Sorry for that  :-\

I´m triying to make my project PoE powered with the SI3402B. I looked for schematics and i got one from an evaluation board.

When designing the PCB, should i place components on the output power traces in a linear order?

Can i just create a plane and attach all the components to it?

I mean in the picture attached there´s Vpos rail that ends in 5v. There aren´t any components in series on this rail. Can i connect every component to a VPos plane?

On the negative rail there are components in series so i must place some components like D1 before L1 and so on.
