Inductor Requirements

I am looking for the requirements for the DCDC inductor - the datasheet is light on details. Can you provide additional details? The reference designs include 0603 but I need smaller so want to make sure the inductor I spec is appropriate.

Thanks,
John

Thanks for the reply.

Thanks for the reply.

I am running from a primary lithium cell, so running buck.

Ideally, we could go as small as possible, but 0402 would be a big space gain on 0603.

Thanks,
John

Hello,

Hello,
Was there ever any resolution on this matter? What should we look for in an inductor if we are interested in replacing the 0603 with a smaller one?
