'[OT] Prototype quantities'

I thought, great, Farnell has what I want, only 21p each, 1uF 100V ceramic (actually I'd like 200V and 400V 1uF and 2uF caps too that work in 19kHz SMPSU). I'll order 20 to try out the idea ( A Cuk SMPSU for 75V DC from 7.5V DC in)

Order them and it's free delivery, in Stock UK, rather than £XXX because it's USA stock.

But two days later they cancel the order (after taking my money, and confirming the order by email), I must order on the Irish Web site. But the Irish Web site has a minimum order of €20

So where do I get small quantities of stuff without Mega postage or Minimum order to Ireland?

The Hong Kong / Thailand / China /Taiwan etc eBay lads can do it but variety is limited.

Mouser and Digikey seem very expensive and awkward for small orders to here, so as result I've never used them. Years ago I used to get a lot from Farnell, but then it was the the UK Office.

Radiospares ?? (<http://uk.rs-online.com/web/>)

They don't seem to have an Irish branch so the UK one may be OK.

I have the same problem. Too expensive to order small quantities

My advice is to keep a stock of basic prototyping components and keep a list of what components you are getting low on. Then when you do need to place an order for some special part you can bulk it up by adding the components you are getting low on

Oh they have had an Irish branch on the Herberton Rd in Dublin since
forever. Called Radionics. No, I can only order from the Dublin office
and they are often madly expensive, I gave up using them about 5 years ago.

http://radionics.rs-online.com/web/

In X7R 100V 1uF they only have through hole (That's OK, I can use TH or
SMT) but  packs of ten and €2.739 each, i.e. 27 Euro a pack
These things ARE more expensive at 100V than the usual 10V for a 1uF,
and X7R is more expensive than Z5U, but still that price takes the micky.

Or SMT for €1.20 each (pack of 5) and 97c each in pack of 25. Still
about x5 what it should be.

Their search is rubbish. 5mins later I see they have 1uF 100V X7R murata
at 40c each. Only about twice a reasonable price :-)


723-6827          20          Ceramic SMT capacitor 1uF 100Vdc
Available for despatch within 24 hours
       Each (In a Pack of 10)          €0.404          €8.08
         Running Total        €8.08
Delivery Charge        €4.40
V.A.T        €2.62
Order Total        €15.10


Far too expensive for supposed local post of a tiny packet of 15c parts

I have a great stock of SMD and Leaded parts.
But now redundant and no money.

So if I can't get exactly what I need cheap, then I don't get it at all. Obsolete parts from Asia are great value.
Maplin is very convenient, we  even have one  10min away. But they make RS look very cheap. I can get 20 to 100 parts from Asia inc postage for price of one from Maplin.

Where do buy from in Asia under such terms?
That may be attractive to me.

I can get volume parts in Asia at good prices but small volumes are not so good.
I have a HK company that will sell 1 or few items but charges about RS prices.
Whih is fair but not useful.

So an Asian seller who MAY have things that are useful could be good.

Probably I have no info of value to you!


Random eBay sellers. It's almost always what looks to me to be left overs from production that ended or Old Stock.

Hence no 1uF 100V ceramics, but loads of DIL ics used in old VCRs, CD players etc ... :)

Not reliable for repeat orders, when it's gone it's gone :)

E.g. Random stuff in my watch list (not all especially cheap, but types of seller)

I'm tempted on some of these for PIC to drive stuff... inc VFDs

I'm making a bit of test gear with big VFD display and was going to use "octal" level shifting drivers

I'd forgotten them. They are unblocked in my no-script, so obviously I looked before. Don't think I ever bought there.

Why not check out BGMicro in the US and possibly Rockby clearance stock in Australia, though freight costs might outweigh and cost benefits.

50V seems the highest voltage 1uF Ceramic they have. But it's hard to be sure as their search (direct or parametric) is very poor compared to Farnell.

These would be nice if 100V but 50V isn't enough for a 75V supply.
http://cgi.ebay.ie/200pcs-1uF-1-uF-105-50V-Mono-Monolithic-Capacitors-/150593575975

€14 inc postage for 200.

I have a bunch of 1uF chip ceramic. But I'm sure that they are 15V to 50V, not 100V (no idea of rating, part of a cheap selection box in interlocking plastic boxes with flip lids).

I thought that I read that Digikey would sell with free shipping and no minimum with prepaid mail orders & no credit cards.
Perhaps that was US only.

Digikey needs a £50 (~US$70) order to get free shipping to the UK, Michael is in Northern Ireland I believe, which is part of UK.

Not since 1983,

I'm in the other bit.

But no doubt the same principle.

Ah, OK, I hadn't really picked up any pointers to just which 'half' you were really in. If there have been pointers in the past I have either missed or forgotten them, sorry.

> But no doubt the same principle.

Yeah, I suspect from their shipping POV it is the same.
