Fixed Inductors Procurement Notes

Verify the complete part number including suffixes to ensure correct tolerance and packaging specifications. Confirm that the required operating temperature range aligns with the specified -40°C to 125°C limit. Check for RoHS3 compliance requirements if applicable to your assembly process. Ensure PCB land pattern matches the 0805 dimensions to prevent soldering defects during surface mount assembly.

Fixed Inductors Selection Notes

Select this component when a 390 nH inductance value is required with a 290 mA current rating. Consider the unshielded design if magnetic interference with nearby components is not a primary concern or if specific radiation patterns are needed. Evaluate the 1.5 Ohm DC resistance against power loss constraints in the target circuit. Verify that the 235 MHz self-resonant frequency exceeds the intended operating frequency for proper inductive behavior.

Fixed Inductors Part Context

This part belongs to the 0805CS series of fixed inductors from Delta Electronics/Components. The series utilizes ceramic core materials and offers various inductance values within the 0805 package form factor. These components are generally intended for general-purpose electronic applications requiring reliable surface-mount inductance solutions with standardized footprints.

Fixed Inductors Replacement Considerations

Direct substitutes must match the 390 nH inductance, 0805 package, and similar electrical parameters. Cross-reference with other manufacturers offering unshielded drum core inductors in the same footprint. Ensure any replacement maintains comparable Q factor and self-resonant frequency characteristics for circuit stability.
