Procurement Notes
Verify the specific suffix variant (e.g., KS) against project requirements, as packaging and minor specifications may differ from the base model number. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer prior to ordering. Ensure the selected package matches the PCB footprint constraints.
Selection Notes
Select this component for applications requiring a 390 nH inductance in a small SMD form factor. Consider the 635 mA current rating and 240 mΩ DCR when designing power-sensitive RF stages. Verify that the unshielded nature does not cause interference in dense layouts compared to shielded alternatives.
Part Context
This part belongs to the 103R series of Micro i Chip Inductors manufactured by API Delevan. The series is designed for high-frequency applications where small size and consistent performance are critical. The 103R designation indicates a specific footprint and construction style within Delevan's passive component portfolio.
Replacement Considerations
Cross-reference with other 103R series variants such as 103R-820KS for different inductance values. Check for direct substitutes from other manufacturers offering identical 1010 footprint dimensions and 390 nH specifications with comparable current ratings.
FAQ
