NFE61PT181B1H9L

Overview

The NFE61PT181B1H9L is a third-order low-pass LC(T-type) EMI filter capacitor manufactured by Murata Electronics. It features a capacitance of 180 pF and supports a maximum current of 2 A with a rated DC voltage of 50 V. The component utilizes a surface-mount package with dimensions of 6.8 mm in length, 1.6 mm in width, and 1.9 mm in height, corresponding to the 2706 (6816 metric) footprint. It operates within a temperature range of -40°C to +85°C and includes three terminal pads for mounting.

Feature Summary

• Integrates feedthrough capacitor and ferrite bead functions in a single compact SMD package
• Provides high attenuation performance through third-order low-pass filtering architecture
• Supports high current handling capability suitable for power line applications

Applications

• General purpose EMI suppression in electronic circuits
• Signal filtering on power supply lines
• RFI reduction in automotive or industrial control systems

Procurement Notes

Verify the specific suffix codes against the official Murata datasheet to ensure correct capacitance tolerance and termination specifications. Confirm that the 2706 package dimensions align with your PCB layout constraints. Check RoHS compliance status and moisture sensitivity level requirements before finalizing procurement orders.

Selection Notes

Select this component when space-constrained designs require combined filtering and decoupling capabilities. The 2 A current rating makes it suitable for powering sensitive loads while suppressing noise. Ensure the operating voltage does not exceed 50 V DC and verify thermal management meets the -40°C to +85°C operational range.

Part Context

This part belongs to the Murata EMIFIL NFE61P series, which combines LC filter technology with feedthrough capacitor structures. The series is designed for efficient EMI/RFI suppression in small form factors. The NFE61PT variant specifically denotes surface-mount packaging with specific termination characteristics defined by the manufacturer's coding system.

Replacement Considerations

Consult Murata's official cross-reference documentation for verified substitutes. Direct replacements must match the 180 pF capacitance, 2 A current rating, and 2706 package dimensions. Verify equivalent third-order filtering performance and temperature ratings before substitution.
