PEMI8QFN/HP,132

Overview

The PEMI8QFN/HP,132 is an integrated EMI/RFI filter network manufactured by NXP USA Inc. It utilizes a second-order RC (Pi) topology to provide signal conditioning for high-speed data lines. The device features eight independent channels, making it suitable for multi-lane interfaces such as USB and PCIe. Packaged in a compact 16-HXSON surface-mount format with exposed pad, it offers low insertion loss and effective noise suppression. Key electrical characteristics include a nominal resistance of 45 ohms and capacitance of 18.5 pF per channel, ensuring minimal signal distortion while attenuating electromagnetic interference across the operating bandwidth.

Feature Summary

• Integrates eight independent low-pass filter channels within a single compact package
• Employs second-order RC Pi-network topology for enhanced attenuation performance
• Designed specifically for suppressing EMI/RFI on high-speed digital data interfaces
• Features low parasitic capacitance to maintain signal integrity during transmission

Applications

• High-speed serial data line protection for USB 3.0 and USB 2.0 ports
• Signal filtering for PCI Express (PCIe) interconnects
• EMI suppression in mobile devices and consumer electronics
• Noise reduction for HDMI and DisplayPort video interfaces

Procurement Notes

Verify the exact suffix 'HP,132' against the manufacturer's latest datasheet to confirm pinout compatibility and RoHS status. Ensure the selected distributor provides traceability documentation. Check for any recent product change notices that might affect mechanical dimensions or material composition before finalizing procurement orders.

Selection Notes

Select this component when designing circuits requiring multi-channel EMI filtering for differential or single-ended high-speed signals. The 45-ohm resistance and 18.5-pF capacitance values are optimized for impedance matching in standard 50-ohm systems. Consider the 16-HXSON package size if board space is constrained. Validate thermal performance requirements as the exposed pad aids in heat dissipation during operation.

Part Context

This part belongs to NXP's family of passive EMI/RFI filter networks. Similar variants exist with different channel counts, such as the PEMI6QFN series for six-channel applications. These components are designed to complement active drivers and transceivers by providing passive noise filtering without introducing significant latency or power consumption into the system architecture.

Replacement Considerations

Direct substitutes may include other 8-channel RC filter networks from manufacturers like Texas Instruments or Murata. Verify that replacement parts match the 45-ohm resistance and 18.5-pF capacitance specifications. Ensure the alternative package footprint is compatible with existing PCB land patterns or requires re-layout.
