With the spread of cloud computing and smartphones and the launch of 5G in 2020, the amount of data that moves on the internet is increasing as high-volume video and game data is added to existing documents, images, and sound data.
In addition, technologies are evolving, exemplified by AI, and a digital transformation (DX) is taking place as a result of the use of big data and the internet of things (IoT). To support these advances, however, large numbers of high-performance servers that can process large volumes of data will be needed. In conjunction with the increased performance of processors and various types of ICs, higher clock speeds of power supply ICs on server boards, high current power saving, miniaturization, noise countermeasures in data lines, and surge countermeasures have become urgent issues. Here, we introduce TDK products for addressing and solving these problems including the VLBU series of ferrite power inductors compatible with the high-efficiency needs of VR13 and VR14 applications, the FS series of DC-DC converters with embedded μPOL™, solutions using the ALT series of pulse transformers and ALC series of common mode filters and chokes, and chip varistors and ceramic transient voltage suppressors used for surge protection.

Haptic devices are starting to be used for applications such as industrial or automotive monitors, displays on white goods such as washing machines, etc. However, these devices are also suitable for smartphones, notebook computers, and other ICT products.
TDK offers haptic device products utilizing the piezoelectric effect.

Automobiles are entering a period of change, and technological innovation supporting electrification and its widespread adoption are becoming important topics.
At the same time, measures to reduce CO2 and exhaust emissions by addressing environmental issues require efforts to develop engines with higher efficiency.
In this article, we present TDK temperature sensors (NTC thermistors) and pressure sensor transmitter/pressure sensor die products that are essential for enhancing engine intake and exhaust performance in order to contribute to the resolution of these issues.

The evolution of sensing technology and communication network contribute to the realization of an Autonomous driving society and its growth. Ultrasonic parking assistant is a key sensor for automated driving and parking functions. Ultrasonic parking sensors were in use in Europe long before debate on automated driving became active. TDK has for many years supplied Piezo Disks and ultrasonic driver transformers for use with ultrasonic parking sensors. TDK also developed a multilayer ceramic chip capacitor that exhibits attenuating capacitance (ZL characteristics) under high-temperature environments that is suitable for resonant circuits with Piezo Disk. This article presents Piezo Disk, ultrasonic driver transformers, and MLCC with ZL characteristics.

As the electrification of automobiles advances, power consumption control is becoming an increasingly important factor. LED Lighting Technology design reduces power consumption, increases lifecycle, offers design freedom and overall control. It is now used in Automotive functions including headlights and interior lighting. The TDK Group offers an extensive lineup of power inductors for use in LED drivers optimized for different systems including step-up, step-down, and step-up/step-down types.
