Hi,
Why are the recomended pads on this TDK inductor so small?......they should be big as possible under the body...for heat dissipation.....its a shielded inductor so copper under the part wont get eddy current heated.

In use in SMPS, the pads should be big as poss?

Hi,

I´d say the package drawings show a small pad. Just for soldering and for low parasitic capacitance.

The designer is free to choose a bigger copper area for heat spreading and and carrying current.
