Fixed Inductors Procurement Notes

Verify RoHS compliance status as sources indicate non-compliance or leaded content. Confirm package quantity and reel specifications with the manufacturer. Ensure the specific suffix matches required tolerance and current ratings. Check for alternative lead-free variants if environmental regulations require it.

Fixed Inductors Selection Notes

Select this part for applications requiring 330 µH inductance with tight ±3% tolerance. Consider the 14 Ω DC resistance and 190 mA current limit for power handling. The unshielded design requires layout consideration for magnetic interference. Verify operating temperature requirements against the -55 °C to 125 °C range.

Fixed Inductors Part Context

Part of the Delevan 4470 series, which includes various inductance values and tolerances. The series offers both shielded and unshielded options with different core materials. This specific model uses an iron core and molded epoxy encapsulation for durability.

Fixed Inductors Replacement Considerations

Check for equivalent 330 µH axial inductors with similar current ratings. Verify physical footprint compatibility for through-hole mounting. Ensure DC resistance and Q-factor meet circuit requirements.
