PEMI4QFN/WE,132

Overview

The PEMI4QFN/WE,132 is a passive EMI filter circuit manufactured by NXP USA Inc. It features an RC Pi network configuration designed for surface mount applications. The device provides four independent channels of filtering within an 8-XFDFN package. Key electrical parameters include a resistance value of 200 Ohms and a total capacitance of 8.5 pF per channel. This component functions as a second-order low-pass filter to suppress electromagnetic interference in high-speed data lines.

Feature Summary

• Integrates four-channel RC Pi filter networks for multi-line signal protection
• Provides second-order low-pass attenuation characteristics for EMI suppression
• Designed with integrated ESD protection capabilities for robust signal integrity

Applications

• Local Area Network (LAN) interface protection
• Personal Computer System (PCS) data line filtering
• Wide Area Network (WAN) signal conditioning

Procurement Notes

Verify the specific suffix '132' corresponds to the required tape-and-reel packaging format from official NXP documentation. Confirm that the 200 Ohm resistance and 8.5 pF capacitance values align with the target circuit design requirements before procurement. Ensure the 8-XFDFN package dimensions match the PCB footprint specifications.

Selection Notes

Select this component when designing circuits requiring multi-channel EMI filtering for high-speed digital interfaces. The choice depends on the need for integrated ESD protection alongside signal filtering. Consider the thermal performance and package size constraints relative to other available filter solutions in the PEMI4QFN series.

Part Context

This part belongs to the PEMI4QFN family of passive filter networks from NXP. Variants within this series offer different resistance and capacitance combinations to suit various impedance matching and cutoff frequency requirements. The WE variant specifically denotes the 200 Ohm/8.5 pF configuration among other options like LE or LR.

Replacement Considerations

Potential substitutes include PEMI4QFN/LE,132 and PEMI4QFN/LR,132. These alternatives share the same package and channel count but differ in resistance and capacitance values. Verify electrical compatibility before substitution.
