Fixed Inductors Procurement Notes

Verify the specific suffix designation against the manufacturer's official datasheet to confirm electrical tolerances and material specifications. Ensure that the selected variant meets the required RoHS compliance status for the target assembly process. Cross-reference the DigiKey part number DN7687-ND for accurate ordering details and availability status.

Fixed Inductors Selection Notes

Select this component when a low-inductance, high-current solution is required for axial mounting. Compare the 0.47 µH value against circuit requirements to ensure proper impedance characteristics. Consider the 1.3 A current rating for power handling needs and verify the 85 MHz self-resonant frequency aligns with the operating bandwidth.

Fixed Inductors Part Context

This part belongs to the Delevan 1025(R) series of fixed inductors. The series offers various inductance values tailored for RF and general electronic applications. Components in this family share common physical dimensions and mounting styles while differing in electrical parameters such as inductance, current rating, and core materials.

Fixed Inductors Replacement Considerations

Direct substitutes include other Delevan 1025R variants with matching 0.47 µH inductance and similar current ratings. Verify cross-compatibility with MIL-PRF-M15305 standards if military-grade reliability is required. Check equivalent offerings from other manufacturers only if pinout and electrical specs match exactly.
