Mount Prospect, Ill.TDK Corp. has launched a wide-band thin-film common mode filter for EMI suppression on DisplayPort interfaces.
The filter, TCM1210U-500-2P, works as an EMI countermeasure on high-speed data transmission lines in notebook computers, audiovisual equipment and other electronic devices.
With a measurement of 1.25 mm (L) x 1.0 mm (W) x 0.6 mm (T), this product is designed specifically for suppressing noise on DisplayPort connections, the standard for signal transmission between computers or audiovisual equipment and display monitors at speeds that exceed HDMI (2.25 Gbit/s). A DisplayPort link uses up to four lines, each rated for 2.7 Gbit/s, resulting in a total transfer rate of 10.8 Gbit/s.
With a cutoff frequency of 8.0 GHz, the filter's rating is 2 GHz higher than that of the existing thin-film common mode filter for HDMI (TCM1210H-900-2P). Additionally, the filter has an impedance of 50 ohms (at 100 MHz), a rated current of 100 mA and rated voltage of 10V. As a result, the filter offers effective noise control without degrading the transmission characteristics of high-speed differential transmission line signals.
Pricing: Sample pricing is 100 Yen (approx US$0.92) p/piece.
Availability: Mass production begins in August in Japan.
