PEMI6QFN/HP,132

Overview

The PEMI6QFN/HP,132 is a six-channel RC (Pi) EMI filter manufactured by NXP USA Inc. It features a second-order low-pass configuration designed for suppressing electromagnetic interference in high-speed data lines. The component integrates resistors and capacitors within a compact 12-XFDFN surface-mount package. Key electrical parameters include a resistance value of 45 Ohms per channel and a total capacitance of 18.5 pF. This design supports efficient noise attenuation while maintaining signal integrity in dense circuit layouts.

Feature Summary

• Six-channel architecture for multi-line signal filtering
• RC Pi-network topology for second-order low-pass performance
• Compact XFDFN surface-mount package for space-constrained designs

Applications

• High-speed data line protection
• USB interface noise suppression
• HDMI signal integrity enhancement
• General purpose EMI/RFI mitigation in consumer electronics

Procurement Notes

Verify the specific suffix HP against the manufacturer's current datasheet to confirm exact R and C values. Ensure the 12-XFDFN package dimensions match your PCB footprint requirements. Confirm RoHS compliance status if required by your manufacturing standards. Cross-reference the part number with official NXP documentation to avoid confusion with similar variants like CR or HE.

Selection Notes

Select this component when multiple differential or single-ended lines require simultaneous filtering in a small area. The 45 Ohm resistance and 18.5 pF total capacitance offer a balanced trade-off between attenuation and signal loss. Consider the XFDFN package size relative to available board space. Evaluate insertion loss characteristics against your specific frequency requirements before finalizing the design.

Part Context

This part belongs to the PEMI6QFN family of integrated EMI filters from NXP. These components consolidate discrete passive elements into a single monolithic structure. The QFN/LK or XFDFN packaging options provide thermal and mechanical advantages over traditional discrete solutions. The family targets applications requiring robust noise suppression without increasing component count or assembly complexity.

Replacement Considerations

Direct substitutes may include other PEMI6QFN variants such as PEMI6QFN/CR,132 or PEMI6QFN/HE,132, provided their specific R and C values align with the circuit design. Verify that the replacement maintains the same 12-XFDFN package outline to ensure mechanical compatibility. Check datasheets for differences in cutoff frequencies and power handling capabilities.
