NFL15ST157X0J3D

Overview

The NFL15ST157X0J3D is a third-order low-pass LC filter manufactured by Murata Electronics. It features a T-type topology designed for EMI/RFI suppression in compact electronic systems. The component integrates an inductance of 115nH and a capacitance of 22pF within a single package. It supports a maximum current rating of 50 mA and operates at a voltage of 6.3 volts. The device is housed in a standard 0402 (1005 Metric) surface-mount footprint, facilitating automated assembly and high-density circuit board layouts.

Feature Summary

• Integrates LC filtering elements into a monolithic structure to minimize circuit board space requirements.
• Provides third-order attenuation characteristics for effective high-frequency noise suppression.
• Utilizes a T-type configuration to maintain signal integrity while blocking electromagnetic interference.

Applications

• Portable mobile communication devices requiring compact EMI protection
• Wireless local area network modules needing RF interference filtering
• Compact consumer electronics with limited PCB real estate

Procurement Notes

Verify the complete part number including suffixes against official Murata documentation to ensure correct termination and tolerance specifications. Confirm that the 50 mA current rating aligns with the target application's operational limits. Check for RoHS compliance status in the latest datasheet revision before finalizing procurement orders.

Selection Notes

Select this component when space constraints preclude discrete LC components. Ensure the operating voltage does not exceed 6.3V to prevent dielectric breakdown. Validate that the 115nH inductance provides sufficient impedance for the specific noise frequencies present in the design environment.

Part Context

This component belongs to Murata's NFM series of feed-through capacitors and integrated filters. These parts are engineered for high-performance noise suppression in portable electronics. The series emphasizes miniaturization without compromising filtering efficiency or power handling capabilities.

Replacement Considerations

Consult official Murata substitution guides for verified equivalents. Cross-reference electrical parameters such as inductance, capacitance, and current ratings to ensure functional compatibility.
