TDK Electronics AG- Pulse Transformers

TDK Electronics AG, formerly known as EPCOS AG, is a leading global manufacturer of electronic components, modules and systems. Headquartered in Munich, Germany, the company was originally founded as a joint venture between Siemens and Matsushita in 1989, later becoming EPCOS AG, and was acquired by TDK Corporation of Japan in 2008. Today, the EPCOS brand is a product brand of TDK Electronics AG, focusing on passive electronic components such as capacitors, inductors, and surface acoustic wave (SAW) filters. The company offers an extensive portfolio of over 40,000 products, including aluminum electrolytic capacitors, film capacitors, multilayer ceramic capacitors (MLCCs), ferrites and inductors, and SAW components for frequency control and filtering. These components serve key markets including automotive electronics, industrial electronics, information and communication technology, and consumer electronics. TDK Electronics AG is renowned for its advanced ceramic technologies, delivering high-performance solutions in miniaturization, reliability, and environmental resistance. The company maintains a global manufacturing and sales network, with facilities in Europe, Asia, and the Americas. As part of the TDK Group, one of the world’s largest electronic component manufacturers, the EPCOS brand benefits from extensive R&D resources and a broad application reach. Its components are widely used in powertrain systems, advanced driver-assistance systems (ADAS), renewable energy inverters, and 5G base stations, making it a preferred supplier for tier-1 automotive and industrial OEMs. With a strong legacy in innovation and quality, TDK Electronics AG continues to shape the future of passive components through developments in material science and manufacturing precision.
