Overview
The Delevan 108-823JS is an unshielded surface-mount RF inductor with an inductance of 82 µH and a tolerance of ±5%. It features a maximum DC resistance of 28 Ohms and a rated current of 30 mA. The component utilizes nonstandard two-terminal SMD/SMT termination for PCB mounting. Its physical dimensions are defined by the 108R series form factor, designed for compact radio frequency circuit integration.
Feature Summary
- Unshielded chip construction for radio frequency applications
- Surface mount technology with standard two-terminal configuration
- Ferrite core design providing stable inductance characteristics
Applications
- Radio frequency signal processing circuits
- RF impedance matching networks
- High-frequency filtering stages
Procurement Notes
Verify end-of-life status before procurement as this component is listed as obsolete or discontinued by the manufacturer. Confirm availability through authorized distributors or secondary market suppliers. Ensure compatibility with existing PCB footprints and validate electrical parameters against original design specifications to prevent performance degradation in critical RF systems.
Selection Notes
Select this component for designs requiring high inductance values in small RF modules. Consider the low current rating of 30 mA when designing power stages. Verify that the unshielded nature does not cause interference in dense layouts. Compare against shielded alternatives if electromagnetic compatibility is a primary constraint.
Part Context
This part belongs to the Delevan 108R series of RF inductors. It is distinct from the SP1210R series which offers shielding and higher current ratings. The 108R series is characterized by its specific footprint and unshielded architecture, targeting niche radio frequency applications where size and cost are prioritized over magnetic containment.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete lifecycle status, direct pin-to-pin replacements may require redesigning the PCB layout or selecting alternative manufacturers with similar unshielded RF inductor specifications.
