Ohmite PFE5KR500E Edgewound Power Resistor
OHMITE's PFE5KR500E Edgewound Power Resistor is a robust solution for applications requiring high power dissipation and low resistance. Constructed with a heavy resistance alloy mounted on ceramic insulators and a metal mounting bracket, these resistors are built to withstand demanding environments. The edgewound design provides excellent heat dissipation and the clamp-type terminals allow for adjustable resistance values. Ideal for industrial heating, braking, and power supply applications.
