NFE31PT220R1E9L

Overview

The NFE31PT220R1E9L is a surface-mount LC (T-Type) EMI filter manufactured by Murata Electronics. It features a third-order low-pass configuration with one channel and a capacitance of 22pF. The component supports a maximum current of 6A and operates at a rated voltage of 25V DC. It utilizes a 1206 (3216 Metric) package with dimensions of 3.2mm length, 1.6mm width, and 1.75mm height. The device functions within a temperature range of -40°C to 85°C and employs pad terminations for board mounting.

Feature Summary

Third-order low-pass filtering architecture utilizing LC T-type technology
High current handling capability up to 6A for power line applications
Compact 1206 surface-mount footprint with three-pad termination design

Applications

General-purpose EMI suppression in electronic circuits
Signal filtering on power lines requiring high current capacity
Electromagnetic interference reduction in consumer electronics

Procurement Notes

Verify the specific suffix codes against official Murata documentation to ensure correct capacitance and tolerance values. Confirm that the 1206 package dimensions align with your PCB layout constraints. Check RoHS compliance status and moisture sensitivity levels prior to assembly planning. Ensure the selected distributor provides valid traceability documents matching the manufacturer part number.

Selection Notes

Select this component when a third-order low-pass response is required for noise attenuation on single-channel lines. The 6A current rating makes it suitable for power supply filtering rather than signal-only paths. Consider the 22pF capacitance value for its impact on circuit impedance and cutoff frequency characteristics relative to the load.

Part Context

This component belongs to the EMIFIL NFE31 series, which focuses on combined LC type filters for EMI suppression. The series offers various capacitance options within standard surface-mount packages. The NFE31PT variant specifically denotes the T-type topology designed for efficient noise filtering in compact electronic designs.
