Ohmite's WFH series wirewound resistors are designed with a flat core winding technology, providing a low profile and excellent thermal transfer characteristics compared to conventional aluminum housed resistors. This design allows for close mounting of heat-sensitive components, minimizing temperature rise on the aluminum profile and eliminating the need for heat sink compound. The resistors are available in a range of power ratings from 12 to 300 watts and resistance values from 0.22 ohms to 18,000 ohms, making them suitable for various industrial applications. They offer features like solder, cable, and 'Fast-On' termination options, along with a robust dielectric strength and insulation.
