Rolling Meadows, Illinois - December, 2004 - Ohmite Manufacturing Company announces the introduction of their new WFH Flat Heatsinkable Wirewound Resistors. With ratings from 90-330 watts, this family offers cost savings, weight and space savings, plus superior thermal efficiencies over conventional aluminum housed resistors. This resistor family features solder, cable, and "Fast-On" termination options.

WFH resistors are wound on flat cores rather than cylindrical. They are housed in flat aluminum extrusions, 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. Costs for WFH series are progressively more competitive as size increases, due to the fact that a common aluminum extrusion is used throughout.

Pricing ranges from $17 - $42 each for 330W units in quantities of 1 to 500.
