TDK 0605 TCM Series Wire Wound Chokes. TCM series are thin-film common mode filters with a wide frequency range that can be used for high-speed differential signal interfaces such as USB3.0 and DisplayPort. Features and Benefits:. TCM-S has EMC suppression by achieving wide frequency range 6 GHz and higher (TCM-G cut-off frequency of 3 GHz or higher) differential mode transmission while ensuring common mode impedance with virtually no effect on the high-speed differential transmission line signal Applications in noise countermeasure for high-speed differential interfaces (USB2.0, LVDS, MIPI, etc.) for mobile devices and general consumer products such as smartphones, tablets, digital cameras and portable music players.
