Passive Components

Passive Components

TDK’s passive components have their roots in the magnetic material ferrite, originally invented in 1930 and certified as an IEEE Milestone in 2009. Ever since its beginnings, the company has consistently blazed a path of innovation, making products smaller, lighter and thinner and integrating them into modules, thereby contributing to the progress of electronic devices such as smartphones, PCs, and automobiles. Today TDK offers a wide range of passive components including ceramic, aluminium electrolytic and film capacitors, as well as inductive devices, high-frequency components, and piezoelectric material products and circuit protection components. These components are marketed under the product brands TDK and EPCOS.
