Fixed Inductors Procurement Notes

Verify the specific manufacturer part number against official API Delevan documentation to confirm electrical parameters and physical dimensions. Ensure compatibility with your PCB footprint and thermal management requirements. Check for RoHS compliance status if required by your manufacturing standards. Confirm lead times directly with authorized distributors as availability may vary.

Fixed Inductors Selection Notes

Select this component when shielded inductance is critical to prevent crosstalk in dense layouts. The 680 nH value suits high-frequency switching applications. Verify that the 1.32 A current rating meets the peak load requirements of your circuit. Consider the 119 mOhm DCR impact on overall efficiency and heat dissipation in the final design.

Fixed Inductors Part Context

This part belongs to the SP1210R series of shielded surface-mount power inductors manufactured by API Delevan. The series is characterized by its drum core geometry, which combines high current handling with reduced electromagnetic interference compared to unshielded alternatives. These components are widely used in modern electronics where space constraints and signal integrity are primary design drivers.

Fixed Inductors Replacement Considerations

Consult official API Delevan substitution guides or distributor cross-reference tools for verified equivalents. Ensure any substitute matches the 680 nH inductance, 1.32 A current rating, and 1210 package dimensions. Verify that the replacement maintains the shielded drum core architecture to preserve EMI performance.
