Re: help me with coil on pcb

A rough rule of thumb is 1nH per millimeter of straight track so 6.2nH is a very small inductor paticularly if you need some bends in it.

Printed coils have high flux leakage and are affected by close metal objects such
as other components or a metal box. You may need to fabricate several iterations of the PCB design or do a full electromagnetic simulation of the PCB layout.
