NFC ist eine Abkürzung für Near Field Communication; es handelt sich um eine Art drahtloser Kommunikation mit kurzer Reichweite.
NFC ist eine Funktion, die Datenkommunikation und Authentisierung durchführen kann, wenn zwei NFC-kompatible Geräte in die Nähe zueinander gebracht werden, und ihr Einsatz in Smartphones hat in den letzten Jahren stark zugenommen.
Auch in Peripheriegeräten einschließlich tragbarer Endgeräte, wie z.B. Smart-Uhren, ist ein zunehmender Einsatz von NFC zu beobachten.
NFC wird in vielen Situationen eingesetzt, u.a. beim bargeldlosen Bezahlen und bei der Authentifizierung von Verbindungen mit Peripheriegeräten, und es wird erwartet, dass es auf dem Weg zu einer berührungslosen Gesellschaft für noch vielfältigere Anwendungen eingesetzt werden wird.
Dieser Artikel stellt die wichtigsten Komponenten vor, die in NFC-Schaltungen verwendet werden: NFC-Antenne, Magnetblech, LC-Filterinduktivität, Ein-End-Schaltungsbalun und elektrischer Doppelschichtkondensator (EDLC/Superkondensator).

Automakers are incorporating more multifunctional capabilities into automobiles as they seek to make autonomous driving a reality. 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.

With the increasing speed and sophistication of interfaces in cars, the PoC (Power over Coax) approach is gaining in popularity, as it allows superimposing signals and power in one coaxial cable, for example for LVDS based automotive camera systems. 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.

This is an introduction to our services for technical support which utilize PI simulations to lower the impedance in power-supply lines and reduce the quantity of required decoupling capacitors, by replacing 2-terminal MLCCs with low-ESL capacitors. We hope they will be of use to you in the increasingly severe field of impedance optimized power-supply line design, and in applications for decoupling capacitor compositions and board design techniques, which are continuing to grow in importance.

In addition to explaining the characteristics of C0G MLCCs with high withstand voltage, this section focuses on the advantages of replacing the film capacitors used in EV wireless power transfer systems.

This section mainly explains the advantages of using MLCCs to replace film capacitors in the onboard chargers (OBC) of plug-in charging systems.

In recent years, there have been remarkable increases in withstand voltage and capacitance in MLCCs (multilayer ceramic chip capacitors) for temperature compensation (type 1). In particular, even in fields where film capacitors have traditionally been used, resonance circuits for example, replacement with MLCC is now possible.

This article introduces some causes of and effective measures against acoustic noise in power inductors, which are main components in power circuits of devices such as DC-DC converters.

The shunt-through connection is a mounting method in which a component is connected in parallel with the power line, and produces an excellent effect for decoupling of the power line. This article will explain each mounting method and their advantages in detail.

The YFF-AC/AH series 3-terminal feed-through filters offer excellent performance for decoupling of the power lines of automotive electronics.
