Fixed Inductors Procurement Notes

Verify the specific part number suffix against official manufacturer documentation to confirm exact electrical tolerances and packaging configurations. Ensure that the selected variant matches the required saturation current and DC resistance specifications for the target application circuit. Cross-reference the datasheet for moisture sensitivity level and reflow soldering profile requirements to guarantee reliable integration into the final electronic assembly.

Fixed Inductors Selection Notes

Select this component when a compact surface-mount solution with millihenry-level inductance is required for low-current buck converters. The 12x12mm footprint offers a balance between size and thermal dissipation. Consider the 1.718 Ohm DC resistance impact on efficiency and the 0.61 A saturation limit to prevent core saturation under peak load conditions during transient events.
