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 Temp.
