0819-80H

Overview

The Delevan 0819-80H is a leaded RF inductor featuring an axial termination style and unshielded molded construction. It provides an inductance of 220 uH with a tolerance of 3% and a maximum DC resistance of 26.5 ohms. The component supports a maximum DC current of 42.5 mA and achieves a minimum Q factor of 35. Its self-resonant frequency is specified at 3.3 MHz. Designed for PCB mounting, the unit measures 5.08 mm in length and 1.98 mm in diameter.

Feature Summary

• Molded unshielded coil construction for RF applications
• Axial leaded termination for standard PCB mounting
• High inductance value within the 0819 series

Applications

• RF circuit design
• Signal processing networks
• Filtering components

Procurement Notes

Verify the specific manufacturer designation when sourcing this component, as documentation may reference API Delevan or simply Delevan. Confirm that the axial leaded package and molded unshielded construction match the target design requirements. Ensure the electrical parameters, particularly the 220 uH inductance and 42.5 mA current rating, align with the intended RF application constraints before finalizing procurement.

Selection Notes

Select this component for applications requiring high inductance values in a compact axial form factor. The unshielded design necessitates careful layout consideration to prevent magnetic interference with adjacent components. Verify that the operating frequency remains below the 3.3 MHz self-resonant point to maintain inductive behavior. The 3% tolerance offers precision suitable for tuned circuits where strict parameter control is necessary.

Part Context

This part belongs to the Delevan 0819 series of RF inductors, characterized by molded unshielded coils and axial leads. The series covers a wide range of inductance values, with the 0819-80H representing a higher inductance option compared to lower-value counterparts like the 0819-10H. These components are engineered for reliability in radio frequency environments.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Cross-referencing should be performed carefully to ensure compatibility with axial leaded mounting and unshielded magnetic characteristics.
