TDK TCM0403R miniaturised thin-film common-mode filter
TDK Corporation has expanded its line-up of common-mode filters. The TCM0403R thin-film common-mode filter offers a common-mode attenuation of 27.5 dB at 850 MHz in a 0403 package (0.45 x 0.30 mm).
The footprint of the device is nearly 60% smaller than the existing TCM0605R with the same common-mode attenuation. In addition, the filter features a low insertion height of only 0.23 mm.
With a cut-off frequency of 5 GHz and good common-mode attenuation characteristics in the 500 MHz to 2.4 GHz range, the filter suppresses common-mode noise without distorting high-speed differential signals. It is thus compatible with high-speed interfaces such as MIPI, USB 2.0 and USB 3.0.
The typical DC resistance is 3.5 Ω. As a result, the filter improves the WLAN reception sensitivity in smartphones, conventional mobile phones and other compact portable devices.
