content: Recently I bought a lot of smd reels and there are too many 50V 100nf 0603 caps on it, so I'm selling these,https://www.digikey.com/product-detail/en/murata-electronics-north-america/GRM188R71H104KA93D/490-1519-2-ND/587143Reels are clean and unused, each reel of 4000 units for 10€, 10 reels available, postage not included.Sale ended

content: Quote from: MasterTech on October 17, 2018, 04:34:15 pmYou provided digikey link, so for some reason I first read it like "I bought from digikey". It's just that you may think twice before using them for production. They may be not as solderable as fresh parts. Depends on component itself and storage conditions.

content: Quote from: MasterTech on October 17, 2018, 04:54:30 pmDon't get me wrong, I think that's a reasonable price with current MLCC shortage. They may solder just as well as fresh parts, or may not.

content: Quote from: wraper on October 17, 2018, 04:43:33 pmI agree. These are good for prototypes but probably not for production runs using reflow soldering.

content: Quote from: MasterTech on October 18, 2018, 05:38:04 amDid I ever say their parameters could deteriorate? It has nothing to do with solderability. What matters how terminal surface finish was made and storage conditions. I've seen plenty of parts which were 4-5 years old and solder like crap or 20 year old parts which solder excellent. What you measured is rather high, caps like X7R loose more than 10% of their capacitance with time (ageing) but process is completely reset with heating (soldering).

content: QuoteThey have 10% tolerance. Take ageing in account and 80nF probably would still be within tolerance given the age. Heating/soldering returns capacitance to initial value.QuoteI just don't get why you are so agitated about all of this? Basically the only thing I concerned in what I wrote is that it would be proper to mention they are NOS.Here is example how I "sell" parts with dubious origin.https://www.eevblog.com/forum/buysellwanted/31-pcs-attiny24-(soic-14)-for-the-cost-of-shipping/

content: Quote from: austfox on October 19, 2018, 05:42:50 amObviously not used them all at once. But I guess it is a well known fact right now that Caps are somewhat rare at the moment... Since the price was very good I would have stocked those since I can't get my hands on new caps for a reasonable price right now.Quote from: MasterTech on October 19, 2018, 07:01:45 amI guess it was a good thing that I didn't get the chance to buy anything from you

I struggle to see how anyone who is reflow soldering a production run of PCBs would be scouring these forums to obtain a ‘deal’.

content: Nobody talked about big production runs.I tend to stock Stuff that I know will be usefull soon or is somehow rare and could be of some value in the more or less near future. However, I don't run after someone who doesn't want to sell his stuff.

content: Quote from: austfox on October 19, 2018, 05:42:50 amI got to admit, I wonder what kind of characteristics you could get from 400uF @ 100V of MLCC capacitors.

content: Quote from: Ysjoelfir on October 20, 2018, 05:09:49 pmBut why would you need 20000 capacitors? Over time parts get more difficult to solder especially if they are stored in poor conditions. A while ago I bought a reel of 100nf capacitors myself but only because that was the only available option to get some 100nf capacitors. I don't think I'll use all of them. Going through 1000 pieces takes me a few years let alone 4000 pieces.
