APPLICATION INFORMATION The power dissipation on the resistor generates a These resistors do not feature a limited lifetime when temperature rise against the local ambient, depending on operated within the permissible limits. However, resistance the heat flow support of the printed circuit board (thermal value drift increasing over operating time may result in resistance). The rated dissipation applies only if the exceeding a limit acceptable to the specific application, permitted film temperature is not exceeded. Furthermore, a thereby establishing a functional lifetime. At the maximum high level of ambient temperature or of power dissipation permissible film temperature of 155 C the useful lifetime is may raise the temperature of the solder joint, hence special specified for 8000 h. The designer may estimate the solder alloys or board materials may be required to maintain performance of the particular resistor application or set the reliability of the assembly. The applicable voltage is certain load and temperature limits in order to maintain a limited by maximum power. desired stability.
