breakdown time
5. High reliability by robust design
6. RoHS compatible
