PEMI8QFN/LR,132

Overview

The PEMI8QFN/LR,132 is an RC (Pi) EMI filter manufactured by NXP USA Inc. It features a second-order low-pass configuration with eight channels. The component utilizes a 65 Ohm resistance and 21 pF total capacitance per channel. It is housed in a 16-XFDFN exposed pad package designed for surface mount technology.

Feature Summary

• Eight-channel signal filtering capability
• RC Pi-network topology for EMI suppression
• Surface mount design with exposed pad

Applications

• High-speed data line protection
• USB interface noise reduction
• HDMI signal integrity enhancement

Procurement Notes

Verify the specific suffix LR against the official NXP datasheet to confirm the 65 Ohm/21pF specification. Ensure the XFDFN package dimensions match the PCB footprint requirements. Confirm RoHS compliance status through the manufacturer's current documentation before finalizing procurement orders.

Selection Notes

Select this component when eight-channel simultaneous filtering is required on high-speed interfaces. The RC Pi structure offers effective attenuation without significant signal distortion. Consider the thermal performance of the exposed pad for heat dissipation in dense layouts.

Part Context

This part belongs to the PEMIxQFN family of integrated EMI filters. These components are designed to replace discrete LC networks, saving board space. The family includes variants with different resistance and capacitance values to suit various impedance matching requirements.

Replacement Considerations

Check for direct substitutes within the PEMI series with compatible pinouts. Verify that alternative parts maintain the same 16-XFDFN package and electrical characteristics to ensure mechanical and functional compatibility.
