Ohmite WFH90L750JE Aluminum Housed Wirewound Resistor
Ohmite's WFH series aluminum housed wirewound resistors utilize a flat core winding technology, providing a low profile and superior thermal transfer characteristics compared to conventional designs. This allows for close mounting of heat-sensitive components, minimizing temperature rise and eliminating the need for heat sink compound. The series is suitable for various industrial applications requiring high power dissipation and precise resistance values. The robust construction and high-temperature capabilities ensure reliable performance in demanding environments.
