Fixed Inductors Procurement Notes

Verify the manufacturer part number against official Ole Wolff Electronics documentation to ensure authenticity. Confirm that the received components match the specified 22 µH inductance and 1616 package dimensions. Check for RoHS compliance status as indicated in supplier listings. Ensure storage conditions preserve the integrity of the molded resin shield.

Fixed Inductors Selection Notes

Select this component when low acoustic noise and high mechanical durability are required in space-constrained designs. The semi-shielded architecture offers a balance between cost and electromagnetic performance. Consider the 590 mA current limit and 468 mOhm resistance for power efficiency requirements in the target circuit topology.

Fixed Inductors Part Context

This part belongs to the OWINR4018 series from Ole Wolff Electronics, which specializes in acoustic and magnetic solutions. The series includes variants such as OWINR4018-2R2 and OWINR4018-680, sharing the same physical footprint and construction technology but differing in inductance values and current ratings.

Fixed Inductors Replacement Considerations

Direct substitutes within the same series include OWINR4018-2R2 and OWINR4018-680, though these differ in electrical specifications. Cross-brand replacements require matching the 1616 package, 22 µH inductance, and current handling capabilities while verifying shielding characteristics.
