NFC is a function that can perform data communications and authentication when two NFC-compatible devices are brought close together, and adoption in smart phones has been growing rapidly in recent years. Increased use in peripheral devices including wearable terminals, such as smart watches, has also been observed. NFC is used in many situations including cashless payment and authentication of connections with peripheral devices, and it is expected to be used for even more diverse applications as we move towards a touchless society. This article introduces the main components used in NFC circuits: NFC antenna, magnetic sheet, LC filter inductor, single-end circuit balun, and electric double-layer capacitor (EDLC/supercapacitor).

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.
