High-current power inductor

Shielded high-current SMD power inductors in the Würth Elektronik WE-HCI sizes: the body and the two terminal tabs underneath. The inductor is centred on the origin, sitting on the XY plane, with the tabs at the -Y and +Y ends, centred on X. Inductance doesn't change the outside of a size.
