HS
Aluminium Housed Resistors
Manufactured in line with the requirements of MIL 18546 and
IEC 115, designed for direct heatsink mounting with thermal
compound to achieve maximum performance.
High Power to volume
Wound to maximise High Pulse Capability
Values from R005 to 100K
Custom designs welcome
RoHS Compliant

Standard ±5% (J) and ±10% (K). Also available ±1% (F), ±2% (G) and ±3% (H)
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.
