The new TCM1210U500-2P from TDK Corporation is a wideband, thin-film, common-mode filter for EMI suppression in DisplayPort interfaces. This new filter works as an EMI countermeasure on high-speed data transmission lines in notebook computers, audio-visual equipment, and other electronic devices. With dimensions of 1.2 mm (L) x 1.0 mm (W) x 0.6 mm (H), this product has been crafted expressly for suppressing noise on DisplayPort connections, a new standard for signal transmission between computers and audio-visual equipment and display monitors at speeds that exceed even HDMI (2.25 Gbits/s). A DisplayPort link uses up to four lines, each rated for 2.7 Gbits/s for a total transfer rate of 10.8 Gbits/s.Utilizing TDK’s proprietary thin-film magnetic head technology, this device has a cut-off frequency of 8.0 GHz, an impedance of 50 Ω (at 100 MHz), a rated current of 100 mA, and a rated voltage of 10 V. Consequently, the TCM1210U500-2P offers effective noise control without degrading the outstanding transmission characteristics of high-speed differential transmission line signals.
