# 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.

The model uses the middle of each range. The tabs also run up the end faces on the real part; the model has the bottom tabs only.

**Proportions, for looks only:** the tabs' 0.1 mm thickness under the body.
