Fig.9 Multiplier of useful life as a function of ambient temperature and ripple current load.

IA = actual ripple current at

100 or 120 Hz.

IR = rated ripple current at

100 or 120 Hz, 105

°C.

For case codes 0405 to 1010 max.

IA/IR = 2.4.

(1) Useful life at 105

°C and IR applied:

case codes 0405 to 0605:

2000 hours

case codes 0807 to 1014:
