Capacitors

Capacitors for Medium Ripple Filtering

Medium ripple filtering capacitors are optimized for filtering voltages derived from single phase bridges, in extended frequency ranges.

Their outstanding self-healing properties guarantee high reliability performance.

Applications :

- Filtering in medium power single phase rectification
- Filtering in multi-phase rectification
- Medium current pulses
- D.C. Voltage blockage
- All situations where a capacitor is permanently charged (or only partially discharged).
