Please refer to APPLICATION INFORMATION below.
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.
