On many arcade boards, I see some aggressive ESD protection (?) around all the connectors. It's often a lot of 3-pin parts, each sitting between a connector pin and an IC pin. A good example is the side-facing board on a NAOMI, with the IO connections. There's a ton of these unlabeled 3-pin parts, in the way of every signal.
These seem to be some kind of filter network, I guess to absorb transients from the switches/cables/whatever. Does anyone know the actual values for these parts? Does anyone know where to source them?
I'm designing some boards that ought to have similar protection, but this is a bit outside my expertise.
