Ohmite | Arcol HS Series – Aluminum Housed Resistors:

Globally the No 1 range of aluminum housed power resistors ranging from 10 watts to 300 watts. They are manufactured to meet the requirements of MIL 15546 and IEC 115 and are of course RoHS compliant. Designed for direct heatsink mounting with thermal compound to achieve maximum performance.

Series Features:

High Power to volume

Wound to maximize High Pulse Capability

Values from R005 to 100K

Custom designs welcome

RoHS Compliant

Family Characteristics of Features:

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
