PCMF3USB3SZ

Common Mode Chokes Overview

The PCMF3USB3SZ is a common-mode EMI filter circuit manufactured by Nexperia, designed for differential signal channels with integrated electrostatic discharge (ESD) protection. It utilizes a WLCSP-15 package and operates within a temperature range of -40°C to +85°C. The component features a typical DC resistance (DCR) of 3 Ohms per line. It provides robust protection against ESD events, supporting contact discharge voltages up to 15 kV and air gap discharge voltages up to 15 kV. This device integrates filtering and suppression functions into a compact surface-mount form factor.

Common Mode Chokes Procurement Notes

Verify the specific suffix 'SZ' against the official Nexperia datasheet to confirm packaging configuration and tape-and-reel specifications. Ensure compatibility with automated pick-and-place equipment requirements for the WLCSP-15 footprint. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm current production status and availability constraints.

Common Mode Chokes Selection Notes

Select this component when simultaneous EMI attenuation and ESD protection are required for USB 3.0 differential pairs. The low capacitance and integrated design reduce board space compared to discrete solutions. Verify that the 3 Ohm DCR meets the impedance matching requirements of the target transmission line. Confirm thermal performance aligns with the operating environment limits.
