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

Notes
(1)
For size 0402 until 1206 the measuring conditions are in acc. to EN 140401-802. For all other sizes the result depends on the solder pad
dimensions.
(2)
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.
