EMC Components ESD Notch Filters Noise Suppression Filters Applications & Cases Jul. 2015 [Application Note] Ultra-small common mode filter package can reduce footprint in half 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.
