Notes
•
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.
•
Marking: No marking on device, on the label only
•
Packaging: See appropriate catalog or web pages
•
Power rating depends on the max. temperature at the solder point, the component placement density and the substrate material

Rated voltage:
PxR
(3)
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 of 155 °C is not exceeded.
