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).

Electronic control units (ECUs) for advanced driver assistance systems are consuming more power, and the latest trend is toward ECU integration—installing an ECU close to the engine room or other working part. For these reasons, the number of electronic devices and components built into cars these days is on the rise, and the reliability of the electronic components used in the electronics is having a growing impact on the reliability of the vehicle overall.

A PoC filter consisting of one or more inductors and chip beads is used on the circuit side to separate the signal and the power supply current. This is important in terms of maintaining communication quality. The PoC filter therefore requires inductors that realize high impedance for AC components over a wide bandwidth range from low to high frequencies.

Countermeasures which implement combinations of TDK's noise suppression filters and ESD Notch Filters can not only demonstrate outstanding effectiveness at suppressing TDMA noise with no effect on signals, but can also provide a variety of other benefits such as improving cellular or Wi-Fi communication reception sensitivity, and providing countermeasures against ESD (electrostatic discharge).
