[TCML] DIY Tank Capacitor - Plate configuration confusion

[bartb]

Hi Jason,

That's interesting. I think in the 942C case, the construction technique 
has four major benefits:

1) division across the dielectric
2) to aid uniformity of the electric field.
3) High voltage and high capacitance in a small package.
4) End terminal construction allows high peak currents at low loss.

Also note, the 942C could have easily used a floating plate between two 
normally sized plates, but the choice to separate the foil on the same 
layer appears to be predominately voltage division.

Regards,
Bart
