Temp. Rise & Power Dissipation
Manufactured in line with the requirements of MIL
18546 and IEC 115, designed for direct heatsink
mounting with thermal compound to achieve maximum
performance.
Heat Dissipation
Surface temperature of resistor related to power dissipation.
The resistor is standard heatsink mounted using a proprietary
heatsink compound.
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.
Ordering Procedure
