Note: For non-inductive resistors, specify by adding 'N' before the HS Series code (e.g., NHS50). NHS ohmic value is divided by 4 and NHS working volts are divided by 1.414 compared to standard HS values.
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 25ppm Std. For lower TCR's please contact ARCOL.
- Insulation resistance (Dry): 10,000 M minimum.
- Power dissipation: Derates linearly to zero at 200C at high ambient temperatures.
- Ohmic values: From R005 to 100K depending on wattage size.
Heat Dissipation: For maximum heat transfer, apply heat sink compound between the resistor base and heat sink chassis mounting surface. The maximum hot spot temperature of 200C must not be exceeded. Uprating is not recommended even with proprietary heat sinks with lower thermal resistances.
