RARA FRH 50C Series

The FRH 50C metal clad thick film resistor series from RARA offers a power rating of up to 25W on a heat sink and 8W in free air with available resistance values between 1kΩ and 2MΩ (non-inductive design). These high power resistors are available with tolerances of ±1%, ±2%, ±5% and ±10.0%. The FRH 50C series from RARA has a cement moulding within an aluminium housing which mounts on to a chassis to utilise the heat sink effect, all with a temperature range from -15°C up to +105°C
