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.
TDK has been offering pouch-type EDLCs, and has developed a new ultra-thin EDLC, with a thickness of 0.45mm (max.) that can be stored inside an IC card. It realizes battery-less smart cards equipped with a display, and is suitable for secondary power supplies for wearable devices or IoT devices.
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.
