NFL18SP157X1A3D

Overview

The NFL18SP157X1A3D is a third-order LC Pi EMI filter circuit manufactured by Murata Electronics. It operates with a rated voltage of 10 V and a current rating of 100 mA. The component features an inductance of 100 nH and a capacitance of 34 pF, providing filtering at a frequency of 150 MHz. It utilizes a surface-mount (SMD/SMT) termination type within a 0603 (1608 metric) package measuring 1.6 mm in length, 0.8 mm in width, and 0.6 mm in height.

Feature Summary

• Third-order LC Pi topology for enhanced noise suppression
• Compact 0603 surface-mount form factor
• Designed for automotive electronics applications

Applications

• Automotive electronics power line filtering
• General purpose signal line protection

Procurement Notes

Verify the current lifecycle status before procurement as this component may be discontinued or subject to obsolescence notices. Confirm that the 10 V voltage rating and 100 mA current capacity align with the target circuit requirements. Ensure the 0603 footprint matches the PCB layout constraints. Check for valid replacement part numbers if active sourcing is required.

Selection Notes

Select this component when a third-order low-pass filter response is necessary within a constrained 0603 space. The 100 nH inductance and 34 pF capacitance values are specific to the 150 MHz design point. Verify compatibility with the 10 V operating voltage and ensure the 100 mA current handling meets the application load demands without saturation.

Part Context

This part belongs to the Murata EMIFIL NFL series of EMI filter circuits. These components are engineered for high-density electronic assemblies requiring effective electromagnetic interference reduction. The NFL series typically offers various configurations including T and Pi networks tailored for specific frequency attenuation profiles in compact packages.

Replacement Considerations

Public documentation indicates this product is no longer manufactured. Verify official substitute part numbers from Murata or equivalent manufacturers offering compatible LC Pi topologies with matching 0603 dimensions and electrical ratings.
