0819-22H

Overview

The Delevan 0819-22H is an axial leaded RF inductor with a nominal inductance of 0.82 µH and a tolerance of ±3%. It features a molded unshielded construction with a maximum DC resistance of 220 mΩ and a rated current of 465 mA. The component exhibits a minimum Q factor of 40 and a self-resonant frequency of 200 MHz, suitable for high-frequency circuit applications.

Feature Summary

• Molded unshielded coil design
• Axial lead termination style
• High-Q performance at RF frequencies

Applications

• RF circuits
• PCB mount assemblies

Procurement Notes

Verify the manufacturer designation, as API Delevan assets are managed by different entities. Confirm RoHS compliance status through official documentation. Ensure the specific suffix 'H' corresponds to the required 3% tolerance and 465 mA rating. Cross-reference datasheets for any recent product change notifications affecting electrical parameters or physical dimensions.

Selection Notes

Select this component for applications requiring axial mounting in RF environments. The unshielded design necessitates careful layout to minimize interference. Verify that the 465 mA current rating meets the circuit's operational requirements. Consider the 200 MHz self-resonant frequency limit when designing for higher frequency bands.

Part Context

This part belongs to the 0819 series of fixed RF inductors manufactured by Delevan. The series offers various inductance values with different tolerance options indicated by suffixes. The 0819-22H specifically provides a balance of moderate inductance and current handling in an axial package format.

Replacement Considerations

The 0819-22F serves as a direct substitute with identical electrical characteristics but a tighter 1% tolerance. Other 0819 series variants may be considered if inductance values differ.
