It features an unshielded wirewound construction with a ferrite core, housed in a non-standard package size. The component provides an inductance of 22 µH with a tight tolerance of 2%. It supports a maximum DC current of 57 mA and exhibits a maximum DC resistance of 7.5 Ohms. Key electrical characteristics include a minimum Q factor of 32 and a self-resonant frequency of 2.5 MHz, ensuring stable performance in high-frequency circuits.
Feature Summary
- Unshielded wirewound design suitable for specific RF layout requirements
- High precision 2% inductance tolerance for accurate circuit tuning
- Ferrite core material optimized for radio frequency signal integrity
Applications
- RF choke circuits
- Radio frequency filtering networks
- Impedance matching stages
Procurement Notes
Verify the exact physical dimensions against the official datasheet before integration, as this component utilizes a non-standard package footprint rather than common industry sizes. Confirm that the 57 mA current rating aligns with the target application's peak load requirements to prevent saturation or thermal issues during operation.
Selection Notes
Select this part when precise 22 µH inductance is required in space-constrained designs where shielding is not mandatory. The low current handling capability necessitates careful evaluation of the operating environment. Consider alternative shielded variants if electromagnetic interference suppression is critical for the system.
Part Context
This component belongs to the Delevan series of fixed surface-mount inductors. It is specifically engineered for radio frequency applications requiring stable inductance values. The unshielded configuration distinguishes it from shielded counterparts, offering different magnetic field propagation characteristics for specialized RF circuit topologies.
Replacement Considerations
The S1210R-223G serves as a shielded alternative within the same manufacturer lineup, though it differs in package dimensions and shielding properties. Direct substitution requires verification of board space and magnetic isolation requirements.
