Hello I have a unique need for an h-bridge driver (basically use it as a controlled DPDT). I need a part that will handle +/- 5A, and in addition it will be used in an MRI environment.. so the material from which it is made matters. Nickel and tin are particularly bad. I would need something constructed and plated with copper, copper alloy, gold, silver (or with similar magnetic susceptibilities).. .. can anyone direct me toward a part? how to find the material compositions?
Cheers
Dean
