IC PHC series cap - good low ESR cap?
I'm always on the lookout for good low ESR caps, and ideally non-electrolytic. Can someone comment on IC's PHC series metallized polyprop film caps? I'm specifically thinking for duty as the cap immediately following a series pass regulator. Useful 4, 6.8, and 10 uF sizes at 600V. ESR in the 0.0034 - 0.0065 ohm range.

Newark catalog page featuring the PHCs - mistake for the 10uF, 600V cap's ESR according to the data sheet (follows..)

Yamamoto uses them in PS ! Good caps in my opinion

What's the actual DC voltage of the application? The lowest ESR caps that's not electrolytic are stacked film or ceramic type.
