F4JWJ, Pierre on Nostr: npub16jupx…ry8u7 I hadn't noticed that there are now 10µF in 0402 size. 0402 X5R ...
npub16jupxu70nh0pg0wt4maseaf2fg3kv2tgcjal2kaaunms2ltdaxysdry8u7 (npub16ju…y8u7) I hadn't noticed that there are now 10µF in 0402 size.
0402 X5R 10µF 10V have the usual problem of the ultra high density MLCC : insane DC bias induced loss of capacitance.
Just like a shitty Y5V.
It killed me when some Chinese EMS insisted that I change the ubiquitous 100nF bypass capacitor from 0402-X7R to 0201-X5R.
Same DC derating curve :
40%@3.3V
25%@5V
10%@10V.
(The graph % scale is the capacity loss, note the actual value).
