Procurement Notes

Verify the specific suffix 'A' in the part number to confirm automotive qualification status. Ensure the ordering quantity matches the required packaging format, such as tape and reel or cut tape. Confirm that the lead time aligns with production schedules, as standard delivery periods may vary. Cross-reference the manufacturer datasheet for any recent process change notices affecting assembly or material composition.

Selection Notes

Select this component when high current density and low profile are required in space-constrained designs. The dual-coil structure enables efficient interleaving or coupled operation in multi-phase converters. Evaluate the thermal performance based on the specified DC resistance and ambient operating conditions. Ensure the selected configuration (series or parallel) meets the target inductance and current ratings for the specific application topology.
