Common mode filters
The PCMFxUSB3BA/C common mode filter (choke)/ ESD protection combination is the market’s fastest, according to manufacturer Nexperia.

The device features the industry’s widest differential passband of up to 10 GHz 3dB frequency and a very high surge robustness of up to 7.5 A 8/20 µs. It is designed to suppress common mode and single-ended noise while minimizing the impact on the signal integrity of extremely fast data lines. Developed to meet the requirements of Super Speed USB applications, the new devices provide effective 1, 2 & 3 line pair protection (Tx +/-, Rx +/-, D +/-) and filtering. Proven for 10 Gbps communications line protection, the filter’s system-level robustness exceeds the IEC 61000-4-2 level 4, suiting them for use with sensitive SoCs. The solution also minimizes reflections when compared to a discrete design. The integration of Nexperia’s TrEOS technology results in low clamping and high robustness.
