TDK was founded in 1935 to commercialize ferrite, a magnetic material. The innovation of TDK’s founder created great value to the world that had not existed before. He believed strongly in the potential of ferrite and built a venture business with origins at the Tokyo Institute of Technology even though the new material’s wide-ranging uses were yet to be discovered.

TDK has continued to create products with originality and a high level of value through manufacturing excellence —Monozukuri— making use of the five core technologies of materials technology starting with ferrite; process technology to maximize all of a material’s properties; evaluation and simulation technology; product design technology; and production technology. Today, TDK offers its excellence in manufacturing across a range of product groups, including capacitors, inductors, transformers, sensors, actuators, magnetic heads, magnets, power supplies, batteries, and many types of electronic components and electronic devices.

TDK has more than 200 sites in over 30 countries and regions around the world, with more than 100,000 employees. About 90% of those employees work at sites outside of Japan, and the rich diversity of our personnel is one of TDK’s greatest strengths. We will leverage that strength in our use of global human resources and global governance systems to ensure the success of our growth strategy.
