High Power Metal Clad Resistors

The FRH 25C from RARA is a metal clad thick film resistor with an aluminium housing covering cement moulding. This resistor offers a power rating of up to 15W on a suitable heat sink and 5W in free air. The available resistance values range between 1kΩ and 2MΩ (non-inductive design). This high power resistor is available with tolerances of ±1%, ±2%, ±5% and ±10%.  FRH25C resistors have an operating temperature of -55°C to +250°C. Derating is required for reduced  chassis mounting area and for high ambient temperatures.
