] Acceleration and force are not the same thing. In this case, acceleration
] is force *per unit mass*. If you can keep the mass down on any given 
] component, then the force isn't too great, even under high acceleration.
] 

F=ma, right? So if the mass is the same, then an acceleration 350 times
that experienced on earth is due to a force 350 times that on earth, right?
Or does the mass somehow change around Jupiter? :-)

] Just design the system so that each component can support at least 350 times
] its own (Earth) weight[1]. Of course you need a safety factor and allowance
] for buffeting, so you might want to design the probe to withstand 500 G or
] more. This is still far below the requirements of the electronics in artillery 
] shells.
] 
] [1] - Bearing in mind the expected direction of the force, and the influence
] that the components have on one another.

They're doing some pretty impressive stuff with durable electronics these days.
