COMMON-MODE FILTERS FOR HIGH-SPEED DIFFERENTIAL SIGNAL LINES
TDK's family of SMD common-mode filters!
TDK's TCM series offers a variety of different types to suit all high-speed interface applications (IEEE1394 or USB 2.0). The available filters range in size from 1005 (1.0mm x 0.5mm) to 2010 (2.0mm x 1.0mm). By providing wide bandwidth (cutoff frequency: 3GHz) for differential mode (symmetrical interference), TCM series filters have almost no effect on high-speed differential signals and can suppress radiated emissions.
