PEMI6QFN/HK,132

Overview

The PEMI6QFN/HK,132 is a Surface Mount Device (SMD) EMI/RFI filter manufactured by NXP USA Inc. It belongs to the RC (Pi) network category and features a 6-channel configuration housed in a 12-XFDFN package. The component provides electromagnetic interference suppression with specific electrical characteristics: resistance of 45 Ohms and total capacitance of 13.5 pF.

Feature Summary

• Provides EMI/RFI filtering through an RC Pi-network topology
• Supports six independent signal channels for multi-line protection
• Designed for surface mount assembly using XFDFN packaging

Applications

• High-speed data line protection
• Portable electronic device interface filtering
• Consumer electronics signal integrity enhancement

Procurement Notes

Verify the exact suffix designation during procurement, as variations such as LC, LT, or CR indicate different resistance and capacitance values within the same family. Confirm RoHS compliance status and ensure the supplier provides official datasheets matching the specific HK variant to avoid functional mismatches due to parameter differences.

Selection Notes

Select this component when a 45-ohm impedance match and low parasitic capacitance are required for high-frequency signal lines. The 12-XFDFN package offers a compact footprint suitable for space-constrained designs. Ensure the application voltage and current ratings align with the system requirements before integration.

Part Context

This part is part of NXP's broader portfolio of passive EMI/RFI filters designed for consumer and industrial applications. Similar variants like PEMI6QFN/LC,132 offer different impedance values, allowing designers to tailor filtering performance to specific bus speeds and noise environments without changing the physical footprint.

Replacement Considerations

Direct substitutes include other NXP variants in the PEMI6QFN series, such as PEMI6QFN/LC,132 or PEMI6QFN/CR,132, provided their specific R and C values meet the circuit design requirements. Cross-brand replacements require careful verification of pinout compatibility and electrical parameters.
