Procurement Notes

Verify the specific datasheet version to confirm exact electrical tolerances and physical dimensions before integration. Ensure that the through-hole footprint matches the target PCB layout constraints. Confirm RoHS compliance status if required by regional regulations. Check for any AEC-Q200 automotive qualification requirements, as this part is noted as non-compliant with that standard.

Selection Notes

Select this component when high current capacity and strong common mode rejection are required in space-constrained through-hole designs. The nanocrystalline construction provides superior performance compared to traditional ferrite cores at specific frequencies. Consider the 16A rating against peak load currents to ensure thermal stability. Verify that the 3.2 mH inductance aligns with the filter cutoff requirements of the circuit design.
