Fixed Inductors Procurement Notes

Verify the specific ordering suffix 'Y' corresponds to the tape and reel packaging configuration required for your production line. Confirm that the 2.2 µH inductance value and 2.5 A current ratings align precisely with the design specifications of the target application circuit before finalizing procurement orders.

Fixed Inductors Selection Notes

Select this component when a compact shielded inductor is required for space-constrained designs. Ensure the operating environment remains within the -55°C to 125°C temperature range. Verify that the 2.05 A saturation current limit meets the peak current demands of the specific power stage to prevent performance degradation.

Fixed Inductors Part Context

This part belongs to the Bourns SRR4028 series of shielded SMD power inductors. The series utilizes a drum core design with silver/nickel/tin terminations. The 'SRR4028' designation indicates the physical footprint and form factor, while the numeric suffix specifies the electrical characteristics.

Fixed Inductors Replacement Considerations

Cross-reference other SRR4028 series variants for different inductance values or current ratings. Verify compatibility with existing PCB footprints if substituting with similar shielded inductors from alternative manufacturers.
