PEMI8QFN/CP,132

Overview

The PEMI8QFN/CP,132 is an RC (Pi) EMI filter manufactured by NXP USA Inc. It functions as a second-order low-pass filter with eight channels. The component features a resistance of 20 Ohms and a total capacitance of 18.5 pF. It provides ESD protection and achieves an attenuation value of 13 dB at frequencies between 800 MHz and 3 GHz. The device is housed in a 16-XFDFN package with an exposed pad.

Feature Summary

• Integrates RC Pi network topology for second-order low-pass filtering
• Provides electrostatic discharge (ESD) protection capabilities
• Offers multi-channel signal conditioning with eight independent paths

Applications

• EMI suppression in high-speed digital interfaces
• Signal integrity enhancement for data lines
• ESD protection circuits in consumer electronics

Procurement Notes

Verify the complete part number including the suffix ,132 to ensure correct reel packaging configuration. Confirm RoHS compliance status matches project requirements. Cross-reference the XFDFN package dimensions against PCB footprint specifications to prevent assembly errors. Ensure the supplier provides official NXP documentation for quality assurance.

Selection Notes

Select this component when eight-channel filtering is required within a compact surface-mount form factor. The 20 Ohm resistance and 18.5 pF capacitance values define the cutoff characteristics suitable for specific frequency ranges. Consider the exposed pad thermal design for proper heat dissipation during operation.

Part Context

This component belongs to the PEMI8 family of integrated EMI filters from NXP Semiconductors. These devices are designed to replace discrete LC or RC networks, reducing board space and assembly complexity. The QFN variant offers a low-profile solution for dense PCB layouts requiring robust noise suppression.

Replacement Considerations

Check for direct substitutes within the PEMI8 series that may offer different channel counts or electrical parameters. Verify pin compatibility and package dimensions before substituting with other manufacturers' RC filter arrays.
