 		 #188925 - the cost of testing
Responding to: ???'s previous message
One of the key reasons that extended temperature range components are so much more expensive is precisely because of the extra testing!

They have to test that the chips work to spec under all combinations of all conditions.

It's certainly not a matter of just trying it at -40, does it "work"? = Pass/Fail.
