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
• The failure rate level E6 (10-6/h, πQ = 0,3), corresponding to MIL Level P, is superior to level E5 (10-5/h, πQ = 1) and thus may be used as a
replacement
(1) These figures provide a user advantage over the prescriptions or requirements of EN 140401-803.
