NFE31ZT222Z1E9L

Overview

The NFE31ZT222Z1E9L is a third-order LC (Pi) EMI filter manufactured by Murata Electronics. It features a capacitance of 2200 pF, a DC voltage rating of 25 V, and a current rating of 6 A. The component utilizes a T-type circuit configuration with integrated ferrite beads for low-pass filtering. Its physical dimensions are 3.2 mm in length, 1.6 mm in width, and 1.6 mm in height, housed in a 1206 (3216 Metric) package. The device meets AEC-Q200 qualification standards.

Feature Summary

• Third-order LC Pi topology for enhanced high-frequency noise attenuation
• Integrated T-type circuit design combining capacitors and ferrite beads
• AEC-Q200 qualified for automotive reliability requirements

Applications

• Low-pass filtering in general-purpose electronic circuits
• EMI suppression in automotive embedded systems
• Noise reduction in microcontroller power lines

Procurement Notes

Verify the specific suffix Z1E9L against official Murata documentation to confirm packaging and tolerance specifications. Confirm AEC-Q200 compliance status directly from the manufacturer datasheet before integration into qualified designs. Ensure the 6 A current rating aligns with system operational limits.

Selection Notes

Select this component when a compact, third-order filter solution is required for space-constrained applications. The 1206 footprint offers a balance between performance and board area. Verify that the 25 VDC rating and 6 A current handling capacity meet the specific circuit requirements for both steady-state and transient conditions.
