108-823H

Overview

The Delevan 108-823H is a fixed RF inductor designed for surface-mount applications. It features an unshielded wirewound construction with an iron core, providing an inductance of 82 uH and a tolerance of 3%. The component exhibits a maximum DC resistance of 28 Ohms and supports a maximum current of 30 mA. Its self-resonant frequency is specified at 2.5 MHz, with a Q-factor of 30. The physical dimensions are 2.54 mm in length, 2.54 mm in width, and 1.91 mm in height.

Feature Summary

• Unshielded wirewound design utilizing an iron core for RF signal processing
• Surface-mount termination suitable for automated PCB assembly processes
• High stability inductance with tight manufacturing tolerances

Applications

• RF circuit filtering and impedance matching networks
• General-purpose radio frequency signal conditioning

Procurement Notes

Verify the exact suffix designation, as official documentation references both 108R-823H and 108-823H. Confirm RoHS compliance status through the manufacturer's latest certification documents. Ensure the selected variant matches the required lead frame and termination specifications for your specific PCB footprint requirements before finalizing procurement orders.

Selection Notes

Select this component when an unshielded RF inductor is required to minimize magnetic interference coupling in adjacent circuits. The 82 uH value and 2.5 MHz self-resonant frequency define its operational bandwidth limits. Consider the 28 Ohm DC resistance impact on power loss within the target circuit topology during initial design phase evaluations.

Part Context

This part belongs to the Delevan 108R series of fixed RF inductors. The series offers various inductance values tailored for radio frequency applications. The 108-823H specifically utilizes an iron core material, distinguishing it from ferrite-core variants within the broader product family line.

Replacement Considerations

Direct substitute part numbers are not explicitly confirmed in the provided public documentation. Verify pin compatibility and electrical parameters against alternative SMD RF inductors from other manufacturers if discontinuation occurs.
