TCM0403S Common-Mode Filter TDK TCM0403S Common-Mode Filter is a thin-film filter with a wide frequency range that can be used for high-speed differential signal interfaces, such as USB 3.0 and DisplayPort. This filter provides EMC suppression by achieving a wide frequency range (6GHz and higher) differential mode transmission while ensuring common-mode impedance with virtually no effect on the high-speed differential transmission line signal. TDK TCM0403S Common-Mode Filter is offered in a 0403 package and operates over a -25°C to +85°C temperature range.
