Temperature Coefficient is dependent on the resistant range. These are as follows; ±100PPM/°C (0.1Ω – 0.976Ω), ±50PPM/°C (1Ω – 19.6Ω) and ±20PPM/°C (20Ω+).
RH Series Description
The RH series from RARA are metal clad wirewound resistors with an aluminium housing covering cement moulding. These resistors offers a power rating from 20W up to 50W* on a suitable heat sink and 8W or 10W in free air depending on the model. The resistance range varies depending on the model and inductivity. These range from 0.1kΩ to 50KΩ. Full details can be found on the individual product pages. These high power resistors are available with tolerances of ±0.1% (>1Ω), ±0.25% (>0.4Ω), ±0.5% (>0.2Ω), ±1% (>0.1Ω), ±2% (>0.05Ω) and ±5% (>0.02Ω). All RH resistors have an operating temperature of -55°C to +250°C. Derating is required for reduced chassis mounting area and for high ambient temperatures.
