NFE31PT101C1E9L

Overview

The Murata NFE31PT101C1E9L is a surface-mount LC (T-type) EMI filter designed for signal line suppression. It features a third-order low-pass configuration with a capacitance of 100 pF and supports a maximum current of 6 A at 25 V DC. The component utilizes a three-pad 1206 (3216 Metric) footprint, measuring 3.2 mm in length, 1.6 mm in width, and 1.6 mm in height. It operates within a temperature range of -40°C to +85°C and complies with RoHS standards.

Feature Summary

• Integrates LC T-type architecture for effective high-frequency noise attenuation
• Provides robust current handling capability suitable for power-sensitive signal lines
• Utilizes a compact three-terminal surface-mount design for space-constrained layouts

Applications

• General-purpose EMI suppression in electronic circuits
• Signal line filtering in portable devices
• Noise reduction in automotive electronics

Procurement Notes

Verify the complete part number including suffixes to ensure correct capacitance and termination specifications. Confirm package dimensions and thermal ratings against target application requirements. Check official manufacturer documentation for latest compliance status and recommended soldering profiles to ensure reliable assembly.

Selection Notes

Select this component when a third-order low-pass response is required for signal integrity. Ensure the 6 A current rating exceeds the operational load. Verify that the 1206 footprint aligns with the PCB layout constraints. Consider the 100 pF capacitance value for appropriate cutoff frequency characteristics relative to the signal bandwidth.

Part Context

This component belongs to the Murata EMIFIL NFE31P series, which specializes in chip EMI filters combining inductive and capacitive elements. The series offers various capacitance values within the same 1206 package form factor, allowing designers to tailor filtering performance without altering the physical board footprint.

Replacement Considerations

Cross-reference with other NFE31PT variants offering different capacitance values if filtering characteristics require adjustment. Verify equivalent LC T-type structures from other manufacturers only if pinout and electrical parameters match exactly.
