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 and 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
