Product Range

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 machines and in electric railways, wind farms and photovoltaic plants, as well as in domestic appliances, LED lamps, smartphones, notebooks and consumer electronics. In all these applications TDK Electronics 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 or filter currents and voltages. The portfolio includes aluminum electrolytic, aluminum hybrid polymer 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. TDK Electronics also manufactures components that ensure electromagnetic compatibility (EMC) and, consequently, the fault-free operation of all types of electronic equipment.

Piezo and protection 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 CeraDiode® varistors, the extremely thin CeraPad® substrate with integrated ESD protection, 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. Among the latest product highlights are PowerHap™ piezo actuators with haptic feedback, CeraPlas™ for the generation of cold plasma, and CeraCharge™, the world’s first rechargeable solid-state SMD battery.

Sensors and sensor systems

Sensors and sensor systems include temperature sensors, which, for example, are used to measure temperature in vehicles with combustion engines to ensure the engine can be run at the optimum operating point. These sensors are also required in electric mobility applications, for example to measure the temperature of batteries and charging electronics. 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. Pressure sensors are also vital for reducing emissions in combustion engine vehicles. One further field of application is medical technology, such as the machines for measuring blood pressure or for artificial respiration. The Tronics product range perfectly complements the portfolio of sensors. This family consists primarily of inertial sensors that, among other things, are able to sense acceleration and tilt angles.

TDK Group

TDK Corporation is a world leader in electronic solutions for the smart society based in Tokyo, Japan. Built on a foundation of material sciences mastery, TDK welcomes societal transformation by resolutely remaining at the forefront of technological evolution and deliberately “Attracting Tomorrow.” It was established in 1935 to commercialize ferrite, a key material in electronic and magnetic products. TDK's comprehensive, innovation-driven portfolio features passive components such as ceramic, aluminum electrolytic and film capacitors, as well as magnetics, high-frequency, and piezo and protection devices. The product spectrum also includes sensors and sensor systems such as temperature and pressure, magnetic, and MEMS sensors. In addition, TDK provides power supplies and energy devices, magnetic heads and more. These products are marketed under the product brands TDK, EPCOS, InvenSense, Micronas, Tronics and TDK-Lambda.

TDK focuses on demanding markets in automotive, industrial and consumer electronics, and information and communication technology. The company has a network of design and manufacturing locations and sales offices in Asia, Europe, and in North and South America. In fiscal 2022, TDK posted total sales of USD 15.6 billion and employed about 117,000 people worldwide.
