Ohmite WFH90L25RJE Aluminum Housed Wirewound Resistor
Ohmite's WFH series resistors are aluminum housed wirewound resistors utilizing a flat core winding technology. This design enables a low profile and superior thermal transfer characteristics, making them suitable for applications where heat dissipation is critical. The large mounting surface eliminates the need for heat sink compound, and the close mounting of heat-sensitive components is possible due to the minimal temperature rise on the aluminum profile. These resistors are ideal for various industrial applications requiring high power handling and reliable performance.
