Capacitors

Discharge With High Repetition Rate

These capacitors are optimized for very high current discharges, with high polarity inversion ratio and very high repetition rates.

Their outstanding self-healing properties guarantee high reliability performance.

Applications :

- Very fast energy restitution
- Generation of normalized lightning waves (8/20µs, 1,2/50µs, etc...)
- Lithotripsy
- Pulse Forming Network - delay lines
- Possibility of polarity inversion between successive discharges
