Please refer to APPLICATION INFORMATION below.  
APPLICATION INFORMATION  
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 is  
not exceeded. Furthermore, a high level of ambient temperature or of power dissipation may raise the temperature of the solder  
joint, hence special solder alloys or board materials may be required to maintain the reliability of the assembly.  
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. At the maximum permissible film temperature of 155 °C the useful lifetime is specified for 8000 h. The  
designer may estimate the performance of the particular resistor application or set certain load and temperature limits in order  
to maintain a desired stability.
