Fixed Inductors Procurement Notes

Verify the specific suffix 'EDTS' against the official Delta Electronics datasheet to confirm packaging type and tape/reel specifications. Ensure compatibility with standard SMT assembly processes for 0402 components. Check RoHS3 compliance status if required by local regulations. Confirm moisture sensitivity level (MSL 1) handling requirements during storage and reflow soldering.

Fixed Inductors Selection Notes

Select this component when a low-inductance value near 4.7 nH is required for high-frequency circuits. The unshielded design may require careful layout consideration to minimize electromagnetic interference coupling. Verify that the 800 mA current rating meets the application's peak and RMS current demands. Consider the 51 mΩ DCR impact on voltage drop and power dissipation in series configurations.

Fixed Inductors Part Context

This part belongs to the 0402HC series of fixed inductors from Delta Electronics/Components. The series offers various inductance values in a standardized 0402 package. The HC designation typically indicates high-current or high-performance characteristics within the manufacturer's portfolio. Similar parts in the series include variants with different inductance values but identical physical dimensions and mounting styles.

Fixed Inductors Replacement Considerations

Direct substitutes must match the 4.7 nH inductance, 0402 package, and similar electrical parameters. Cross-reference with other manufacturers offering 0402 unshielded drum core inductors. Verify pinout and polarity if applicable, though this is a passive component. Ensure thermal and current ratings are equivalent or superior.
