APPLICATION INFORMATION
When the resistor dissipates power, a temperature rise above the ambient temperature occurs, dependent on the thermal 
resistance of the assembled resistor together with the printed circuit board. 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

Note
 The presented operation modes do not refer to different types of resistors, but actually show examples of different loads, that lead to 
different film temperatures and different achievable load-life stability (drift) of the resistance value. 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
