NFA21SL506X1A48L

Overview

The Murata NFA21SL506X1A48L is a surface-mount LC EMI filter array designed for high-density applications. It features four channels within a compact 0805 (2012 metric) package, measuring 2 mm in length, 1.25 mm in depth, and 0.85 mm in height. The component operates with a maximum DC voltage of 10V and a current rating of 20 mA. It provides a cutoff frequency of 50 MHz and includes an integrated capacitance value of 80 pF per channel. The device supports soldering termination and functions reliably across a temperature range from -55°C to +125°C.

Feature Summary

• Integrates four independent low-pass LC filter channels into a single compact footprint
• Provides effective electromagnetic interference suppression at frequencies up to 50 MHz
• Designed for automotive electronics requiring robust performance under varying thermal conditions

Applications

• Automotive electronics signal line protection
• High-density multi-channel data interface filtering
• Compact consumer electronic circuit boards

Procurement Notes

Verify the specific suffix X1A48L against official Murata documentation to confirm exact electrical tolerances and packaging configuration. Ensure compatibility with automated pick-and-place equipment due to the small 0805 form factor. Confirm RoHS compliance status through the manufacturer's latest certification records before integration into regulated assemblies.

Selection Notes

Select this component when space constraints require multiple filtered lines within a standard 0805 area. It is suitable for low-voltage digital signals where minimal insertion loss and high current handling relative to size are required. Consider the 20 mA limit for power integrity planning in sensitive automotive or industrial control circuits.

Part Context

This part belongs to the NFA21SL series of EMIFIL arrays manufactured by Murata Electronics. These components are engineered specifically for automotive and industrial environments, offering reliable EMI/RFI noise reduction. The series utilizes combined LC technology to achieve superior filtering characteristics compared to simple capacitor networks.

Replacement Considerations

Consult official Murata substitution guides for direct equivalents. Verify pinout compatibility and electrical parameters such as cutoff frequency and current ratings before replacing with alternative LC filter arrays.
