EPCOS

EPCOS is a brand of electronic components that originated as part of Siemens AG’s Electronic Components division and later became a standalone company. The product portfolio traditionally includes passive components such as capacitors (ceramic and film types), inductors, varistors, ferrites, and EMI suppression devices, as well as related sensors used in a range of applications from consumer electronics to automotive and industrial equipment.

In 2009, the Japanese company TDK Corporation acquired EPCOS from Siemens for a sum reported around one billion euros. Following the acquisition, EPCOS was integrated into TDK’s electronics business, and its products were marketed within the TDK Electronics portfolio, with the EPCOS name continuing to accompany many product lines in various markets. In 2019, TDK reorganized its operations under the TDK Electronics business group, further consolidating EPCOS into the group while continuing to leverage the EPCOS brand for many components.

TDK Electronics, including the EPCOS brand, serves a global customer base and maintains manufacturing and development activities in Europe and Asia. EPCOS components are commonly used in power supplies, automotive electronics, lighting, consumer devices, and industrial equipment, where reliability and compact form factors are important. The brand remains recognized for a broad range of passive components and related technologies within the wider TDK portfolio.
