Fixed Inductors Procurement Notes

Verify the specific manufacturer part number against official Delta Electronics documentation to ensure compatibility with circuit requirements. Confirm that the RoHS3 status and MSL level 1 classification meet project standards. Cross-reference datasheet parameters such as DCR and rated current with system specifications before finalizing procurement orders.

Fixed Inductors Selection Notes

Select this component when ultra-low inductance values are required for RF applications. The 0402 size offers space efficiency, while the unshielded construction minimizes magnetic coupling issues. Ensure the operating environment stays within the specified -40°C to 125°C range and that the 1.04 A current rating aligns with peak load conditions.

Fixed Inductors Part Context

This inductor belongs to the 0402HS series from Delta Electronics/Components, which specializes in small-form-factor fixed inductors.
