APPLICATIONS
DESCRIPTION
All general purpose power applications
A homogeneous film of metal alloy is deposited on a high
grade ceramic body. After a helical groove has been cut in
Automotive electronics
the resistive layer, tinned connecting wires of electrolytic
Lighting ballast
copper or copper-clad iron are welded to the end-caps. The
resistors are coated with a red, non-flammable lacquer
which provides electrical, mechanical and climatic
protection. This coating is not resistant to aggressive fluxes
and cleaning solvents. The encapsulation is resistant to all
cleaning solvents in accordance with IEC 60068-2-45.

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.
