Fixed Inductors Procurement Notes

Verify the manufacturer part number against official Sumida documentation to ensure authenticity. Confirm that the specific suffix matches the required electrical parameters, particularly the 680 µH inductance and 310 mA current rating. Check RoHS compliance status as indicated in the datasheet. Ensure the ordering quantity aligns with standard packaging configurations provided by authorized distributors.

Fixed Inductors Selection Notes

Select this component when a compact shielded inductor is required for power applications. The 680 µH value suits moderate energy storage needs. Verify that the 160 mA saturation current meets the peak current demands of the circuit. The 1.866 Ohm DCR impacts efficiency; ensure this loss is acceptable for the design. The wide operating temperature range supports diverse environmental conditions.

Fixed Inductors Part Context

This part belongs to the CDRR series of shielded power inductors manufactured by Sumida America Components Inc. The series is designed for surface-mount technology (SMD) applications. It shares physical footprint characteristics with other variants in the CDRR family, allowing for potential design flexibility regarding inductance values while maintaining consistent board space requirements.

Fixed Inductors Replacement Considerations

Direct substitutes must match the 680 µH inductance, 6.90mm x 6.90mm footprint, and shielding type. Verify equivalent saturation and RMS current ratings. Cross-reference with Sumida's official replacement guide or distributor cross-reference tools for confirmed compatible parts.
