About Cornell Dubilier, I did not leak any information for your Cornell Thin Aluminum Capacitor.
No, I did not leak any... I don't know if they can leak I have the expert 2 years ago in a chat-conference and It did not come to my mind if they are !
Because the ebay rail gun is officially online and accessible, plating it with old Cornell Ampacitor was an apparent subject ongoing actually in State.
"Cornell Dubilier THA and THAS ThinPack capacitors are designed for high capacitance bulk storage and filtering in space-critical applications, with both series available with capacitance values from 18,000µF at 10V to 140µF at 450V. This allows designers to replace entire bulk storage arrays, which can reduce PCB area by approximately 70% while also reducing size and weight. The reduced part count also simplifies assembly and improves reliability. "

And couple of arduino news as well.
