About TDK


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; production engineering technology; and product design 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.


Thanks to two historic changes —Digital transformation (DX), utilizing IoT, AI and other technologies; and Energy transformation (EX), including through the expanded use of renewable energy— the importance of electronic components and devices is reaching unprecedented heights.
TDK will accelerate its efforts in DX and EX, keeping our sights not only on our customers but on the end consumer as we strive to offer technology that can contribute to a better future.


TDK has over 250 sites in more than 30 countries and regions around the world, with about 130,000 employees. Of these, about 90% are employed at sites outside of Japan. TDK’s use of a highly diverse global workforce is a major strength, and a driver of our growth.


Today, achieving a sustainable society is an issue deeply integral to a company’s reason for being. To realize the TDK Group’s sustainability vision of “Technology for the well-being of all people,” TDK will continue to contribute to society by creating technology and offering products of value.
