Ohmite WFH90L1K0JE Aluminum Housed Wirewound Resistor
Ohmite's WFH series aluminum housed wirewound resistors utilize a flat core winding technology, resulting in a low-profile design and superior thermal characteristics compared to conventional wirewound resistors. This design enables close mounting of heat-sensitive components due to the minimal temperature rise on the aluminum profile. The large mounting surface eliminates the need for heat sink compound, simplifying installation and improving performance. These resistors are suitable for a wide range of industrial applications requiring high power dissipation and precise resistance values.
