Procurement Notes

Verify RoHS compliance status as documentation indicates non-compliance or variable availability depending on production batch. Confirm package quantity requirements, typically supplied in reels of 1000 units. Ensure lead time and stock levels are checked directly with authorized distributors due to potential supply chain variability for this specific part number.

Selection Notes

Select the 0819-20G when a compact, unshielded axial inductor with 680 nH nominal value is required. Consider the 2% tolerance and 485 mA current rating against circuit demands. Compare against other series members like 0819-20H if higher current capacity or different tolerance is needed. Verify self-resonant frequency constraints for high-frequency operation.

Part Context

This component belongs to the Delevan 0819 series of fixed RF inductors. The series offers various inductance values and tolerances, all sharing similar physical dimensions and axial leaded packaging. The 0819-20G specifically targets applications requiring precise low-inductance values with tight tolerance specifications.

Replacement Considerations

Direct substitutes within the same series include 0819-20H (3% tolerance) and 0819-20F (1% tolerance). Cross-series replacements require matching inductance, current rating, and physical footprint. Verify that alternative components meet the same self-resonant frequency and Q factor requirements.
