NFM41PC155B1E3L

Overview

The Murata NFM41PC155B1E3L is a three-terminal feedthrough capacitor designed for high-frequency noise suppression. It features a capacitance of 1.5 µF with a tolerance of -20% to +50%. The component has a rated DC voltage of 25V and supports a maximum current rating of 6 A. Its direct current resistance (DCR) is 9 mΩ maximum. The device operates within a temperature range of -55°C to +85°C. It utilizes an SMD package in the 1806 (4516 metric) footprint, measuring 4.50 mm in length, 1.60 mm in width, and 1.20 mm in height.

Feature Summary

• Three-terminal feedthrough structure provides low impedance grounding path for effective EMI suppression.
• High current handling capability allows integration into power lines without signal degradation.
• Compact surface-mount design facilitates automated assembly and dense PCB layout.

Applications

• Power supply input filtering for electronic equipment
• EMI suppression in high-speed digital circuits
• Noise reduction in automotive electronics systems

Procurement Notes

Verify the specific suffix code against official Murata documentation to confirm voltage and tolerance ratings. Ensure the ordering quantity aligns with standard reel sizes or cut-tape availability. Confirm RoHS3 compliance status if required by project specifications. Cross-reference the manufacturer part number with authorized distributor catalogs to prevent counterfeit components.

Selection Notes

Select this component when a 1.5 µF capacitance value is required at 25V DC. The 6 A current rating suits applications involving moderate power line filtering. The 1806 package size is appropriate for space-constrained designs requiring robust thermal and electrical performance. Consider the -55°C to +85°C operating range for standard industrial environments.

Part Context

This component belongs to the Murata EMIFIL NFM41PC series of feedthrough capacitors. These devices are engineered for broadband noise suppression in compact form factors. The series offers various capacitance and voltage options within the same mechanical footprint, allowing designers to maintain consistent board layouts while adjusting electrical characteristics.

Replacement Considerations

Consult official Murata substitution guides for verified equivalents. Alternative parts must match the 1806 package dimensions and 1.5 µF capacitance. Verify that substitute components support the 6 A current rating and 25V DC requirement. Ensure compatibility with existing PCB pad layouts and soldering profiles.
