NFA18SL407V1A45L

Overview

The NFA18SL407V1A45L is an LC EMI filter manufactured by Murata Electronics, designed for surface mount applications. It features a second-order low-pass configuration with four channels and a rated current of 100 mA. The component utilizes a 0603 (1608 Metric) array package with dimensions of 1.60mm x 0.80mm x 0.65mm. It has a cutoff frequency of 400MHz and provides 25dB attenuation at 800MHz. The device operates within a temperature range of -40°C to 85°C and carries a rated voltage of 10V.

Feature Summary

• Integrates four independent low-pass filter channels in a compact surface-mount array
• Provides effective electromagnetic interference suppression using LC technology
• Designed for high-density PCB layouts with standardized footprint dimensions

Applications

• General purpose signal line filtering
• Data bus protection in electronic circuits
• EMI suppression in mobile devices

Procurement Notes

Verify the specific part number against official Murata documentation to confirm current lifecycle status, as availability may vary. Ensure that the selected variant matches the required electrical specifications, including cutoff frequency and current rating, for the intended application. Cross-reference package dimensions and pin configurations with target PCB footprints prior to procurement.

Selection Notes

Select this component when a multi-channel low-pass filter is required for EMI reduction in space-constrained designs. The 0603 array package supports dense mounting, while the 100mA rating suits moderate current applications. Consider the 400MHz cutoff frequency relative to the signal bandwidth to ensure adequate attenuation without affecting desired frequencies.

Part Context

This component belongs to the Murata EMIFIL NFA18 series, which offers various LC filter configurations for different frequency ranges and current requirements. The series is characterized by its small form factor and reliability in consumer electronics. The NFA18SL407V1A45L specifically targets applications requiring 400MHz cutoff performance in a standard 0603 footprint.

Replacement Considerations

Check Murata's official substitution list for compatible alternatives with similar cutoff frequencies and channel counts. Verify that any substitute maintains the same package dimensions and electrical ratings to ensure mechanical and functional compatibility.
