Yes, don't use the barium type at Tesla frequencies.  Use strontium 
titanate.  They don't overheat.

MMC are still the very best for small and medium sized coils.

I e-mailed the manufacturer they were 'RF rated barium titanate doorknob
capacitors'. It doesnt make sense to me at all. I suspect someone made a
mistake, and have a strong feeling thay they ARE NOT RF rated...
