Fixed Inductors Procurement Notes

Verify the specific suffix code against the manufacturer's official datasheet to confirm exact electrical tolerances and packaging configuration. Ensure the ordering part number matches the required inductance value and current rating for the target application circuit. Confirm compliance requirements such as RoHS3 status directly with the supplier documentation prior to purchase.

Fixed Inductors Selection Notes

Select this component when a compact 1616 footprint is required for power filtering applications. Consider the 840 mA current rating and 234 mOhm resistance for efficiency calculations. Evaluate the semi-shielded design benefits for noise-sensitive environments where reduced electromagnetic interference is critical compared to unshielded alternatives.

Fixed Inductors Part Context

This model belongs to the OWINR4018 series of fixed inductors manufactured by Ole Wolff Electronics Inc. The series offers various inductance values including 10 µH, 47 µH, and 68 µH variants. All members share the same 1616 package dimensions and similar shielding technologies, providing consistent mechanical profiles for board layout standardization across different power management designs.

Fixed Inductors Replacement Considerations

Direct substitutes include other 10 µH inductors in the 1616 package with comparable current ratings. Verify that replacement components meet or exceed the 840 mA rating and 234 mOhm DCR specifications. Ensure the alternative part maintains RoHS3 compliance and compatible operating temperature ranges for seamless integration.
