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 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.
Ordering Procedure:
- Standard Resistor: To specify standard: Series, Watts, Ohmic Value, Tolerance Code, e.g.: HS25 2R2 J
- Non Inductive Resistor: To specify add N, e.g.: NHS100 10R J
Heat Dissipation:
- Whilst the use of proprietary heat sinks with lower thermal resistances is acceptable, uprating is not recommended.
- For maximum heat transfer, it is recommended that a heat sink compound be applied between the resistor base and heat sink chassis mounting surface.
- It is essential that the maximum hot spot temperature of 200C is not exceeded, therefore, the resistor must be mounted on a heat sink of correct thermal resistance for the power being dissipated.
Temp. Rise & Power Dissipation: Surface temperature of resistor related to power dissipation. The resistor is standard heatsink mounted using a proprietary heatsink compound.
