Fixed Inductors Procurement Notes

Verify the specific suffix 'Y' corresponds to the required tape-and-reel packaging configuration as defined in the official datasheet. Confirm that the AEC-Q200 qualification status aligns with your automotive quality management system requirements. Ensure the operating temperature range of -40°C to +125°C meets the thermal constraints of the target application environment before finalizing procurement specifications.

Fixed Inductors Selection Notes

Select this component when designing automotive power stages requiring compact shielding and high current density. The 68 µH value suits intermediate switching frequencies where moderate inductance is needed to limit ripple current. Consider the 0.39 Ω DCR for efficiency calculations in low-voltage, high-current paths. The 8028 package dimensions allow for dense PCB layouts while maintaining adequate thermal dissipation characteristics for continuous operation.

Fixed Inductors Part Context

This part belongs to the SRU8028A series of shielded SMD power inductors manufactured by Bourns Inc. The series is engineered specifically for demanding automotive environments, offering robust performance under vibration and thermal stress. The SRU8028A line provides various inductance values within the same footprint, facilitating design flexibility across different power rail requirements while maintaining consistent mechanical and electrical characteristics.

Fixed Inductors Replacement Considerations

Direct substitutes include other parts from the SRU8028A series with identical 68 µH ratings, such as variants differing only in packaging or tolerance if specified. Cross-reference with other automotive-grade shielded inductors in the 8x8 mm footprint class, ensuring matching current ratings and DCR values to maintain circuit performance without redesign.
