EPCOS, a TDK Group Company, develops, manufactures and markets electronic components, modules and systems, focusing on fast-growing leading-edge technology markets, which include information and communications technology, automotive electronics, industrial electronics and consumer electronics. Thanks to the approximately 25,000 employees at more than 20 design and production locations and an extensive sales network outside of Europe, the company is well-equipped to work closely with customers and create the right solutions for them. Since February 2015, the two existing European sales channels for EPCOS and TDK products have been merged under the one roof of TDK Europe.
In fiscal 2015 (ending in March) EPCOS posted sales of about EUR 2.2 billion.

The diverse range of EPCOS components, modules and systems includes capacitors, ferrites and inductors, high-frequency components and modules, piezo and protection devices, as well as sensors.
Electronic components, modules and systems are found today in almost every item of electrical equipment, where they are essential for guaranteeing perfect functionality. In smartphones, notebooks and televisions they perform key functions, as they also do in cars and trucks, washing machines and LED lamps, in industrial machine tools or in electric railways, wind farms and photovoltaic plants. In all these applications EPCOS products process electrical signals, protect electronic circuits and ensure their fault-free operation.
Capacitors are used in all fields of electrotechnology and electronics. They store electric charges and they filter currents and voltages. The portfolio includes aluminum electrolytic and film capacitors, whose main applications are in power supplies and converters. Power capacitors ensure a stable supply of power in electric trains, for example. In addition, power capacitors are the key components for the transmission of high-voltage direct current, which enables energy to be transmitted over long distances with minimal loss.
Inductors fulfill two basic functions of electrotechnology, often simultaneously: the filtering of currents and the storage of electromagnetic energy. Ferrites, in turn, constitute the core of inductances and they bundle electromagnetic fields for the transmission of electrical signals and power. Inductors are used, among other things, in switch-mode power supplies for information and communications applications, as well as in automotive, industrial and entertainment electronics. EPCOS also manufactures components that ensure electromagnetic compatibility and, consequently, the fault-free operation of all types of electronic equipment.
The spectrum of high-frequency components and modules includes, in particular, surface acoustic wave (SAW) filter products and thus key components for information and communications technology. They filter frequencies and determine the performance as well as the reliable function of smartphones, tablets and wearables, for example. Furthermore, they are used in automobiles, e.g. in remote keyless entry systems, tire pressure monitoring systems and navigation devices.
Piezo and protection devices protect electronic circuits against voltage spikes and current surges. The portfolio includes surge arresters and switching spark gaps, thermistors, varistors and a comprehensive array of multilayer components that include piezo-actuators, as well as CeraDiodes and CeraLink capacitors. These components are essential, above all, in automotive, industrial and consumer electronics, but also in power engineering, communications and entertainment electronics.
Sensors and sensor systems include temperature sensors for motor vehicles, where they are used, for example, in systems for reducing emissions. Such sensors are also used in air-conditioning systems, refrigerators and industrial plants. To these must be added the pressure sensors and transmitters that are required primarily for the monitoring and diagnosis of pneumatic and hydraulic systems and for the control of valve and filter systems. One further field of application is medical technology, such as the machines for measuring blood pressure or for artificial respiration.
