Fixed Inductors Procurement Notes

Verify the specific manufacturer designation, as API Delevan assets may be managed by other entities. Confirm RoHS compliance status and REACH SVHC details through official documentation. Ensure the ordering suffix matches the required packaging quantity and reel specifications for automated assembly processes.

Fixed Inductors Selection Notes

Select this component when high current capacity is required in a compact surface-mount footprint. The low DC resistance minimizes power loss in high-current paths. Verify that the 220 nH value aligns with the target circuit's frequency response and ripple requirements compared to alternative inductance values in the same series.

Fixed Inductors Part Context

This part belongs to the 4922R series of high-power surface-mount inductors manufactured by Delevan. The series offers various inductance values optimized for different current ratings while maintaining consistent physical dimensions. These components are designed for robust performance in demanding power electronics environments.

Fixed Inductors Replacement Considerations

Direct substitutes within the same series include 4922R-221L or 4922R-221KS if specific tolerance or shielding variations are acceptable. Cross-reference electrical parameters such as saturation current and DCR to ensure functional equivalence in the target application.
