Fixed Inductors Procurement Notes

Verify the specific manufacturer part number against official API Delevan documentation to confirm electrical parameters and physical dimensions. Ensure compatibility with existing PCB footprints and thermal requirements. Confirm RoHS compliance status if required by project specifications. Cross-reference datasheets for accurate handling and storage guidelines.

Fixed Inductors Selection Notes

Select this component when a high-inductance value of 180 µH is required in a shielded axial package. Consider the 190 mA current rating and 4 Ohm DC resistance for power loss calculations. Evaluate the operating temperature range against environmental conditions. Compare performance metrics with unshielded alternatives if EMI mitigation is not critical.

Fixed Inductors Part Context

This component belongs to the Delevan 1537 series of fixed RF inductors. The series offers various inductance values in a consistent axial form factor. These components are designed for reliable performance in radio frequency applications requiring stable inductance and noise reduction through shielding.

Fixed Inductors Replacement Considerations

Direct substitutes include other 180 µH shielded axial RF inductors from API Delevan, such as the 1537-736J (220 µH) or similar series members. Verify that replacement parts match the 190 mA current rating and 4 Ohm resistance limits.
