In many cases supply voltage is filtered by combinations of small (1n-100n) ceramic and larger (say 100uF) tantalum/electrolyte capacitors.
Since each extra component requires some space around it for manufacturability I was wondering whether there are
hybrid capacitors that combine two types (low ESL, large capacity)
capacitors in one package. Of course, it would need a special landing pattern in order to preserve the low inductivity.
Price would be higher and the question which combinations would
be appropriate, but the space savings could open a marker for mobile devices, medical, etc.
I found this article, but it discusses ceramic-only:

Maybe I missed it, and something like this exists already?
