The FRH series from RARA are metal clad thick film resistors with an aluminium housing covering cement moulding. These resistors offers a power rating of 15W or 25W on a suitable heat sink and 5W or 8W in free air depending on the model. The available resistance values range between 1kΩ and 2MΩ (non-inductive design). These high power resistors are available with tolerances of ±1%, ±2%, ±5% and ±10% and a minimum ohmic value of 1kΩ. FRH resistors have an operating temperature of -55°C to +250°C. Derating is required for reduced chassis mounting area and for high ambient temperatures.
