KOA Group manufactures and distributes quality resistors and other essential electronic components to support local and international customers from diverse market segments. Founded on March 10, 1940 and based in Japan, KOA has an extensive international network with presence in Asia, Europe, and USA.

With a history of more than twenty years in the manufacture and distribution of quality resistors together with advance manufacturing equipment and proprietary production process, KOA is poised for global growth and gears to be a world player in resistor technology. We produce resistors that are essential components used as current regulators for electrical and electronic circuitry. We develop and continuously improve our process technologies to manufacture our resistors efficiently meeting stringent quality standards and within a competitive cost structure framework. Our reliability test program ensures our resistors meet the highest international standards (MIL, JIS, EIA).

The Group's competitive edge is derived from its ability to provide customers with quality products in 'quick-turn' services through automated manufacturing facilities and a computerized distribution system. We achieve our goals of continuous improvement in efficiency and quality through our consistent on-going investment in the latest technology, manufacturing equipment, and human resource development.
