Re: Trouble with some devices


 

The thing I don't see specified on the schematic, is the proximity between the wire
and the ground plane. The amount of inductance depends not on its length but on the
loop area enclosed by the wire and its return path (ground plane), so you would get
totally different results for a PCB trace as opposed to a wire suspended above the
circuit board.
Yes, the standard "it's not what is on the schematic that you should be concerned about, it's what is not on the schematic" problem.
