Overview
The Delevan 105R-221K is a micro chip inductor from the 105R series, designed for surface-mount applications. It features an unshielded wirewound construction with a ferrite core and axial termination style. The component provides an inductance of 220 nH with a tolerance of ±10%. It supports a maximum DC current of 675 mA and has a maximum DC resistance of 210 mOhms. The device operates within a temperature range of -55°C to +125°C.
Feature Summary
- Micro chip inductor design suitable for compact PCB layouts
- Unshielded wirewound construction with ferrite core
- Axial termination style for standard mounting
Applications
- General power circuit filtering
- RF signal processing stages
- DC-DC converter choke applications
Procurement Notes
Verify the specific manufacturer designation, as sources indicate API Delevan production. Confirm RoHS compliance status through official documentation before integration. Ensure the axial termination style matches the target PCB footprint requirements. Validate that the 675 mA current rating meets the operational load conditions of the final application.
Selection Notes
Select this component when a low-profile, unshielded inductor is required for space-constrained designs. The 220 nH value suits high-frequency filtering needs. Consider the 210 mOhm resistance for efficiency calculations. The wide operating temperature range supports harsh environment deployments where thermal stability is critical for consistent inductance performance.
Part Context
This part belongs to the 105R series of micro chip inductors manufactured by API Delevan. The series focuses on providing reliable passive components for modern electronic assemblies. The 105R-221K specifically addresses the need for small form factor inductors with defined electrical characteristics for power and RF circuits.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source data. Cross-referencing requires matching inductance, current rating, and physical dimensions with alternative manufacturers.
