FRH series

Supporting Manufacturer Information


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 8Wย  in free air depending on the model. The available resistance values range between 1kฮฉ and 2Mฮฉ (non-inductive design). These high power resistors are available with tolerances of ยฑ1%, ยฑ2%, ยฑ5% and ยฑ10% and a minimum ohmic value of 1kฮฉ. FRH resistors have an operating temperature of -55ยฐC to +250ยฐC. Derating is required for reducedย  chassis mounting area and for high ambient temperatures.
