With ratings from 90-330 watts, the new range of WFH flat, heatsinkable, wirewound resistors from Ohmite offer cost savings, weight and space savings, plus superior thermal efficiencies over conventional aluminum housed resistors.

Featuring solder, cable, and “Fast-On” termination options, WFH resistors are wound on flat cores rather than cylindrical and then housed in flat aluminum extrusions which are only 12.6mm in height across the entire product range. Heat is efficiently spread through the wide aluminum baseplate to the heatsink.

The WFH series has the added advantage of being tappable, a feature not available in MIL-R-18546 type resistors and the costs for the WFH series are progressively more competitive as size increases due to the fact that a common aluminum extrusion is used throughout the range.
