Samsung MLCC characteristics data

Hi, all,



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 in



0805. 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:



formatting link
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.



Cheers

Samsung is known for producing caps with high density, but horrible C vs V rating

But the data given for CL21A475KPFNNNE seems not so bad. Do other 0805

4u7/10V behave substantial better?

Any idea for a better MLC capacitor specification than xuF/yV ? C@Vmax? Energy (U*U *C/ 2) ?

It's about 3.5 uF at the rated 10 volts. That's actually not bad.

For a one-point-seven-cent cap, it's practically miraculous.

Bought a reel, just in case -- BTW, that one-point-seven-cent is a ripoff :) Avnet has 292,000 (290,000 already) in stock for $15.40 plus $3.54 tariff per reel that comes to ZERO-point-nine-forty-five-cent out of the door :)

Why do people bother to make passives for under a cent and fabulous transistors for three cents?

Because it lets them sell a lot of them. Sell enough of them and you can make millions, and it's hard for the competition to undercut those sorts of prices.

For three cents each, of course.

A modest CPU nowadays can have a billion transistors under $100, so the Intel i3 comes in at 0.000 007 cents per transistor. That's better than the per-letter price of my Sunday paper.

Because they know they can oversell quantity, by orders of magnitude, to low-volume users?

Used to be, you'd sniff out high-volume parts in a range and ride on the pricing coat-tails of the high-volume purchasers, but at a sensible quantity for the job.
