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)

Typically ≥ R05 5% ≤ R047 10%

Tolerance for low Ω values:

Temperature coefﬁcients:

Insulation resistance (Dry):

Power dissipation:

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

Ohmic values:

Low inductive (NHS):

NHS ohmic value:

Specify by adding N before HS Series code, e.g. NHS50

Divide standard HS maximum value by 4

NHS working volts:

Divide standard HS maximum working voltage by 1.414

Temp. Rise & Power Dissipation

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.
