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 ACM series of common mode filters and chokes, and chip varistors and ceramic transient voltage suppressors used for surge protection.

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.

The methods of use of automobiles will change substantially in the future including autonomous driving and car sharing services, and the human machine interface (HMI) between drivers and their cars will also completely change.
The automobile industry is developing the digital cockpit in pursuit of an HMI that will provide safety and reassurance while freeing drivers from the burdens of driving and allow time to be used meaningfully and in comfort.
Below is an introduction to TDK product and technologies that enhance the value of the digital cockpit with the aim of achieving an HMI that ensures and enhance safety and reassurance through the driver's senses.

The evolution of sensing technology and communication network contribute to the realization of Autonomous driving society and its growth. In association with full-scale expansion of the "5G service" next-generation wireless communication standard, great attention is being placed on wireless technology intended for "vehicle-to-vehicle and infrastructure-to-vehicle communication" (V2X) to communicate data between automobiles and their surroundings. While the TDK Group can offer a lineup of various electronic components for V2X, this article introduces a selection of IMU (Inertial Measurement Unit) and high-frequency products for Telematics Control Units (TCUs).

The demand for high-speed automotive onboard interfaces is increasing, with a view towards supporting driving safety, reducing the environmental load, and improving comfort. For bidirectional communication, the automotive Ethernet format is commonly used, while LVDS is the choice for one-way communication. With LVDS (Low Voltage Differential Signaling), the preferred approach is to also adopt the PoC (Power over Coax) method that enables transmission of the signal and power supply over a single coaxial cable, thereby reducing the weight of wire harnesses in the car. This page describes usage examples and effects of inductors and chip beads specifically recommended for PoC filter applications.
