• Integrated EMI and RFI suppression
• Surface mount design for compact footprints

Applications

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

Procurement Notes

Verify the specific suffix '132' to ensure correct tape-and-reel packaging configuration. Confirm the manufacturer is NXP Semiconductors or NXP USA Inc. Check for obsolescence notices as some variants may be discontinued. Ensure the part matches the 8-XFDFN package outline for PCB compatibility.

Selection Notes

Select this component when four-channel low-pass filtering is required for differential or single-ended lines. The 20-ohm resistance and 23-pF capacitance values are optimized for specific impedance matching and cutoff frequencies. Compare against other PEMI4QFN variants like PEMI4QFN/RR if different electrical characteristics are needed.

Part Context

This part belongs to the PEMI4QFN family of EMI filters from NXP. These components integrate resistors and capacitors into a single SMD package to reduce board space. The family includes various configurations with different resistance and capacitance values tailored for USB, HDMI, and other high-speed interfaces.

Replacement Considerations

Direct substitutes include other PEMI4QFN variants such as PEMI4QFN/RR,132 or PEMI4QFN/LK,132, provided their electrical parameters match the circuit requirements. Verify pinout compatibility before substitution.
