Fixed Inductors Procurement Notes

Verify the specific ordering suffix matches the required packaging format, such as tape and reel or cut tape, as these affect handling procedures. Confirm that the requested quantity aligns with standard manufacturer packaging standards to avoid partial reel fees. Ensure the procurement channel is authorized to guarantee component authenticity and traceability throughout the supply chain.

Fixed Inductors Selection Notes

Select this component when a balance between low profile and moderate current handling is required. The 2.2 µH value suits applications needing efficient energy storage without excessive size. Consider the 1.8 A saturation limit to ensure stable operation during peak loads. The semi-shielded type is appropriate where some magnetic field containment is needed but full shielding is not mandatory.

Fixed Inductors Part Context

This part belongs to the NR Series V type power inductors, designed for general-purpose electronic equipment. It complements other variants in the series by offering specific inductance and current ratings within a standardized footprint. The series emphasizes miniaturization and thermal stability for modern portable and industrial devices.

Fixed Inductors Replacement Considerations

Direct substitutes include NRV3012T1R0M and NRV3012T4R7MV from the same manufacturer series. Verify that alternative parts meet identical dimensional constraints and electrical specifications. Cross-reference saturation currents and DC resistance values to ensure circuit compatibility without redesigning passive components.

Fixed Inductors FAQ

What is the difference between rated current and saturation current?

Rated current satisfies both saturation and temperature rise limits, while saturation current indicates the point where inductance drops significantly due to core magnetization.

Is the NRV3012T2R2M fully shielded?

No, it is classified as semi-shielded, which provides partial magnetic field containment while allowing for lower profile designs compared to fully shielded types.
