Tiny thin-film common-mode filter from TDK for high-speed data-bus filtering
Date: 28/06/2023
To keep the RF noise out of your high-speed data buses such as USB3.0/3.1/3.2, HDMI2.0/2.1, Display port/Edp, MIPI D-PHY, TDK is offering noise reduction common mode filter. This new filter TCM0403T is very small in size measuring 0.45 x 0.3 x 0.23 mm supporting transfer speeds up to maximum of 12 Gbps. With RF noise everywhere, the RF noise on the data-buses need to be cleaned up for reliable transmission, this filter does that taking less space.
Further information on this product from TDK includes:
The TCM0403T-200-2P-T210 and TCM0403T-080-2P-T210 products in this lineup have a differential insertion loss cutoff frequency of 8 GHz or higher and can support transfer speeds up to a maximum of 12 Gbps. Common mode attenuation, which is an important index for noise countermeasures, has improved in this series compared to conventional products. TCM0403T-200-2P-T210 has a high common mode attenuation of 42 Db at 2.4 GHz, and TCM0403T-080-2P-T210 products has a high common mode attenuation of 34 Db at 5.0 GHz.
The coil conductor pattern is designed using TDK’s proprietary fine patterning, which uses a thin-film method and applies a technology cultivated through the development of TDK's magnetic heads. The implementation of this new world's smallest size common mode filter will support the miniaturization, thinning, and weight reduction of electronic devices.
To control radiation and exogenous noise in the differential transmission lines that are expected to increase in speed in the future, TDK will continue to develop small-sized thin-film common mode filters and provide services contributing to the quality improvement of wireless communication systems.
