✅ Inductance: 22µH matches the required 22µH.
✅ Inductance tolerance: ±20% matches the required ±20% or tighter.
✅ Current rating: 5A exceeds the required ≥3A, providing adequate current handling margin.
✅ Saturation current: 8A exceeds the required ≥3.5A, giving strong saturation margin for buck converter operation.
✅ DC resistance: 45mΩ max is well below the required ≤120mΩ, supporting lower conduction loss and better efficiency.
✅ Type: Shielded wirewound is explicitly specified by the part details.
✅ Mounting type: Surface Mount matches the requirement.
✅ Operating temperature range: -55°C to +125°C is wider than the required -40°C to +125°C.
✅ RoHS compliance: ROHS3 Compliant satisfies the requirement.
All required specifications are satisfied. This component is approved for the stated buck converter inductor selection task.
