PEMI4QFN/RE,132

Overview

The PEMI4QFN/RE,132 is a fourth-order RC Pi-network EMI filter manufactured by NXP USA Inc. It integrates four independent channels within an 8-XFDFN surface-mount package. Each channel provides a resistance of 100 Ohms and a total capacitance of 8.5 pF. The device operates as a low-pass filter with an attenuation value of 13 dB at frequencies between 800 MHz and 3 GHz. It is designed for high-density applications requiring effective suppression of electromagnetic interference in compact electronic systems.

Feature Summary

• Integrates four independent low-pass filter channels in a single compact package
• Provides effective EMI suppression through integrated RC Pi-network topology
• Designed for surface-mount assembly to support high-density PCB layouts

Applications

• High-speed digital signal line filtering
• Power supply noise suppression in compact electronics
• EMI mitigation in mobile communication devices

Procurement Notes

Verify the exact part number suffix against official NXP documentation to ensure correct resistance and capacitance values. Confirm package type and pinout compatibility with your design. Check RoHS compliance status if required by your manufacturing standards. Ensure storage conditions meet manufacturer specifications to maintain component integrity before assembly.

Selection Notes

Select this component when multiple filtered channels are needed in a limited board area. The 100-ohm resistance and 8.5-pF capacitance values suit specific impedance matching requirements. Consider the 8-XFDFN package dimensions for thermal and spatial constraints. Evaluate the 13 dB attenuation performance against target frequency ranges to ensure adequate noise reduction.

Part Context

This component belongs to NXP's family of passive EMI/RFI filters. These devices are engineered to replace discrete resistor and capacitor networks, reducing component count and assembly time. The integration of multiple filter stages into a single package enhances reliability and simplifies layout routing for high-frequency circuits.

Replacement Considerations

Check for direct substitutes with identical 100-ohm resistance and 8.5-pF capacitance per channel. Verify that alternative packages maintain similar footprint dimensions for board compatibility. Ensure equivalent attenuation characteristics across the 800 MHz to 3 GHz range.
