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.

Die TDK Corporation hat ihr Spektrum an EPCOS Motor-Entstördrosseln um sechs neue Typen erweitert. Um eine hohe Designflexibilität zu erreichen, sind die Drosseln in drei verschiedenen Bauformen mit unterschiedlichen Nennströmen und Induktivitätswerten verfügbar.

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.

The radiation noise countermeasure in power lines of in-vehicle electronic equipment provided by TDK's YFF series 3-terminal filters is introduced in the following, based on case examples of evaluation and measurement.

A capacitor is the most basic electronic component for noise suppression in power lines of electronic equipment. A capacitor has a characteristic that, the higher the frequency, the easier the current passes through it, and when a power line is connected to the ground through a capacitor, high-frequency noise is bypassed to the ground and separated.

December 2018 : ACT45L-201-2P-TL000 listed on this page is a not-recommended for new design.As sensor and camera based devices become more and more common in automobiles, Ethernet technology has been introduced at a rapid pace as automotive LAN systems for advanced multimedia and data communication devices. TDK developed the ACT45L type of common mode filters for Ethernet, which has achieved excellent noise suppression characteristics in a small and low-profile form.

The interior of an automobile is an extremely noisy electrical environment, and common mode filters are therefore used as an EMC counter-measure in automotive LANs. In order to respond to the market need to conserve space in ECU circuit boards, TDK has developed ACT1210 type common mode filters for automotive LANs, which are small and high-performance filters that radically reduce mounting area space.
