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 values: Typically R05 5% R047 10%
Temperature coefficients: Typical values < 1K 100ppm Std. > 1K 25ppm Std. For lower TCRs please contact Arcol
Insulation resistance (Dry): 10,000 M minimum
Power dissipation: At high ambient temperature dissipation derates linearly to zero at 200C
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

that a heat sink compound be applied between the resistor
