PCMF2USB3BA/CZ is listed in the Common Mode Chokes range at ChipApex. The manufacturer field lists Nexperia USA Inc.. Its product description is CMC 4LN SMD ESD. Review the specifications below when checking this part for your BOM.
The PCMF2USB3BA/CZ is a common mode EMI filter circuit manufactured by Nexperia, designed for high-speed signal lines. It integrates electrostatic discharge (ESD) protection within a WLCSP-10 package. Key electrical parameters include a cutoff frequency of 10 GHz, capacitance of 300 fF, and resistance of 2.2 ohms. The device supports a voltage rating of 9 V and a current rating of 7.5 A. It features two channels and utilizes SMD/SMT termination.
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status via the official datasheet. Check for limited supply conditions as indicated by current market availability. Ensure storage and handling procedures meet ESD safety standards to preserve device integrity before installation.
Select this component when designing circuits requiring combined EMI filtering and ESD protection for differential pairs. The WLCSP-10 form factor suits space-constrained layouts. Evaluate the 10 GHz cutoff frequency against target signal bandwidths. Consider the 2.2 ohm resistance value for impedance matching requirements in high-speed transmission lines.
This part belongs to Nexperia's portfolio of integrated passive devices combining filtering and protection functions. It addresses the need for compact solutions in modern electronics where board real estate is limited. The integration reduces component count compared to discrete filter and TVS diode combinations.
PCMF2USB3B/CZ is a documented substitute variant within the same product family.
