Many of us have been frustrated by Samsung's continually hiding its MLCC characteristics data, so that even their own search engine frequently can't hide it.
For instance, the CL21A475KPFNNNE is listed as 4.7 uF, 10%, 10V, X5R in0805. Digikey has over 800k in stock, and will happily sell them to you for under 2 cents in reels. Not bad at all, assuming their C(V) is vaguely decent, but is it? The characteristics links are broken again!
One approach that seems to fix this is to take the part number, chop off the last character (the package code), and make it into a URL, like this:That pulls up a useful summary page with the relevant plots, showing that the capacitance is 70% of nominal at 5 volts--not bad for such a high-density part.
Dunno how long this trick will work, but it seems good for now.
