0819-22G

Overview

The Delevan 0819-22G is a leaded RF inductor from the 0819 series, designed for printed circuit board mounting. It features an axial termination style and an unshielded molded coil construction. The component has an inductance of 820 nH with a tolerance of 2%. It supports a maximum DC current of 465 mA and exhibits a maximum DC resistance of 220 mOhms. The minimum Q factor is 25, with a self-resonant frequency of 340 MHz. Physical dimensions include a length of 5.08 mm and a diameter of 1.98 mm.

Feature Summary

• Molded unshielded coil construction for RF applications
• Axial leaded termination style suitable for PCB mounting
• High self-resonant frequency capability

Applications

• RF circuits
• Radio frequency signal processing
• Electronic filter networks

Procurement Notes

Verify the specific manufacturer designation, as sources list both API Delevan Inc. and generic Delevan. Confirm RoHS compliance status through official documentation, as some listings indicate non-compliance while others show detailed information. Ensure the ordering suffix matches the required tolerance and packaging configuration for production integration.

Selection Notes

Select this component when an 820 nH inductance value is required with tight 2% tolerance. The 465 mA current rating and low DCR make it suitable for moderate current RF paths. Consider the unshielded design for applications where magnetic interference isolation is not critical or where space constraints favor the compact axial form factor.

Part Context

This part belongs to the Delevan 0819 series of fixed RF inductors. The series offers various inductance values with different tolerance codes indicated by the final letter. The 0819-22G specifically provides a balance of high-frequency performance and moderate current handling within a standard axial package format common in legacy and specialized RF designs.

Replacement Considerations

Cross-reference with other 820 nH axial RF inductors if availability is constrained. Verify that substitute components match the 220 mOhm DCR and 465 mA current limits to maintain circuit performance.
