PEMI4QFN/RR,132

Overview

The PEMI4QFN/RR,132 is a surface-mount EMI filter circuit manufactured by NXP USA Inc. It features an RC (Pi) topology configured as a second-order low-pass filter with four independent channels. The component integrates passive filtering elements with specific electrical characteristics: each channel includes a resistance of 100 Ohms and a total capacitance of 21 pF. Designed for compact applications, it utilizes an 8-XFDFN package to provide efficient signal integrity management in space-constrained electronic designs.

Feature Summary

• Integrates a four-channel RC Pi-filter network for multi-line signal conditioning
• Provides second-order low-pass filtering characteristics to attenuate high-frequency noise
• Combines passive filtering with electrostatic discharge protection capabilities

Applications

• High-speed data line protection in portable consumer electronics
• EMI suppression for USB or similar interface ports
• Signal integrity enhancement in compact mobile devices

Procurement Notes

Verify the exact part number suffix against official NXP documentation to ensure correct configuration. Confirm that the 8-XFDFN package dimensions match your PCB footprint requirements. Check for RoHS compliance status and moisture sensitivity level specifications prior to procurement to ensure compatibility with your assembly process and storage conditions.

Selection Notes

Select this component when a multi-channel solution is required for simultaneous noise reduction on multiple lines. The integrated ESD protection feature reduces the need for separate protective components. Ensure the 100 Ohm resistance value aligns with the impedance requirements of the connected transmission lines to prevent signal reflection issues.

Part Context

This device belongs to the PEMI4QFN family of EMI filter circuits from NXP Semiconductors. The family offers various configurations tailored for different channel counts and filtering needs. The RR variant specifically denotes the RC Pi-filter topology with integrated ESD protection, distinguishing it from LC or other passive filter variants within the same product line.

Replacement Considerations

Consult the official NXP datasheet for direct pin-to-pin compatible alternatives within the PEMI4QFN series. Verify that any substitute maintains the same 100 Ohm resistance and 21 pF capacitance values to preserve circuit performance.
