Fixed Inductors Procurement Notes

Verify component authenticity and datasheet alignment when sourcing, as availability may vary across distributors. Confirm that the specific variant matches the required 68 µH inductance and 1.2 A current rating for your design. Check for RoHS compliance status if environmental regulations apply to your project. Ensure the radial lead format fits your PCB layout constraints before finalizing procurement decisions.

Fixed Inductors Selection Notes

Select this component when an unshielded radial inductor is required for space-constrained through-hole designs. The 68 µH value suits moderate frequency filtering tasks. Consider the 1.2 A current limit to ensure adequate headroom for your circuit's peak loads. The unshielded nature may require careful placement to minimize electromagnetic interference with nearby sensitive components.

Fixed Inductors Part Context

This part belongs to the API Delevan 4554 series of fixed inductors. The series offers various inductance values and current ratings in a consistent radial package. The 4554-680K specifically targets applications needing 68 µH. Similar parts in the family include variants with different inductance values like 4554-470K or 4554-6R8M, sharing the same physical form factor.

Fixed Inductors Replacement Considerations
