According to these specs, can I apply, say, 12 volts AC or must I apply 350V AC? Is that the maximum voltage I can apply? If I apply more what will happen? Spark between the plates? Someone guide me to this please!

What does tolerance mean?

 

That is a maximum rating. Exceeding it will cause failure in the capacitor.

f course you can apply 12 volts. The speedo in your car may go to 120 MPH. That does not mean you can only drive at that speed.

 

Awesome, thank you very much!

 

...Any feedback/suggestion/comment/input is greatly appreciated.

Just to encourage you, I bet a six pack you will not be able to power your house wirelessly.

 

I'll see your 6 pack and raise you a 12 pack.

 

I'm going to do it before I die. If I do, don't live in a house.
