Capacitors

Capacitors for Low Ripple Filtering

These capacitors are optimized for filtering of rectified voltages derived from mono-, tri- or multi-diode bridges. They are especially adapted to the industrial frequency range.

Their outstanding self-healing properties guarantee high reliability performance.

Applications :

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

- Rated voltage : from 2 to 60 kV
- Standard Capacitance tolerance : +/-10% (up to +/-5% on request)
- Maxixmum current : up to 2,2 Arms at 50 Hz
- Frequency range : up to 30 kHz
- Loss factor : < 80 x 10^-4 at 1kHz
- Operating temperature : 0°C to 45°C
- Storage temperature : -10°C to 50°C
- Standard life time : 25 000 hours (up to 100 000 hours on request)
 
Standard design :

- Case shape : cylindrical or plane-parallel
- Case material : Phelonic resin, laminate paper bakelite, PVC, metal
