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 For technical questions, contact: filmresistors.thickfilmchip@vishay.com Document Number: Revision: 3-Oct-08

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 55 C is not exceeded.
