Where is high value ceramic capacitors?

In a project, I am using the PTN78020H: http://www.kynix.com/Parts/3576609/XG7.html power supply, and it has a recommended circuit (from the datasheet linked above) that looks like this: Circuit diagram for power supply

Now on the input, it requests a massive 4 x 4.7uF ceramic capacitors. I’ve had a look around and haven’t found any place selling through whole ceramic capacitors in values anywhere near that.

Typically a ceramic cap is used to filter high frequencies, and electrolytic have much worse performance, so I don’t want to switch all the input caps to electrolytic, but would it be feasible to, say, use 10uF electrolytic and 1uF ceramic? Tantalum caps come in the 4.7uF capacitance range, and I believe have better performance than electrolytic?

My question is pretty much: Assuming I can’t get hold of 4.7uF ceramic capacitors, what should I do?

Maybe I do not understand the problem but when I search eBay for ceramic 4.7uf i get lots of results like http://www.ebay.ca/itm/100-pcs-4-7uf-50v-ceramic-multilayer-monolythic-NP-capacitors-/381221264885?hash=item58c28eddf5:g:1z8AAOSwBLlVJs8G

Edit: Digikey lists 215 different 4.7uf through hole capacitors https://www.digikey.ca/products/en/capacitors/ceramic-capacitors/60?k=ceramic+capacitor&k=&pkeyword=ceramic+capacitor&pv69=80&FV=ffe0003c%2Cmu4.7µF|2049&mnonly=0&ColumnSort=0&page=1&quantity=0&ptm=0&fid=0&pageSize=25
