TDK has opened a new plant in Pyeongtaek, Korea, some 70km south of Seoul, for the production of ferrite cores. The new factory, which started operations in October 2011, expands the company’s capacity in response to the growing demand for high-performance coils and transformers. These are used for EMI protection and impedance matching, especially in multifunctional mobile devices and vehicles.

The Pyeongtaek factory builds on TDK’s long heritage as the pioneer in the field of ferrites and its advanced know-how in the manufacture of miniaturized and highly efficient products. The plant will initially focus on the development and pilot production of coils and transformers and the production of small ferrite cores. The products manufactured in Pyeongtaek will be used primarily for smartphone and automotive applications in the growing Korean and Chinese markets. Moreover, it is designed to manufacture further products in the future. As an important part in the TDK group’s global manufacturing network, the Pyeongtaek plant will cooperate closely with the other plants for ferrite materials, cores and products in China, Japan, India, and the Czech Republic. Among others, the facility is certified to the demanding ISO/TS 16949 standard.
