content: Hi all,Are they any good? It looks to good to be true! From Hong Kong.http://www.ebay.co.uk/itm/400495951810?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649RS-Comp and others have some "cap sample kits" that are way way more expensive.Thanks

content: Yeah, just be aware that the could be Y5V or Z5U which means they could be -20%/+80% capacitance change with voltage and temperature.If you risk getting such chips from eBay, get one that at least says X5R or X7R rated capacitors .. not that they couldn't lie.Good NP0/GOG capacitors are a bit more expensive, for example 45 uk pounds for 5000pcs :http://uk.farnell.com/multicomp/mc0805n470j500a5-08mm/cap-mlcc-c0g-np0-47pf-50v-rad/dp/2112854But even so, buy 5000pcs out of every one and you have 20pcs x 250 kits , 0.18 uk pounds .. you can sell a kit similar to that one on eBay with very good capacitors for maybe 12-15 uk pounds and make a couple of pounds profit.

content: i bought a similar (may be same ?) set from dealextreme - 30 x 10pcs rangig from 1pF to 100nF - they are very tiny. bought them more-or-less out of curiosity(they were dirty cheap - like 2-3Euros the whole set) haven't use them yet, so we'll see later on

content: I bought an ebay assortment of ceramics also - tiny little things, right up to 100nF.... does this have implications to their voltage rating or anything??

content: For assortments of SMT parts, search for '<size> sample book' on eBay. They cost more but having them in a binder is very handy.

content: They are US$35 at Adafruit ->http://www.adafruit.com/products/441,which is pretty expensive shop. On eBay, I was buying them for $10-$15 . Keep looking.
