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, as variations may exist within the series. Check RoHS compliance status if restricted substances are a constraint for your assembly process. Ensure storage conditions align with moisture sensitivity level requirements before reflow soldering.

Fixed Inductors Selection Notes

Select this component when a low-inductance value near 20 nH is required in a minimal 0402 footprint. Consider the 420 mA current rating and 250 mOhm DCR for power loss calculations in the target circuit. The unshielded nature requires adequate spacing from sensitive components to prevent crosstalk. Verify that the 3.5 GHz self-resonant frequency exceeds the operational frequency of the application to maintain inductive behavior.

Fixed Inductors Part Context

This part belongs to the Delta Electronics 0402HS series, which specializes in high-speed, low-inductance chip inductors. The series utilizes a unique drum core structure to achieve superior high-frequency characteristics compared to standard multilayer types. These components are engineered for modern electronics demanding miniaturization and performance in RF and high-speed digital domains.

Fixed Inductors Replacement Considerations

Cross-reference with other 0402HS series variants or equivalent unshielded drum core inductors from other manufacturers. Ensure substitute parts match the 20 nH inductance, 420 mA current rating, and 0402 package dimensions. Verify that the replacement maintains similar self-resonant frequency and Q-factor specifications for critical RF applications.
