btw, Need any 2" disc piezo ceramic discs 1/16" thick PZT-8 material?
I have a few other sizes also.
Do you know any fun things I could do with them, besides give people
shocks.

Thanks, Mikek

Hi, Mike -

I would like to buy a couple to experiment with and, possibly, learn
something.

How many $ do you want and how do we connect?

Thanks,
John S

Hi John,
My address is good.
These are 2" ceramics, 1/16", they resonate around 1.2MHz as I recall.
We bonded them to 1/16" aluminum for approximately a 660kHz transducer.
We drove them at antiresonance, where they measured around 20 ohms.
We drove them continuous at 250 watts in an ice bath and 1000 watt pulsed.
Send me an email.
