Notes

• These resistors do not feature a limited lifetime when operated within the permissible limits. However, resistance value drift increasing over

operating time may result in exceeding a limit acceptable to the specific application, thereby establishing a functional lifetime.

• Failure rate level E8 (10^-8/h, _Q= 0.03), corresponding to MIL level S, is superior to level E7 (10^-7/h, _Q= 0.1), E6 (10^-6/h, _Q= 0.3) or E5

(10^-5/h, _Q= 1) and thus can be used as a replacement.
