NFW31SP507X1E4L

Overview

The Murata NFW31SP507X1E4L is a surface-mount EMI network filter designed for signal line protection. It utilizes a third-order Pi filter topology to suppress electromagnetic interference. The component features a cutoff frequency of 500 MHz and supports a maximum voltage rating of 25 V. It handles a current capacity of 200 mA and provides an attenuation value of 6 dB at the cutoff frequency. The device is manufactured using SMD technology, ensuring compatibility with automated assembly processes.

Feature Summary

• Third-order Pi filter topology for effective noise suppression
• Surface-mount design for compact circuit integration
• Optimized performance at 500 MHz cutoff frequency

Applications

• Signal line filtering in electronic devices
• EMI suppression in low-voltage circuits
• Protection of sensitive components from high-frequency noise

Procurement Notes

Verify the specific datasheet version for the NFW31SP507X1E4L before procurement, as some sources indicate this part may be obsolete. Confirm that the 25 V rating and 200 mA current capacity align with your system requirements. Ensure the manufacturer's official documentation is referenced for accurate electrical characteristics and handling instructions.

Selection Notes

Select this component when a third-order Pi filter is required for signals up to 500 MHz. It is suitable for applications needing 25 V isolation and 200 mA current handling. Consider its surface-mount package for PCB space constraints. Verify availability status due to potential obsolescence indicators in public listings.

Part Context

This component belongs to Murata Electronics' EMI/RFI filter portfolio, specifically within the LC and RC networks category. It is engineered for signal integrity enhancement by attenuating unwanted high-frequency noise. The Pi filter structure distinguishes it from simpler LC or RC configurations, offering higher order attenuation.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Due to indications of obsolescence, alternative components should be sourced directly from Murata or authorized distributors based on updated product lifecycle data.
