Note
(1) 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. The applicable voltage is
limited by maximum power.
Brochure Type
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.
