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.

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.

This atricle introduces major causes and countermeasures of solder crack in MLCCs (Multilayer Ceramic Chip Capacitors).

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.

Conventional devices with hand-laid windings suffer from various problems such as uneven characteristics due to manufacturing tolerances. By contrast, the new pulse transformers from TDK offer excellent uniformity and provide comparable performance as existing products at a much smaller footprint. The ALT series is bound to become a new reference in this field.
