PEMI8QFN/HM,132

Overview

The PEMI8QFN/HM,132 is an eight-channel RC Pi-type EMI/RFI filter manufactured by NXP USA Inc. It features a resistance of 45 Ohms per channel and a total capacitance of 16 pF. The component provides attenuation of 15 dB at frequencies between 800 MHz and 3 GHz. It is housed in a 16-XFDFN package with an exposed pad, designed for surface-mount assembly to suppress electromagnetic interference in high-speed digital interfaces.

Feature Summary

• Eight-channel configuration for simultaneous signal line filtering
• RC Pi-network topology for effective EMI suppression
• Compact surface-mount design suitable for dense PCB layouts

Applications

• High-speed data interface protection
• Consumer electronics signal integrity enhancement
• Industrial control system noise reduction

Procurement Notes

Verify the exact suffix HM against the manufacturer's current datasheet to confirm pinout and electrical specifications. Ensure the XFDFN package dimensions match your PCB footprint requirements. Confirm RoHS compliance status if required for your specific regulatory environment. Cross-reference the part number with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when eight independent filtered lines are required within a single compact package. The 45 Ohm resistance value is suitable for standard logic levels without significant signal degradation. Consider the 16 pF total capacitance impact on signal rise times for your specific application speed. Evaluate thermal dissipation needs based on the exposed pad design.

Part Context

This component belongs to the family of passive EMI filters offered by NXP Semiconductors. It addresses the growing need for noise suppression in modern electronic devices where multiple high-speed signals coexist in close proximity. The integration of multiple channels into one package reduces board space compared to discrete filter solutions.

Replacement Considerations

Check Nexperia datasheets for equivalent RC filter networks with similar 45 Ohm resistance and low capacitance values. Verify that any substitute maintains the same 16-XFDFN package outline and pin assignment to ensure mechanical compatibility.
