Ohmite PFR5K11R0E Edgewound Round Wire Resistor
The OHMITE PFR5K11R0E is a heavy-duty edgewound resistor designed for applications requiring high power capacity and robust performance. Constructed with a resistance alloy mounted on ceramic insulators and supported by a metal mounting bracket, this resistor is built to withstand harsh operating conditions. The edgewound design provides low resistance and high power handling capabilities, while the round wire construction offers a balance of performance and cost-effectiveness. Typical applications include power transmission, motor control, and industrial heating.
