Procurement Notes

Verify the obsolete status of this part number before procurement planning. Confirm availability through authorized distributors or secondary markets. Ensure that any substitute components meet the original electrical specifications, including inductance, current rating, and physical dimensions, to maintain circuit integrity.

Selection Notes

Select this component for designs requiring a 33 µH unshielded inductor in a small form factor. Consider the low current handling capability of 45 mA when designing power stages. Verify thermal performance within the specified operating temperature range. Check for direct replacements if supply chain continuity is required due to discontinuation.

Part Context

This component belongs to the Delevan fixed inductor family, specifically designed for radio frequency applications. It utilizes standard surface-mount technology for PCB assembly. The unshielded variant offers distinct electromagnetic characteristics compared to shielded counterparts, suitable for specific layout constraints.

Replacement Considerations

Direct substitutes are not explicitly confirmed in public documentation. Similar alternatives may include TDK NLV25T-330J-EF, though verification of pin compatibility and electrical parameters is essential.
