Ohmite PFE5K8R50E Edgewound Edgewound Resistor
OHMITE's PFE5K8R50E Powr-Rib Edgewound Resistor is engineered for demanding environments requiring high power dissipation and reliable performance. Constructed with a heavy resistance alloy on ceramic insulators and a metal mounting bracket, this resistor provides excellent thermal stability and resistance to oxidation and corrosion. The edgewound design ensures low resistance and high power capacity, making it ideal for applications such as power supplies, motor drives, and braking resistors. The clamp-type terminals allow for easy adjustment of resistance values, enhancing versatility and adaptability. Its robust construction and reliable performance make it a preferred choice for industrial and commercial applications.
