Fixed Inductors Procurement Notes

Verify the manufacturer part number 0402HP-300EJTS against official Delta Electronics documentation to ensure authenticity. Confirm RoHS3 compliance and MSL level 1 status during incoming inspection. Check for any specific handling requirements related to the ceramic core construction. Ensure storage conditions maintain component integrity prior to assembly.

Fixed Inductors Selection Notes

Select this component when a 30 nH inductance value is required in a minimal 0402 footprint. Consider the 450 mA current rating and 330 milliohm DCR for power efficiency needs. The unshielded design may require layout considerations for EMI sensitivity. Verify that the 3.3 GHz self-resonant frequency aligns with the target application bandwidth.

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. These components are designed for general-purpose RF and power applications requiring small form factors. The 0402HP designation indicates the specific series characteristics and performance class.

Fixed Inductors Replacement Considerations

Direct substitutes include other 30 nH, 0402, 450 mA inductors from different manufacturers if pinout and dimensions match. Verify electrical parameters such as DCR and SRF closely. Cross-reference with Delta's own series variants if minor parameter adjustments are acceptable.
