Along with the increasingly high speed and high functionality of in-vehicle LANs, in LVDS transmissions in-vehicle camera systems, PoC (Power over Coax) which placed signal and power source on top of each other in the single line are becoming increasingly advanced. Power inductor ADL3225V type guarantees transmission quality while saving space.

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.

TDK has developed TCM0403R common mode filters, which have realized a significant size reduction compared to the existing thin-film common mode filters. This size reduction was made possible through the application of unique thin-film processing techniques, developed for HDD heads. These filters are ideal as a noise suppression measure in mobile devices such as smartphones and tablets, for which conservation of space is demanded.

The number of smartphones and other mobile devices that are compatible with NFC (Near Field Communication) is increasing. Thanks to the adoption of a newly-developed low-loss ferrite material, TDK’s MLJ series multilayer ferrite coils now offer improved communication properties which are ideal for NFC-equipped devices, while featuring compact package sizes.

Switching to MLCCs provides various benefits such as a small size due to the miniature and low-profile form factor, ripple control, improved reliability and a long life.

TDK’s CLF-NI-D series wire-wound power inductors are products that benefit from the use of highly heat resistant materials, unique structural designs and methods. The products offer high reliability across a wide range of temperatures from -55°C to +150°C. They are tolerant of the extreme environment found in the engine bay of automobiles, even under the most severe usage conditions.

TDK offers special types of MLCC products with redundancy design, in order to avoid short circuit failures and improve the reliability of equipment. Please select products that suit your purposes and use them to improve the reliability of your products.
