PEMI4QFN/LE,132

Overview

The PEMI4QFN/LE,132 is a second-order low-pass RC (Pi) EMI filter manufactured by NXP USA Inc. It features four independent channels within an 8-XFDFN surface-mount package. Each channel integrates a resistor with a resistance of 65 Ohms and a total capacitance of 8.5 pF distributed across the network. This component is designed for effective suppression of electromagnetic interference in high-density electronic circuits.

Feature Summary

• Integrates a Pi-network RC topology for second-order low-pass filtering characteristics
• Provides four distinct signal channels within a compact surface-mount footprint
• Utilizes an XFDFN package design suitable for automated assembly processes

Applications

• High-speed data line protection in consumer electronics
• EMI suppression for USB or similar interface ports
• Signal integrity enhancement in dense PCB layouts

Procurement Notes

Verify current availability status as this specific part number is scheduled for obsolescence and will be discontinued by the manufacturer. Confirm that the 65 Ohm resistance and 8.5 pF capacitance values align with your circuit requirements before finalizing procurement decisions due to limited future supply.

Selection Notes

Select this component when a multi-channel, low-profile EMI solution is required for differential or single-ended lines. The fixed 65 Ohm resistance and 8.5 pF capacitance define the cutoff frequency; ensure these values match the impedance and filtering needs of the target application without requiring external discrete components.

Part Context

This device belongs to the PEMI4 series of integrated EMI filters from NXP. It serves as a specialized passive component for noise reduction, differing from general-purpose capacitors by combining resistive and capacitive elements in a single monolithic structure optimized for high-frequency attenuation.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the scheduled obsolescence, engineers should evaluate alternative multi-channel RC filters with compatible pinouts and electrical specifications from other manufacturers.
