Thanks for the explaination. One more question- I bought several
large caps at a freight damage type store. They are rated for 525V
and 3500MFS. They have the screw type ends and are very large (9 in
long!) Would these be too large? From what I've read they should be
fine, but most people probably don't run into caps like these every
day. (I actually tried one out on another project that used a 12V DC
motor to run a hydraulic pump and it worked great) Just wondering if
there would be any ill effects other than the cabinet space it would
occupy. New to this electronics stuff, but loving learning something
new!
