Parameters
Application conditions
Min Typical Max
Valid for whole temperature range and with
20μF foil capacitor and R3 placed in series
to the DUT. Change the value of R3 to get
the peak value of the first pulse to 33A.
Adjust 10s between each pulse. Vout=
400VDC. IInrush current= 33A. See Note 2
10000
Repetitive inrush current capability (cycles)
only for rectifiers
Take new samples.
Valid for whole temperature range and with
20μF foil capacitor and R3 placed in series
to the DUT. Change the value of R3 to get
the peak
value of the first pulse to 42A. Adjust 10s
between each pulse. Vout=500VDC. IInrush
current= 42A. See Note2
