Fixed Inductors Procurement Notes

Verify the manufacturer part number against official Delta Electronics documentation to ensure authenticity. Confirm that the specific suffix matches the required electrical parameters, particularly the 3.9 nH value and 1.7 A rating. Check RoHS compliance status and moisture sensitivity level requirements before procurement. Ensure storage conditions align with the specified operating temperature range to maintain component integrity.

Fixed Inductors Selection Notes

Select this component when a very low inductance value near 4 nH is required for high-frequency applications. The 0402 footprint suits space-constrained designs. Consider the 1.7 A current rating for power delivery paths. Verify that the unshielded design does not interfere with nearby sensitive components due to potential magnetic field emission.

Fixed Inductors Part Context

This part belongs to the 0402HP series of fixed inductors from Delta Electronics/Components. The series offers various inductance values within the 0402 package size. This specific model targets applications requiring minimal inductance with high current capacity and high self-resonant frequencies typical of RF and high-speed digital circuits.

Fixed Inductors Replacement Considerations

Cross-reference other 0402HP series variants or similar 0402 fixed inductors from Delta if exact stock is unavailable. Ensure replacement parts match the 3.9 nH inductance, 45 mOhm DCR, and 1.7 A current rating. Verify package dimensions and terminal compatibility for direct substitution.
