and at 500 VDC for UR ≥ 500 VDC
Between terminals:
C ≤ 0.33 µF: ≥ 100 000 MΩ

Inductance
Approximately 6 nH/cm for the total length of capacitor
winding and the leads.
Pulse rise time
The capacitors can withstand an unlimited number of pulses
with a dU/dt according to the article table. For peak to peak
voltages lower than the rated voltage (UPP < UR), the specified
dU/dt can be multiplied by UR/UPP.
