PEMI4QFN/HM,132

Overview

The PEMI4QFN/HM,132 is a Surface Mount Device (SMD) EMI/RFI filter belonging to the RC(PI) network category. It features an impedance of 45 Ohms and a capacitance of 16 pF. The component utilizes an 8-XFDFN package with dimensions of 1.70mm length, 1.20mm width, and 0.50mm height.

Feature Summary

• Integrates passive RC(PI) filtering topology for signal integrity
• Designed for effective EMI and RFI suppression in compact layouts
• Supports high-density surface mount assembly processes

Applications

• Portable electronic devices requiring noise reduction
• High-speed data line protection circuits
• Consumer electronics signal conditioning

Procurement Notes

Verify the specific suffix HM against official NXP documentation to confirm the 45 Ohm/16pF configuration. Ensure the XFDFN-8 package footprint matches the design layout. Confirm RoHS compliance status through the manufacturer's environmental declaration before integration.

Selection Notes

Select this component when a low-profile PI-filter is required for EMI suppression on sensitive lines. The 45 Ohm resistance and 16 pF capacitance values define the cutoff characteristics. Compare against other PEMI4QFN variants if different impedance or capacitance values are needed for the target application frequency.

Part Context

This part belongs to the PEMIxQFN family of passive filter networks from NXP USA Inc. These components are engineered for space-constrained applications where standard through-hole filters cannot fit. The family offers various impedance and capacitance combinations within the same small form factor.

Replacement Considerations

PEMI4QFN/RR,132 is listed as a related variant in distributor databases. Verify electrical parameters such as resistance and capacitance values differ between models before substitution.
