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. However, resistance value drift increasing over operating time may result in exceeding a limit acceptable to the specific application, thereby establishing a functional lifetime.

A suitable low thermal resistance of the circuit board assembly must be safeguarded in order to maintain the film temperature of the resistors within the specified limits. Please consider the application note Thermal Management in Surface-Mounted Resistor Applications (www.vishay.com/doc 28844) for information on the general nature of thermal resistance. The resistance value is influenced by the resistance of the terminations. The exact resistance value of the soldered part on the PCB may deviate depending on e.g. solder quantity, pad layout, and soldering method. The resistance value of the unmounted part can be verified by a 4-point probe on the top side termination as shown below. 600 m 870 m Fig. 1 Revision: 24-Mar-16 Document Number: 28847 2 For technical questions, contact: thinfilmchip vishay.com THIS DOCUMENT IS SUBJECT TO CHANGE WITHOUT NOTICE.
