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

/h,
π
Q
= 0,3), corresponding to MIL Level P, is superior to level E5 (10

replacement

These figures provide a user advantage over the prescriptions or requirements of EN 140401-803.
