NFM31HK103R1H3L

Overview

The NFM31HK103R1H3L is a three-terminal feed-through capacitor from Murata's EMIFIL NFM31 series, designed for high-current applications. It features a capacitance of 10 nF with a ±20% tolerance and a DC voltage rating of 50 V. The component supports a rated current of 6 A and exhibits a maximum 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 for automotive reliability.

Feature Summary

• Three-terminal structure providing low equivalent series inductance (ESL) for effective high-frequency noise suppression.
• Capable of handling high continuous currents up to 6 A, suitable for powertrain and safety equipment circuits.
• AEC-Q200 qualification ensures compliance with automotive electronic component stress test requirements.

Applications

• Automotive powertrain systems
• Vehicle safety equipment circuits
• High-current EMI filtering in automotive electronics

Procurement Notes

Verify the specific suffix 'L' corresponds to the reel packaging configuration required for your assembly line. Confirm that the 1206 footprint matches your PCB design constraints. Ensure the 50V rating and 6A current capacity align with your circuit's operational limits. Check for RoHS3 compliance status if environmental regulations apply to your manufacturing process.

Selection Notes

Select this component when designing circuits requiring simultaneous high current handling and significant capacitance in a compact form factor. The NFM31HK series is appropriate where low ESL is critical for suppressing electromagnetic interference in noisy environments. Consider the 1206 package size relative to available board space and thermal management capabilities during operation.

Part Context

This part belongs to Murata's EMIFIL NFM31 family of very large current three-terminal low ESL chip multilayer ceramic capacitors. These components are specifically engineered for demanding automotive applications, distinguishing them from standard MLCCs by their specialized internal electrode structure designed to minimize parasitic inductance while maintaining high current throughput.

Replacement Considerations

Direct substitutes include other parts within the NFM31HK series with identical or compatible electrical parameters, such as NFM31HK104R1H3L for higher capacitance. Verify pinout compatibility and physical dimensions before substituting with components from other manufacturers to ensure proper fit and function in existing designs.
