0819-16K

Overview

The Delevan 0819-16K is a fixed axial leaded RF inductor from the 0819 series. It features a molded unshielded coil construction with an inductance of 470 nH and a tolerance of ±4%. The component has a maximum DC current rating of 410 mA and a maximum DC resistance of 620 mOhms. It exhibits a minimum Q factor of 25 and a self-resonant frequency of 340 MHz. Physical dimensions include a length of 5.08 mm and a diameter of 1.98 mm, designed for PCB mount applications.

Feature Summary

• Molded unshielded coil design for compact integration
• Axial leaded termination style for through-hole mounting
• High self-resonant frequency capability for RF circuits

Applications

• RF circuit filtering
• Impedance matching networks
• General purpose RF signal processing

Procurement Notes

Verify RoHS compliance status as documentation indicates non-compliance. Confirm that the specific suffix 'K' corresponds to the 4% tolerance variant rather than standard options. Ensure procurement channels support the required reel packaging quantity if applicable. Validate physical footprint compatibility before finalizing supply chain agreements.

Selection Notes

Select this component when a 470 nH inductance value with tight 4% tolerance is required for RF applications. Consider the 410 mA current limit and 620 mOhm resistance for power handling constraints. The unshielded design necessitates careful layout planning to prevent magnetic coupling with adjacent components in dense PCB assemblies.

Part Context

This part belongs to the Delevan 0819 series of fixed RF inductors. The series offers various inductance values and tolerance codes, with the 'K' suffix specifically denoting the 4% tolerance level. These components are engineered for reliability in radio frequency environments requiring stable inductive performance.

Replacement Considerations

The 0819-16G serves as a direct substitute within the same series, offering identical electrical parameters but with a 2% tolerance specification instead of 4%. Both parts share the same physical dimensions and mounting style.
