APPLICATION INFORMATION

The power dissipation on the resistor generates a temperature rise against the local ambient, depending on the heat flow

support of the printed-circuit board (thermal resistance). 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.

Note
