The diverse range of EPCOS portfolio includes capacitors, ferrites and inductors, piezo and protection devices, as well as sensors.

Electronic components and systems are found today in almost every item of electrical equipment, where they are essential for guaranteeing perfect functionality. They perform key functions in cars and trucks, industrial machine tools and in electric railways, wind farms and photovoltaic plants, as well as in washing machines, LED lamps, smartphones, notebooks and televisions. In all these applications EPCOS solutions ensure the supply of power, 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.

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 vehicles, industrial equipment and household appliances, but also in power engineering, and smartphones, tablets and wearables.

Sensors and sensor systems include temperature sensors, which, for example, are used in vehicles in systems for reducing emissions. Such components are also used in household appliances 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. Rounding out the portfolio of sensors is the Tronics product spectrum, which consists primarily of inertial sensors that, among other things, are able to sense acceleration and rotation.
