Procurement Notes

Verify current availability status as the component may be subject to discontinuation or limited supply constraints. Confirm RoHS compliance requirements, as this specific part number indicates non-compliance. Ensure that the standard terminal configuration and bulk packaging format align with your assembly process capabilities before finalizing procurement decisions.

Selection Notes

Select this component when a precise 330 nH inductance is required for RF circuits with moderate current handling needs up to 500 mA. Consider its unshielded nature regarding potential electromagnetic interference coupling in dense layouts. Evaluate the 400 mOhm DC resistance impact on power loss relative to alternative shielded options if space permits larger form factors.

Part Context

This part belongs to the Delevan 106 series of fixed SMD RF inductors. These components utilize iron core materials and are designed for high-frequency applications requiring stable inductance values. The series offers various inductance options within a standardized footprint, facilitating design flexibility for RF engineers working with legacy or specific impedance requirements.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the discontinued status indicated by official notifications, direct pin-compatible replacements from other manufacturers should be evaluated based on electrical equivalence rather than guaranteed cross-reference lists.
