NFL18ST157X1C3D

Overview

The NFL18ST157X1C3D is a surface-mount EMI filter circuit manufactured by Murata Electronics. It utilizes an LC (T-type) topology to provide low-pass filtering for high-speed signal lines. The component operates within a voltage rating of 16 V and supports a current rating of 100 mA. Key electrical parameters include an inductance of 140 nH, capacitance of 32 pF, and a cutoff frequency of 150 MHz. It is housed in a 0603 (1608 metric) package with three PCB pads, measuring 1.60 mm in length, 0.80 mm in width, and 0.90 mm in height.

Feature Summary

• Delivers sharp roll-off characteristics for effective noise suppression on high-speed signal lines.
• Achieves T-type structure integration within a compact 1.6x0.8mm footprint using multilayer technology.

Applications

• Noise suppression for high-speed digital signal lines
• EMI filtering in mobile communication devices
• Signal integrity protection in consumer electronics

Procurement Notes

Verify the specific part number against official Murata documentation to confirm technical specifications and availability status. Check for any product discontinuation notices or lifecycle changes prior to procurement. Ensure compatibility with surface-mount assembly processes and verify that the 0603 package dimensions align with the target design constraints.

Selection Notes

Select this component when a compact solution is required for filtering high-speed signals with a cutoff frequency around 150 MHz. The 16 V rating and 100 mA current capacity suit standard logic-level applications. Consider the 0603 package size for space-constrained designs requiring T-type LC filtering performance without increasing board area.

Part Context

This component belongs to the NFL18ST series from Murata Electronics, designed specifically for EMI suppression in small form factors. The series employs multilayer technology to integrate inductive and capacitive elements into a single surface-mount device. This approach allows for efficient noise filtering while maintaining minimal profile and footprint suitable for modern dense PCB layouts.

Replacement Considerations

Consult official Murata documentation for verified substitute part numbers. Cross-referencing requires matching electrical parameters such as cutoff frequency, inductance, capacitance, and package dimensions to ensure functional equivalence in the application.
