Small sized common-mode noise filter for MIPI, USB 2.0/3.0 interfaces
TDK Corporation has developed what it claims as the world’s smallest common-mode filter, which measures in at only 0.45 mm x 0.30 mm x 0.23 mm and is 75 percent smaller than current 0806 filters (IEC). TCM0403S-350-2Poffers high cutoff frequency of 7.0 GHz the filter suppresses common-mode noise without distorting high-speed differential signals. It is thus compatible with various high-speed interface such as MIPI, USB 2.0, and USB 3.0. The excellent common-mode attenuation at 2.4 GHz improves the wireless LAN reception sensitivity in smartphones, conventional mobile phones and other compact portable devices. Mass production will begin in July 2012.
TDK has reduced the size of this filter using thin-film patterning technology combined with compact, high-precision coil pattern and terminal formation processes. The new filter supports the high-density mounting of electronic components.
