Power Resistors

	POWER WIREWOUND RESISTORS

Direct's new flat core winding technology allows for wirewound heatsinkable resistors affording a very low profile, and superior thermal transfer characteristics when compared to conventional aluminum housed type.

Applications for electrical industry range from large capacity metal clad, nonflammable fixed wirewound, nonflammable wave shape ribbon, slide type wirewound, box type, wirewound starter, to nonflammable flat wirewound type.

Direct extends a complete line for both military and commercial applications.
