Capacitors

Low Repetition Rate Bipolar Discharge Capacitors

These capacitors are optimized for normalized lightning waves generation, presenting very high peak currents and energy integrals. The voltage polarity can moreoover be inverted after each successive charge/discharge cycle.

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
- Possibility of polarity inversion between successive discharges

Performance :

- Rated Voltage : from 2 to 60 kV
- Standard Capacitance Tolerance : +/-10% (up to +/-5% on request)
- Peak Current : up to 20kA
- Reverse Voltage : up to 60%
- Frequency Range : up to 2Hz
- Loss Factor : < 25 x 10-4 at 1kHz
- Serial Inductance : starting from 100nH
- Operating Temperature : 0°C to 45°C
- Storage Temperature : -10°C to 50°C
- Standard Life : 100 000 discharges (up to 10 000 000 discharges on request)
 
Standard design :

- Case shape : cylindrical or plane-parallel
- Case material : Phelonic resin, laminate paper bakelite, PVC, metal
- Terminals : axial leads in brass, thread rods or screw holes with contact plates
 
Technology :

- Self healing : yes
- Dielectric : combination paper and polypropylen
- Polarized : no
- Impregnation : oil (no P.C.B.)
- Potting : polyurethane resin
 
Custom :

- Compliance with UL94V0 or other standards on request
- Matching with customers requirements on :
• Rated voltage, up to 300kV,
• Specific tolerance on capacitor value,
• Operating temperature, up to 70°C,
• Inset of specific fastening nuts or bolts,
• etc...
