Fixed Inductors Procurement Notes

Verify RoHS compliance status as this component may contain lead. Confirm datasheet version matches specific manufacturing lot requirements. Check for established reliability variants if higher performance standards are required. Ensure axial lead dimensions fit target PCB layout constraints prior to ordering.

Fixed Inductors Selection Notes

Select based on 1.2 µH inductance requirement and 730 mA current rating. Consider the 420 mΩ DCR impact on power loss. Verify 180 MHz self-resonant frequency suitability for target operating band. Compare against shielded alternatives if EMI mitigation is necessary.

Fixed Inductors Part Context

Part of the Delevan 1537 series of fixed RF inductors. Shares physical dimensions (9.53 mm length, 3.96 mm diameter) with other series members like 1537R-14J. Offers similar form factor but differs in electrical parameters and shielding characteristics compared to shielded variants.

Fixed Inductors Replacement Considerations

1537-14J serves as a direct functional substitute within the same series offering identical 1.2 µH inductance and physical dimensions.
