Fixed Inductors Procurement Notes

Verify the specific suffix 'Y' against official manufacturer documentation to confirm tape and reel packaging specifications. Ensure the part number matches the required inductance tolerance and current ratings for the target application. Cross-reference the datasheet revision date to confirm compliance with current environmental standards and RoHS directives before finalizing procurement orders.

Fixed Inductors Selection Notes

Select this component when space constraints require a low-profile shielded inductor with high current handling capabilities. The 1.2 µH value suits applications requiring moderate energy storage with fast transient response. Evaluate thermal management requirements as the 16.8 mOhm DCR generates heat under full load conditions. Confirm that the 3.4 A saturation current meets peak demand without significant inductance drop.

Fixed Inductors Part Context

This part belongs to the SRU5028 family of shielded SMD power inductors designed for high-current applications. The series offers various inductance values optimized for modern power delivery networks. Bourns utilizes proprietary materials to achieve high efficiency and reliability in compact form factors suitable for dense electronic assemblies.

Fixed Inductors Replacement Considerations

Consult official Bourns substitution guides for compatible alternatives. Verify that any substitute maintains equivalent saturation current, DC resistance, and physical dimensions to ensure mechanical fit and electrical performance parity in existing designs.
