NFC stands for Near Field Communication, a type of short-range wireless communication.
Devices equipped with NFC can perform data transmission and authentication simply by being brought close to each other. This feature is rapidly being integrated into smartphones in recent times.
Additionally, its implementation is expanding to peripheral devices like wearable devices such as smartwatches.
NFC is widely used in cashless payment transactions and for connecting and authenticating peripheral devices. It holds the potential for diverse applications in realizing a touchless society.
This article introduces the main components used in NFC circuits, including NFC antennas, magnetic sheets, inductors for LC filters, and baluns for single-ended circuits.

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).

TDK's ANT series ceramic chip antennas feature compact and low profile designs utilizing low temperature co-fired ceramic technology (LTCC). Even with their small size and thin profile, TDK antennas maintain high performance and reliability, all with the industry's smallest "keep-out" area on the PCB which enable ease of PCB design and revision at each development stage.
