NFM31KC153R1H3L

Overview

The Murata NFM31KC153R1H3L is a three-terminal feedthrough capacitor designed for high-frequency noise suppression. It features a capacitance of 0.015 µF with a ±20% tolerance and a rated DC voltage of 50V. The component supports a maximum current of 10 A and exhibits a low DC resistance of 1.5 mΩ. Housed in a 1206 (3216 Metric) surface-mount package, it operates within a temperature range of -55°C to +125°C. This device is qualified under the AEC-Q200 standard, ensuring reliability for automotive applications.

Feature Summary

• Three-terminal feedthrough architecture provides superior high-frequency noise attenuation compared to conventional two-terminal capacitors.
• Low internal inductance design enables effective suppression of electromagnetic interference on high-speed signal and power lines.
• AEC-Q200 qualification ensures robust performance and reliability suitable for demanding automotive electronic environments.

Applications

• Power line filtering in automotive electronic control units
• Noise suppression for high-speed digital circuits
• EMI reduction in automotive infotainment systems

Procurement Notes

Verify the complete part number including suffixes to ensure correct capacitance, voltage rating, and termination specifications. Confirm AEC-Q200 qualification status if automotive application requirements are mandatory. Check RoHS compliance documentation for environmental regulations. Ensure storage conditions align with moisture sensitivity level classifications to prevent soldering defects during assembly.

Selection Notes

Select this component when high-current handling capability and low impedance are critical for noise suppression. The 1206 footprint offers a balance between size and performance. Consider the 10 A current rating to ensure adequate margin for the specific circuit load. Evaluate the 50 VDC rating against peak voltage transients in the target application environment.

Part Context

This component belongs to the Murata EMIFIL NFM31 series of three-terminal filter capacitors. The series is engineered for compact designs requiring efficient EMI/RFI suppression. The NFM31KC variant specifically targets applications needing high current capacity and stable performance across wide temperature ranges.

Replacement Considerations

Direct substitutes must match the 1206 package, 0.015 µF capacitance, 50 V rating, and three-terminal feedthrough structure. Verify that alternative parts meet the same AEC-Q200 qualification and 10 A current handling capabilities to maintain circuit integrity.
