POWER DISSIPATION (WATTS)
Heat Dissipation
Heat dissipation: Whilst the use of proprietary heat sinks
with lower thermal resistances is acceptable, uprating is not
recommended. For maximum heat transfer it is recommended
that a heat sink compound be applied between the resistor
base and heat sink chassis mounting surface. It is essential that
the maximum hot spot temperature of 200°C is not exceeded,
therefore, the resistor must be mounted on a heat sink of
correct thermal resistance for the power being dissipated.
