Ohmite WFH330L250JE Aluminum Housed Wirewound Resistor
Ohmite’s WFH series resistors utilize a flat core winding technology, resulting in a low-profile design and excellent thermal characteristics. These resistors are ideal for applications where space is limited and efficient heat dissipation is critical. The aluminum housing provides a large mounting surface, eliminating the need for heat sink compound. They are commonly used in power control, motor speed control, and other industrial applications requiring high power handling and precise resistance values.
