Hi everyone,

I'm searching for a varistor with an insulation resistance of min. 7GOhm.
Are there varistors with this property?

Thank you in advance, Uwe.

Varistors runfrom a few ohms to hundreds of Kohms.

There are *resistors* available in the 10^10 ohm region that you
mention, but they are not cheap.
Now if you want (say) a 1K varistor, and need insulation around it,
that is a different story.
If so, you should specify the "why" of 7*10^9 ohms or better.
For low leakage to other components?
To stand off high voltages: a few KV or hundred KV or more?
