Fixed Inductors Procurement Notes
Verify the specific suffix 'L1' against manufacturer documentation to confirm exact electrical tolerances and packaging specifications. Ensure compatibility with RoHS3 standards and check moisture sensitivity levels prior to assembly. Confirm lead-free status and ECCN classification for export compliance requirements.
Fixed Inductors Selection Notes
Select this component when space-constrained designs require high saturation currents near 28 A. The low DCR minimizes power loss in high-amperage paths. Evaluate the 11.2 mm footprint against board layout constraints. Consider the 320 nH value for switching frequencies around 100 kHz.
Fixed Inductors Part Context
This part belongs to the HCB1190 series of high-current SMT power inductors. The series offers inductance values ranging from 0.22 µH to 0.55 µH.
