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
Characteristics
Tolerance (Code):
Standard ±5% (J) and ±10% (K). Also available ±1% (F), ±2% (G) and ±3% (H)
Tolerance for low Ω values:
Typically ≥ R05 ±5% ≤ R047 ±10%
Temperature coefficients:
Typical values < 1K 100ppm Std. > 1K 25ppm Std. For lower TCR’s please contact Arcol
Insulation resistance (Dry):
10,000 MΩ minimum
Power dissipation:
At high ambient temperature dissipation derates linearly to zero at 200°C
Ohmic values:
From R005 to 100K depending on wattage size
Low inductive (NHS):
Specify by adding N before HS Series code, e.g. NHS50
NHS ohmic value:
Divide standard HS maximum value by 4
NHS working volts:
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
HS300
base and heat sink chassis mounting surface. It is essential that
the maximum hot spot temperature of 200°C is not exceeded,
HS250
therefore, the resistor must be mounted on a heat sink of
correct thermal resistance for the power being dissipated.
