Fixed Inductors Procurement Notes

Verify the specific suffix against the manufacturer's latest datasheet to confirm electrical parameters and availability. Ensure the selected variant matches the required current ratings and physical footprint for the target PCB layout. Cross-reference part numbers with official Bourns documentation to avoid substitution errors.

Fixed Inductors Selection Notes

Select this component when a compact 6x6 mm footprint is required with moderate current handling capabilities up to 0.4 A. The semi-shielded design is suitable for applications needing reduced electromagnetic interference compared to unshielded types. Verify that the 2.46 Ω DCR meets the efficiency requirements of the power supply design.
