PEMI6QFN/WM,132

Overview

The PEMI6QFN/WM,132 is a second-order low-pass RC (Pi) EMI filter manufactured by NXP USA Inc. It features six independent channels designed for signal line filtering applications. The component utilizes an XFDFN package with twelve exposed pads to ensure effective thermal dissipation and mechanical stability. Key electrical parameters include a resistance value of 200 Ohms per channel and a total capacitance of 16 picofarads distributed across the network. This configuration provides efficient attenuation of high-frequency noise while maintaining signal integrity in sensitive digital interfaces.

Feature Summary

• Six-channel architecture for simultaneous multi-line noise suppression
• RC Pi-network topology for second-order low-pass filtering performance
• Compact surface-mount design suitable for space-constrained PCB layouts

Applications

• Local Area Network (LAN) interface protection
• Personal Computer (PC) peripheral signal lines
• Wide Area Network (WAN) communication ports

Procurement Notes

Verify the specific suffix code against official NXP documentation to confirm pinout and electrical characteristics. Ensure the ordering part number matches the required package variant. Cross-reference datasheets for impedance matching requirements. Confirm RoHS compliance status through manufacturer certificates. Validate that the supplier provides genuine components with traceable origin records.

Selection Notes

Select this component when multiple differential or single-ended lines require common-mode noise reduction. The 200-ohm resistance offers a balance between insertion loss and signal attenuation. Consider the 16pF total capacitance impact on signal rise times. Evaluate the XFDFN package dimensions against available board real estate. Compare performance against LC filters if higher attenuation at lower frequencies is required.

Part Context

This device belongs to the PEMI series of integrated EMI filters from NXP. These components are engineered to replace discrete resistor and capacitor networks. They provide a standardized solution for EMC compliance in consumer electronics. The series includes various channel counts and package options to suit different interface densities.

Replacement Considerations

Check for direct substitutes within the PEMI family such as PEMI6QFN/LK,132 or PEMI6QFN/LT,132. Verify compatibility regarding channel count and package footprint. Ensure equivalent electrical parameters before substitution. Consult NXP documentation for cross-reference lists.
