RMS (1) Permissible film temperature, 155 C F max. (1) Operating temperature range -55 C to 155 C -55 C to 155 C Permissible voltage against ambient (insulation): 1 min, U 300 V 500 V ins Note (1) 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.

A suitable low thermal resistance of the circuit board assembly must be safeguarded in order to maintain the film temperature of the resistors within the specified limits.
