PCMF2USB3B/CZ

Common Mode Chokes Overview

The PCMF2USB3B/CZ is a bidirectional common mode EMI filter with integrated ESD protection, manufactured by Nexperia. It features a WLCSP-10 package and supports two channels (four lines). The device operates within a temperature range of -40 °C to +85 °C or +125 °C depending on the specific datasheet reference. Key electrical parameters include a maximum input voltage of 4 V and a typical DC resistance (DCR) of 2.6 Ω to 3 Ω. The component is designed for high-current applications, supporting up to 9.5 A.

Common Mode Chokes Feature Summary

• Integrates TrEOS ESD protection technology specifically optimized for USB Type-C interfaces.
• Provides bidirectional common mode filtering to suppress electromagnetic interference in data lines.
• Utilizes a compact WLCSP-10 surface mount package for space-constrained designs.

Common Mode Chokes Applications

• USB Type-C port protection and signal conditioning
• High-speed data line EMI suppression
• ESD protection for consumer electronics interfaces

Common Mode Chokes Procurement Notes

Verify current availability status as supply may be limited or subject to special order constraints. Confirm the specific operating temperature grade (-40 °C to +85 °C vs. +125 °C) required for your application against the latest official datasheet. Ensure compatibility with WLCSP-10 footprint requirements during PCB layout. Check for any recent product change notices regarding packaging or labeling updates.

Common Mode Chokes Selection Notes

Select this component when designing USB Type-C circuits requiring combined EMI filtering and ESD protection in a minimal footprint. The low DCR value supports high current transmission necessary for power delivery standards. Verify that the 4 V input rating aligns with the target bus voltage levels. Consider the thermal performance limits defined in the datasheet for the intended operating environment.

Common Mode Chokes Part Context

This part belongs to the PCM family of common mode filters from Nexperia. It is distinct from similar models like PCMF2USB3S/CZ or PCMF2DFN1XL by its specific WLCSP-10 packaging and integrated ESD characteristics tailored for USB applications. It serves as a specialized solution for protecting high-speed data interfaces against noise and electrostatic discharge events.

Common Mode Chokes Replacement Considerations

PCMF2USB3SZ is listed as a similar alternative in some distributor databases. Verify pinout compatibility and exact electrical specifications before substitution. Other family members such as PCMF2DFN1XL differ significantly in package type and line count.
