105-272J

Overview

The Delevan 105-272J is a fixed surface-mount RF inductor with a nominal inductance of 2.7 µH and a tolerance of ±5%. It features a maximum DC resistance of 2 Ω and a rated current of 220 mA. The component utilizes an iron core within an epoxy encapsulated construction, housed in a nonstandard two-lead SMT package.

Feature Summary

• Designed for radio frequency applications as a general-purpose inductor
• Epoxy encapsulated construction for environmental protection
• Iron core material provides specific magnetic characteristics

Applications

• RF circuit filtering
• General purpose signal processing
• Surface mount assembly

Procurement Notes

Verify component status carefully as the 105-272J is listed as obsolete by major distributors. Confirm availability through secondary market channels or authorized stockists. Ensure datasheet revisions match design requirements before finalizing procurement plans to avoid integration issues.

Selection Notes

Select this component only if legacy compatibility is required due to its obsolete status. Evaluate alternative surface-mount inductors with similar 2.7 µH values and 220 mA ratings from active manufacturers. Consider physical footprint constraints and thermal performance when replacing obsolete parts.

Part Context

This part belongs to the Delevan 105 series of fixed inductors. The series typically includes variants with different tolerances such as the 105-272F (1% tolerance). The 105-272J specifically denotes the 5% tolerance variant within this product line.

Replacement Considerations

No public confirmed substitute part numbers are available. The component is marked as obsolete. Designers must source equivalent specifications from other manufacturers or utilize existing inventory.
