108-823KS

Overview

The Delevan 108-823KS is a fixed surface-mount RF inductor with an inductance of 82 µH and a tolerance of 10%. It features a maximum DC resistance of 28 Ohms and a rated current of 30 mA. The component utilizes an iron core and measures 2.54 mm in length, 2.54 mm in width, and 1.91 mm in height. It is designed for PCB mounting and operates within a temperature range of -55°C to +125°C.

Feature Summary

• Unshielded SMD construction suitable for RF applications
• Iron-core design providing stable inductance characteristics
• Standard two-terminal surface mount termination

Applications

• RF circuit filtering
• Signal processing networks
• General purpose RF impedance matching

Procurement Notes

This component is officially discontinued by the manufacturer. Availability is restricted to existing stock or secondary market suppliers. Verify end-of-life notifications and ensure alternative sourcing strategies are in place for production continuity. Check RoHS compliance details carefully as legacy components may not meet current environmental standards.

Selection Notes

Select this part only if its specific 82 µH value and 30 mA current rating align with the target circuit requirements. Consider the high DC resistance of 28 Ohms when evaluating power loss. Due to discontinuation, evaluate equivalent replacements from other manufacturers that match the physical footprint and electrical specifications.

Part Context

The 108 series represents Delevan's line of unshielded surface-mount inductors. These components are characterized by their small form factor and iron-core construction, targeting compact RF designs where shielding is not strictly required. This specific model belongs to the legacy portfolio now marked as obsolete.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Evaluate generic equivalents based on matching 82 µH inductance, 2.54 x 2.54 mm footprint, and 28 Ohm DCR constraints.
