Electrical Data
Capacitance
range: 140 µF to 8250 µF Rated voltages:
450VDC, 900VDC, 1500VDC Capacitance tolerance: ±10% Operating temperature range:
-55°C to +85°C (+105°C on request) Insulation resistance at +20°C: > 30000 sec (MxµF)
(mean value: 100000 sec)
Measuring voltage: 100V/1 min.
Self-inductance:< 50 nH depending on tab configuration ESR at +20°C:
Excessive mechanical strain, e.g. pressure or shock onto the capacitor body, is to be avoided during mounting and usage of the capacitors. When fixing the capacitor the screw torque is to be limited to max. 5 Nm.
