Ohmite WFH90L100JE 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, reducing the need for heat sink compound. The series is suitable for applications requiring high power dissipation and robust performance, such as power supplies, motor drives, and braking resistors. The resistors are available with various resistance ranges and termination options to meet diverse application needs.
