I decided to use mica and grease in my F5v3 build and so hunted down some really thin mica sheets for use under the Mosfets. I will be using a clamping bar with two M4 bolts one on each side of the Mosfet.
The sheets I obtained measure around 0.0015in. Should I be concerned that they are too thin? Any chance they might crack? How do I determine that they are genuine mica?
Thanks.

Just get regular ones. If they are real you can split them with knife to 4 thin pieces.
The thinner the better.
The thinner the better.
I got them from here. I intend cutting to size. Dont need the mounting hole.

It says condenser mica. Not sure what that is. What do you think? OK?

mica sheet at around 1.5thou/mil is OK, not as good as 1thou/mil.
>2thou/mil is probably too much thermal resistance for any high power device.
If you feel inclined you could try shaving/splitting the trimmed to size sheet down to around a thou/mil for improved thermal performance. If you are very lucky and very careful you might get two thin insulators from one sheet.
Condenser is an obsolete word for capacitor.
Some non english language still use condenser. I suspect that comes from a literal translation from their word for condenser. Dx still talks about condensers in his posts.
"condenser mica" could mean that the mica could be used to create mica capacitors. Silvered mica capacitor is silver plating on two sides of a mica carrier, with leads attached.

Thank you Andrew for your detailed response. I feel more comfortable about this now.
