APPLICATION INFORMATION

When the resistor dissipates power, a temperature rise above the ambient temperature occurs, dependent on the thermal

resistance of the assembled resistor together with the printed circuit board. The rated dissipation applies only if the permitted

film temperature is not exceeded.

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.
