PEMI4QFN/WM,132

Overview

The PEMI4QFN/WM,132 is a fourth-order low-pass RC (Pi) EMI filter manufactured by NXP USA Inc. It features four independent channels housed in an 8-XFDFN surface-mount package. The component provides a resistance of 200 Ohms per channel and a total capacitance of 16 pF. Designed for signal line protection, it integrates ESD protection capabilities to safeguard sensitive electronics against electromagnetic interference and electrostatic discharge events.

Feature Summary

• Fourth-order low-pass filtering architecture for enhanced noise attenuation
• Integrated ESD protection for signal line safety
• Compact 8-XFDFN surface-mount packaging

Applications

• High-speed data bus protection
• USB interface filtering
• HDMI signal line conditioning
• General-purpose EMI suppression in consumer electronics

Procurement Notes

Verify the specific suffix 'WM' to confirm the 200 Ohm resistance and 16 pF capacitance values. Ensure the '132' tape-and-reel quantity matches your assembly requirements. Confirm the XFDFN-8 package footprint compatibility with your PCB design before ordering.

Selection Notes

Select this component when fourth-order attenuation is required for high-speed digital lines. Compare the 200 Ohm impedance against other variants like the PEMI4QFN/RR,132 which offers 100 Ohms. Ensure the total 16 pF capacitance aligns with the signal integrity requirements of the target application without causing excessive signal degradation.

Part Context

This part belongs to the PEMI4QFN family of passive filter networks from NXP. Variants within this series differ primarily in resistance and capacitance values, such as the PEMI4QFN/RT,132 or PEMI4QFN/LK,132. The WM suffix specifically denotes the 200 Ohm/16 pF configuration within this standardized product line.

Replacement Considerations

Direct substitutes include other PEMI4QFN variants with identical electrical characteristics. Verify pinout compatibility if considering cross-manufacturer alternatives.
