Typically ≥ R05 ±5% ≤ R047 ±10%
Typical values < 1K 100ppm Std. > 1K 25ppm Std. For lower TCR’s please contact Arcol
10,000 MΩ minimum
At high ambient temperature dissipation derates linearly to zero at 200°C
From R005 to 100K depending on wattage size
Specify by adding N before HS Series code, e.g. NHS50
Divide standard HS maximum value by 4
Divide standard HS maximum working voltage by 1.414
Temp. Rise & Power Dissipation
Surface temperature of resistor related to power dissipation.
The resistor is standard heatsink mounted using a proprietary
heatsink compound.

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.
