NFW31SP506X1E4L01

Overview

The NFW31SP506X1E4L01 is a third-order low-pass LC (Pi) EMI filter manufactured by Murata Electronics. It features a single channel with a maximum current rating of 200 mA and operates within a voltage range up to 25 V DC. The component utilizes a surface-mount 1206 (3216 Metric) package configuration, specifically designed for three-pad mounting. This filter is engineered to suppress electromagnetic interference in compact electronic circuits.

Feature Summary

• Provides third-order low-pass filtering characteristics using an LC Pi topology
• Designed for high-density surface-mount applications in the 1206 footprint
• Capable of handling continuous currents up to 200 mA

Applications

• Electromagnetic interference suppression in portable electronics
• Signal line protection in compact consumer devices
• Power integrity management in space-constrained circuit boards

Procurement Notes

Verify the specific ordering suffix against official Murata documentation to ensure correct termination and packaging specifications. Confirm that the 200 mA current rating and 25 V voltage limits align with your system requirements before integration. Cross-reference the 1206 pad layout with your PCB design guidelines to ensure mechanical compatibility.

Selection Notes

Select this component when a third-order attenuation profile is required in a minimal 1206 footprint. Ensure the application current does not exceed 200 mA and the operating voltage remains within the 25 V DC limit. Consider the three-pad surface mount requirement during PCB layout planning to maintain signal integrity and mechanical stability.

Part Context

This part belongs to Murata's NFW series of passive EMI filters. These components are distinct from general-purpose capacitors or inductors, as they integrate multiple elements into a single package to provide complex filtering networks. The NFW series is designed for applications requiring significant noise reduction without occupying excessive board area.

Replacement Considerations

Consult official Murata substitution guides for verified equivalents. Do not assume generic LC filters are compatible due to potential differences in impedance profiles, current ratings, or parasitic characteristics.
