PEMI4QFN/BYP,132

Overview

The PEMI4QFN/BYP,132 is a passive RC (Pi) EMI filter circuit manufactured by NXP USA Inc. It features a second-order low-pass configuration with four independent channels. The component integrates Electrostatic Discharge (ESD) protection capabilities within the filter network. It utilizes an 8-XFDFN surface-mount package for compact integration into high-density printed circuit boards.

Feature Summary

• Integrates RC low-pass filtering with ESD protection in a single package
• Provides four-channel signal conditioning for multiple data lines
• Designed for high-frequency noise suppression in sensitive interfaces

Applications

• High-speed interface line protection
• USB port EMI filtering and ESD protection
• HDMI or DisplayPort signal integrity enhancement
• Mobile device peripheral interface filtering

Procurement Notes

Verify the specific suffix 'BYP' to confirm the integrated ESD protection variant, as other suffixes in the PEMI4QFN family may lack this feature. Confirm the '132' tape-and-reel quantity matches your assembly requirements. Check current lifecycle status as NXP frequently updates component availability for passive filter families.

Selection Notes

Select this component when simultaneous EMI attenuation and ESD robustness are required on multiple differential or single-ended lines. Compare channel count and cutoff frequency against system specifications. Ensure the XFDFN footprint aligns with existing PCB layout constraints compared to standard QFN packages.

Part Context

This part belongs to the PEMIxQFN/2STD family of passive filter networks from NXP Semiconductors. The family includes various configurations with different resistor values and capacitance levels tailored for specific impedance matching and filtering needs across consumer electronics and industrial applications.

Replacement Considerations

Direct substitutes include other PEMI4QFN variants such as PEMI4QFN/RR,132 or PEMI4QFN/LK,132, provided their electrical parameters match the design requirements. Verify that alternative parts offer equivalent ESD protection levels if that feature is critical.
