Product Range

The diverse range of TDK Electronics 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 machines, electric railways, wind farms, and photovoltaic power plants, as well as in household appliances, LED lamps, smartphones, notebooks, and entertainment devices. In all these applications, TDK Electronics solutions ensure the supply of power, protect electronic circuits, measure physical values, and ensure their fault-free operation. 


Capacitors are used in all fields of electrical engineering and electronics. They store electric charge or filter currents and voltages. Our portfolio includes aluminum electrolytic, aluminum hybrid polymer, and film capacitors, whose main applications are in power supplies and converters. Power capacitors ensure a stable power supply in electric trains, for example. In addition, power capacitors are the key components for the transmission of high-voltage direct current (HVDC), which enables energy to be transmitted over long distances with minimal loss. 



Inductors fulfill two basic functions of electrical engineering, often simultaneously: the filtering of currents and the storage of electrical energy in a magnetic field. Ferrites, in turn, constitute the core of inductances and they bundle magnetic 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. We also manufacture 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 TDK Electronics portfolio covers 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 (Electrostatic Discharge) protection, and CeraLink capacitors. These components are essential, above all, in vehicles, industrial equipment, and household appliances, but also in power engineering, smartphones, tablets, and wearables. Among our latest product highlights are PowerHap piezo actuators for haptic feedback, CeraPlas for generating 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 in electric mobility applications to monitor electric motors, batteries, and charging electronics. In addition, there are pressure sensors and transmitters that are needed in pneumatic and hydraulic systems – in combustion engines, for example, pressure sensors are indispensable for reducing emissions. Medical technology is another application area, for example in devices for measuring blood pressure or for artificial respiration. Our sensor portfolio is complemented by the Tronics product range of inertial sensors, which can detect acceleration values 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 2024, TDK posted total sales of USD 14.6 billion and employed about 101,000 people worldwide.
