PEMI8QFN/WG,132

Overview

The PEMI8QFN/WG,132 is an EMI/RFI filter manufactured by NXP USA Inc., classified under passive components. It utilizes an RC Pi network topology to provide second-order low-pass filtering characteristics. The device integrates resistors with a value of 200 Ohms and capacitors totaling 11pF within a single surface-mount package. Designed for signal integrity protection, it operates effectively in environments requiring noise suppression across multiple channels.

Feature Summary

• Integrates RC Pi network topology for second-order low-pass filtering
• Provides multi-channel EMI and RFI noise suppression
• Features compact surface-mount packaging for space-constrained designs

Applications

• High-speed digital signal line protection
• EMI suppression in consumer electronics
• Noise filtering in communication interfaces

Procurement Notes

Verify the manufacturer designation carefully, as this component appears in listings for both NXP USA Inc. and Nexperia USA Inc. due to historical corporate relationships. Confirm the specific suffix WG matches the required pinout and electrical specifications. Ensure the source document explicitly identifies the part as an RC Pi filter with 200 Ohm resistance and 11pF capacitance before procurement.

Selection Notes

Select this component when a multi-channel solution is required for simultaneous noise attenuation on parallel data lines. The integrated RC Pi structure simplifies board layout compared to discrete components. Verify that the 200 Ohm resistance value aligns with the impedance requirements of the driven circuit to prevent signal degradation while maintaining effective high-frequency attenuation.

Part Context

This component belongs to the family of integrated passive devices designed for electromagnetic interference mitigation. Unlike active filters, it relies on passive RC elements to attenuate high-frequency noise without requiring external power. The QFN-style package allows for efficient thermal dissipation and minimal footprint usage in dense printed circuit board assemblies.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-referencing requires matching the exact RC values (200 Ohm, 11pF total) and channel count. Verify compatibility with the original design's impedance constraints before considering alternative manufacturers.
