Fixed Inductors Procurement Notes

Verify the specific suffix 'RY' against official manufacturer documentation to confirm physical dimensions and terminal compatibility. Confirm RoHS3 compliance status through current datasheets. Check lead times as components may be made-to-order. Ensure storage conditions align with moisture sensitivity level requirements before soldering.

Fixed Inductors Selection Notes

Select this component when circuit designs require high inductance values within compact surface-mount footprints. The shielded construction minimizes magnetic field leakage, making it suitable for densely packed boards. Verify that the 500 mA current rating meets the peak load requirements of the target application without saturation.

Fixed Inductors Part Context

This part belongs to the SCRH family of low-current SMD inductors. The series offers various inductance values in standardized open-frame or shielded constructions. The SCRH105RY variant specifically denotes shielded units with defined non-standard package dimensions, distinguishing them from standard footprint alternatives within the same electrical family.

Fixed Inductors Replacement Considerations

Consult official substitution lists for electrically equivalent parts. Cross-reference pinout and thermal characteristics if replacing with generic equivalents. Ensure any substitute maintains the 820 µH value and 1.77 ohm DCR limits.
