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. 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.
Notes
• Radial version (RB, UB) cannot be qualified according to CECC so these can only be ordered with variant N or S.
