Electronics Power Supply / Management common filters mode noise power reduction tdk thin-filmTDK TCM0403T series noise reduction common mode filters for high-speed differential transmission applications measure 0.45 x 0.3 x 0.23mm. Product’s proprietary fine patterning serves the coil conductor and delivers noise control in high-speed differential transmission, as well as high common mode attenuation.
TCM0403T-200-2P-T210 and TCM0403T-080-2P-T210 common mode filters have a differential insertion loss cut off frequency of 8GHz or higher and can support transfer speeds up to a maximum of 12Gbits per second. Common mode attenuation, which is an important index for noise counter measures, has improved in this series compared to conventional products, reported TDK. TCM0403T-200-2P-T210 provides a common mode attenuation of 42dB at 2.4GHz, and TCM0403T-080-2P-T210 has a high common mode attenuation of 34dB at 5.0GHz.
