Overview
The Delevan 108R-223FS is a surface-mount RF inductor designed for high-frequency applications. It features a nominal inductance of 22 µH with a tight tolerance of ±1%. The component exhibits a maximum DC resistance of 7.5 Ω and operates within a temperature range of -55°C to +125°C. Its self-resonant frequency is specified at 19 MHz, with testing conducted at 2.5 MHz.
Feature Summary
- High precision inductance stability suitable for sensitive RF circuits
- Wide operational temperature range ensuring reliability in extreme environments
- Surface mount construction for automated PCB assembly integration
Applications
- RF choke circuits in communication systems
- Filtering components in high-frequency signal processing
- Impedance matching networks in RF transceivers
Procurement Notes
Verify the specific manufacturer source when ordering, as API Delevan assets have transitioned. Confirm RoHS compliance status directly with the supplier, as documentation indicates no explicit RoHS information is currently available for this part number. Ensure the procurement channel provides valid traceability for quality assurance purposes.
Selection Notes
Select this component for applications requiring precise 22 µH inductance with minimal deviation. The low DC resistance relative to inductance value supports efficient operation in current-limited RF paths. Consider the 19 MHz self-resonant limit when designing circuits operating near or above this frequency threshold.
Part Context
This part belongs to the fixed inductor category within Delevan's passive component portfolio. It serves as a specialized RF choke rather than a general-purpose power inductor. The design focuses on maintaining stable electrical characteristics under varying thermal conditions typical of electronic equipment.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative suppliers by matching inductance, tolerance, and physical footprint specifications before substitution.
