RESISTORS RESISTOR

	COMMERCIAL RESISTOR

DIRECT Electronics manufacturers a broad line of resistor passive components that will ensure the optimum performance of your circuit design. Advance manufacturing facilities are poised to ramp up with new designs, allowing us to take them to market with the shortest of lead times with more cheaper price.

General Purpose resistors Include from single chip SMD, to more complex arrays and networks. Fixed linear technologies include fusible, anti-surge power, wirewound, metal film, metal oxide, carbon film, non-inductive wirewound, cement type, and thick film resistors.

DIRECT also extends a complete line for both military and commercial applications and meets RoHS Directives.
