Electronic components are found in nearly all electrical and electronic devices. A single car can contain as many as 10,000 such components. In mobile phones and lighting ballasts, notebooks and wind turbines, electronic components are instrumental in processing electrical signals, protecting electronic circuits and ensuring a regular, reliable power supply.
Capacitors are used throughout electrical engineering and electronics. They store electric charges and filter or regulate current and voltage in electronic circuitry. Our product portfolio includes aluminum electrolytic capacitors, film capacitors and power capacitors, and solutions for power factor correction.
Inductors fulfill two basic electrical functions at the same time: they filter current and store electromagnetic energy. Among other things, inductors are used in switch-mode power supplies for applications in information and communications technology, automotive, industrial and consumer electronics. Our portfolio also includes ferrites, which are the heart of inductors and concentrate electromagnetic fields to transmit electrical signals and power. Moreover, EPCOS also manufactures components that ensure electromagnetic compatibility (EMC) for the interference free operation of electrical equipment and devices of all kind.
Ceramic components are indispensable in automotive electronics and household appliances, in particular, but also in telecommunications and entertainment electronics. They filter electrical signals, measure physical parameters such as temperature and protect electronic circuitry against overvoltage and overcurrent. Our product portfolio covers surge arresters and switching spark gaps, sensors and sensor systems, thermistors, varistors, and a wide range of multilayer ceramic components, including piezo actuators.
SAW components (surface acoustic wave components), integrated radio frequency modules are key components of modern information and communications. They select frequencies and have a crucial impact on signal quality in audio and TV equipment as well as in mobile phones, for example.
