PEMI4QFN/RP,132

Overview

The PEMI4QFN/RP,132 is an EMI/RFI filter circuit manufactured by NXP USA Inc. It functions as a passive RC (Pi) low-pass filter network designed for surface-mount applications. The component integrates four channels within an 8-XFDFN package. Key electrical parameters include a resistance of 100 Ohms and a total capacitance of 18.5 pF per channel.

Feature Summary

• Integrates multiple channels into a compact surface-mount footprint
• Provides passive filtering for EMI and RFI suppression
• Designed for signal line protection in electronic circuits

Applications

• LAN interface protection
• PCS signal filtering
• WAN data line conditioning

Procurement Notes

Verify the exact suffix 'RP' against official NXP documentation to confirm the specific capacitance value of 18.5 pF. Ensure the package type matches the required 8-XFDFN form factor. Confirm RoHS compliance status through the manufacturer's current environmental declarations before integration.

Selection Notes

Select this component when a multi-channel RC Pi-filter is required for high-density PCB layouts. The 100 Ohm resistance and 18.5 pF capacitance values are suitable for specific impedance matching and cutoff frequency requirements in digital signal lines. Compare with other PEMI4QFN variants if different capacitance values are needed.

Part Context

This part belongs to the PEMI4QFN family of EMI filters from NXP. Variants such as PEMI4QFN/RE,132 and PEMI4QFN/CT,132 share similar packaging but differ in internal resistor and capacitor values. The family is designed for versatile signal integrity management across various communication interfaces.

Replacement Considerations

Direct substitutes may include other PEMI4QFN variants like PEMI4QFN/RE,132 or PEMI4QFN/RR,132, provided their specific RC values align with the design requirements. Verify pin compatibility and thermal characteristics before substitution.
