Overview
The Delevan 108-223FS is a fixed surface-mount RF inductor designed for high-frequency circuit applications. It features an unshielded construction with a nominal inductance of 22 µH and a tight tolerance of 1%. The component exhibits a maximum DC resistance of 7.5 Ohms and supports a maximum DC current of 57 mA. It utilizes a non-standard package footprint with two leads, suitable for PCB mounting. The unit weighs approximately 100 mg and operates within standard industrial temperature ranges.
Feature Summary
- Unshielded design minimizes magnetic interference coupling
- High precision 1% inductance tolerance ensures signal integrity
- Compact SMD form factor for space-constrained layouts
Applications
- RF filtering circuits
- Impedance matching networks
- Signal processing modules
Procurement Notes
Verify the specific non-standard package dimensions against target PCB footprints prior to integration. Confirm that the 57 mA current rating aligns with operational requirements. Ensure compatibility with reflow soldering profiles specified in the manufacturer datasheet. Validate RoHS compliance status if required by project specifications.
Selection Notes
Select this component when precise inductance values are critical for RF performance. The unshielded nature requires careful layout planning to prevent crosstalk. Compare against shielded alternatives if electromagnetic interference suppression is necessary. Consider the physical size constraints relative to other SMD inductor series.
Part Context
This part belongs to the Delevan fixed inductor portfolio, specifically targeting radio frequency applications. It differs from shielded variants by exposing the magnetic field, which influences board layout strategies. The 108 designation indicates a specific case size distinct from standard metric codes like 1210 or 1812.
Replacement Considerations
Direct substitutes include the 108R-223FS variant. Cross-reference with other 22 µH unshielded SMD inductors ensuring identical tolerance and current ratings.
