PCMF3HDMI14SZ

Overview

The PCMF3HDMI14SZ is an LC EMI filter manufactured by NXP USA Inc., designed for high-speed signal integrity. It features a second-order low-pass configuration with three channels, providing effective noise suppression in compact form factors. The component integrates specific electrical characteristics including a resistance of 3 Ohms and capacitance of 0.25 pF per channel, optimized for frequencies up to 6 GHz. Packaged in a 15-UFBGA or WLCSP surface-mount format, it supports efficient PCB layout while maintaining robust electromagnetic interference protection for sensitive digital interfaces.

Feature Summary

• Integrates a second-order low-pass LC filter topology for enhanced attenuation performance
• Provides dedicated common-mode noise suppression across three independent signal channels
• Utilizes a wafer-level chip-scale package (WLCSP) for minimal board space consumption

Applications

• High-definition multimedia interface (HDMI) signal line protection
• Display port (DP) data line filtering
• USB 3.0 and Thunderbolt interface noise suppression

Procurement Notes

Verify the manufacturer designation carefully, as sources may list both NXP USA Inc. and Nexperia USA Inc. due to corporate restructuring history. Confirm the specific suffix 'SZ' matches your required tape-and-reel or bulk packaging specifications. Ensure compatibility with RoHS compliance standards if required for your manufacturing process. Cross-reference the datasheet version to confirm pinout consistency with existing designs.

Selection Notes

Select this component when space constraints preclude discrete LC networks. The integrated design simplifies layout compared to individual components. Verify that the 3 Ohm series resistance aligns with the impedance requirements of the connected transmission lines. Ensure the operating frequency range covers the harmonic content of the signals being filtered without introducing excessive insertion loss.

Part Context

This component belongs to the PCM-F3 family of EMI filters specifically engineered for HDMI and other high-bandwidth digital video interfaces. It addresses the growing need for compact, integrated solutions in mobile devices and consumer electronics where space is limited. The technology represents a shift from discrete filtering components to monolithic integrated structures for improved reliability and assembly efficiency.

Replacement Considerations

Public documentation references the PCMF2HDMI14SZ as a related variant within the same product family. Verify channel count and electrical parameters before substitution, as differences between models may exist. No other direct substitute part numbers are confirmed in available public records.
