# [TCML] Microwave caps

```I believe he's referring to the fact that these caps will definitely handle more than they're rated for. Not that I would (or would be allowed to) exceed their voltage ratings by much. I read on the 4hv site link that his MWO cap was rated for 1700 v, but failed after repeated firings at 10,000. However, like I said,  I don't think I'd like to tempt fate with these things.

Point of fact, most of my caps are around .70, resulting in more capacitance = more power, right?

Another few questions for someone to answer, or direct me if they could:
1. Is there a comprehensive tutorial, or schematic, or something on how to build a coin shrinker?
2. Is it bad to "gang up" capacitors with different capacitances and/or voltage ratings?
3. In a coin crusher, does the coil that does the crushing have to fail? Can it be made not to?

As always, any opinions are welcome and helpful!Sincerely,
Joel Torgeson

Jim -

I don't understand your post; can you explain the math? How did you arrive
at the "10kv" rating? With five series-connected caps per string?

Joel's caps are predominently .5uF at 2,100V.

(Incidentally, the unit of energy is "joule".)

Herr Zapp
