TY-OHM was established in 1958, the pioneer of resistors manufacturer in Taiwan. We first made carbon film and low-end wire wound resistors. In 1970 we made a venture cooperation with Japan Resistor Mfg. Co., Ltd. (JRM), producing metal oxide film and high-end wire wound resistors. In 1975 we made another technical cooperation with an American company named Kidco for getting how to make 1% tolerance of precision metal film resistors. In 1985, we developed resistor network and fusible resistors; SMD components of chip resistors and chip resistor networks were marketed in 1992. The latest power SMD resistors were introduced to customers in 2001.

From the beginning, we have been paying special attention to quality system. As with JRM cooperation, we learned the skill to produce and inspect quality products. We obtained “Class A” good quality approval from local government in 1980, and ISO-9002 certificate in 1995 and Philips Lighting Oss award for excellent performance in quality, delivery and support in 1996.  Our headquarters is in Taiwan, where we have a factory for small-scale pilot run production. The main production sites are in China, one in Shenzhen and the other one in Suzhou. Total employees of TY-OHM group is 650, providing a variety of resistors to mobile phones, tablets, notebooks, lighting, power supplies, solar panels, etc.
