Note: 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.
1)
The power dissipation on the resistor generates a temperature rise against the local ambient, depending on the heatflow support of the
printed-circuit board (thermal resistance). The rated dissipation applies only if the permitted film temperature is not exceeded.
