Re: [TCML] ESR ESL figures in caps

["Chris Swinson" <list@xxxxxxxxxxxxxxxxxxxxxxxxx>]

Hi Bert, all,

May seem a daft question, though what about current ratings of caps, if I 
have an array of caps rated at 800amps each, does the array add up in amps 
terms or is it still 800amps regardless of number of caps ? I've always just 
assumed they add.....

Cheers,
Chris
