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: < 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) ohmic value: Divide standard HS maximum value by 4.
- NHS working volts: Divide standard HS maximum working voltage by 1.414.
Heat Dissipation
For maximum heat transfer, it is recommended that a heat sink compound be applied between the resistor base and heat sink chassis mounting surface. The maximum hot spot temperature of 200C must not be exceeded, therefore, the resistor must be mounted on a heat sink of correct thermal resistance for the power being dissipated.
Ordering Procedure
- Standard Resistor: Specify by Series, Watts, Ohmic Value, Tolerance Code (e.g., HS25 2R2 J).
- Non Inductive Resistor: Specify by adding N before HS Series code (e.g., NHS100 10R J).
