• Axial leaded termination for through-hole mounting
• Fixed inductance value with tight tolerance stability

Applications

• RF circuit filtering
• Signal processing networks
• Energy storage in radio frequency systems

Procurement Notes

Verify RoHS compliance status as documentation indicates non-compliance. Confirm package type availability, as sources list both bulk and reel options. Ensure ordering quantities align with manufacturer standard packaging requirements. Cross-reference datasheet revisions to confirm electrical parameter consistency before procurement.

Selection Notes

Select this component for applications requiring 22 µH inductance in unshielded configurations. Consider the 105 mA current limit and 4.3 Ohm DC resistance when designing power stages. Compare against the 0819R-56K variant if RoHS compliance is mandatory, noting potential differences in manufacturing specifications or environmental certifications.

Part Context

Part of the API Delevan 0819 series of molded unshielded RF coils. This series offers various inductance values with consistent physical dimensions (5.08 mm x 1.98 mm). The 0819-56K specifically targets mid-range inductance needs in RF designs where shielding is not required.

Replacement Considerations

The 0819R-56K is a direct substitute within the same series, offering identical electrical characteristics but potentially different environmental compliance status.
