PEMI8QFN/RR,132

Overview

The PEMI8QFN/RR,132 is an EMI/RFI filter manufactured by NXP USA Inc. It functions as a second-order low-pass RC (Pi) filter with eight channels. The component features a resistance of 100 Ohms and a total capacitance of 21pF. It is housed in a 16-XFDFN package with an exposed pad.

Feature Summary

• Provides electromagnetic interference suppression through second-order low-pass filtering characteristics
• Integrates eight independent filtering channels within a single compact package
• Utilizes an RC Pi network topology for signal integrity enhancement

Applications

• High-speed digital interface noise reduction
• Signal line filtering in embedded systems
• EMI mitigation in portable electronic devices

Procurement Notes

Verify the specific suffix RR against official NXP documentation to confirm the exact resistance and capacitance values. Ensure the XFDFN package dimensions match the target PCB footprint. Confirm availability status directly with the manufacturer or authorized distributors, as component lifecycle stages may affect long-term supply.

Selection Notes

Select this component when eight-channel EMI filtering is required for high-speed signals. The 100 Ohm resistance and 21pF capacitance define the cutoff frequency characteristics. Compare the XFDFN package size against available board space. Verify that the voltage ratings meet the system requirements for the protected lines.

Part Context

This part belongs to the PEMI series of integrated EMI filters from NXP. These components are designed to replace discrete LC or RC networks, saving board space and assembly time. The series offers various resistance and capacitance combinations to suit different impedance matching and filtering needs.

Replacement Considerations

Check for direct substitutes with identical 100 Ohm/21pF specifications and the same 16-XFDFN package. Verify pinout compatibility before substitution. Other suffixes in the PEMI8QFN family may offer different electrical parameters.
