who's eating all the 100nF 0603 caps?

[tron9000]

I don't know if anyone else has noticed but go a search for 0603 0.1uF caps from either digikey, farnell or RS or whoever you use...

...where have they all gone?!

plenty there

Check the RS lead times. October/December on anything other than noddy quantities.

Also all the 120nF ones are gone now as well.

[tron9000]

plenty there

if you want to wait till october!

[bd139]

Found some. TME has Yageo ones in half mil quantities: https://www.tme.eu/en/details/cc0603krx7r7104/0603-mlcc-smd-capacitors/yageo/cc0603krx7r7bb104/

try maplin 

I only ordered 10 100nf tants the other day with no issue

Lot of components get long leadtimes, economy is booming, factories are running 24/7.

Need a couple of thousand

Here's the guff from a Farnell Agent

You may be aware that there is currently an unprecedented global demand on certain electronic components.  The biggest impacted technologies are SMD, MLCCs and SMD resistors. This is due to the current scale and usage of smart technologies and the automotive industry, and has led to highly extended lead times and allocation on some products we supply.

Our Purchasing and Support teams are working hard with suppliers and manufacturers to establish confirmed supply dates and, where possible, seek alternative products for our customers.
 
We appreciate your understanding during this period of globally increased demand on our products and hope to reassure you that as a business we are doing all that we can to bring stock in as soon as possible.

Please also be aware that this is a global issue and is not unique to Farnell as a business. We endeavor to provide stock on the promised dates but this may fluctuate

I think I smell BS....this has never been a problem before?

[bd139]

That smells like someone just paid more than Farnell were willing to.

[bob225]

Mouser has plenty stock, your have to take a hit on the shipping charge

I rather smell someone has no clue. There is a thread about this on the forum. https://www.eevblog.com/forum/projects/has-the-world-run-out-of-100nf-caps/
As well you might use google to find out.

I would not say plenty, the vast majority of part numbers are not available and prices are much higher than a year ago.

that's why I'm here....think i'd be asking if i did? thanks for your links.

[tron9000]

further more I've just been talking to an assembly house. They said they were told a "while ago" to stock up on any passives starting with a 1...kind of implies this was forseen?

[VK3DRB]

As someone who works in the electronics industry, I can tell you there are definitely lead time problems with many otherwise rather common components.

[tszaboo]

Yes,  I got confirmation from multiple sources for passive component shortage. I have too look up alternative components on a daily basis, because they cannot confirm component sourcing months from now. It is really bad, I am considering to tell my boss, to expect prototypes delayed, because I cannot find stupid things like resistors in the right size. And this will last at least till next year.

[nctnico]

I don't know if anyone else has noticed but go a search for 0603 0.1uF caps from either digikey, farnell or RS or whoever you use...

I had to buy a reel with 4000 pieces from Farnell a while ago. There wasn't any other alternative (except for buying more than one reel). It has been like this for a couple of months.

Include me in this group.
In my corporation, we have a dozen assembly facilities spread across three continents.
I have a good acquaintance just went to the headquarters to discuss electronic component sourcing issues. He told me that many components are either on allocation or have huge lead times.

Part of my job is to find substitutes for these scenarios. And indeed, I've had to use the trick to replace 0.1uF caps with 0.15uF or 0.2uF. Or in less-than-critical circuit applications, I go down to a lower value.

Resistors are facing similar issues. Here I've substituted 5% tolerance devices with 1% tolerance.

The big problem is of course, complex ICs. Our engineering, like most engineering departments, likes to stick with a particular microcontroller brand, as you have a single tool set which everyone is intimately knowledgeable with.
But lately we have diversified to other three microcontroller vendors, for the same reason: many popular microcontroller types, specifically those used on the automotive environment, are on allocation. If you are not Ford, Toyota or VW, most likely you will be on allocation.

[mbless]

The most annoying part for me is that the capacitors that are left are absolutely appalling in terms of DC bias. I've had to spend multiple hours finding replacement capacitors, and in the end I've typically had to increase the package size 

[free_electron]

There is a worldwide shortage of MLCC caps as the three largest manufacturers are abandoning certain of their product lines to allocate production to more lucrative series. In essence : they stop making the cheapo stuff to make more lucrative parts (if you still don't get it : parts that are higher spec and go for more $$.)

I just saw a 1uf 16v 0805 with 56 weeks lead time ...

The same is happening for resistors. All that thick film stuff ? tata bye bye ...

In around 1994/5 it did big time, everyone was talking about the "spot market", big telecom elephants was affected and bought  from grand/pa/mom backyard outlet to get hold of components, that time it was mainly semiconductors and some passives i recall.These spot market suppliers made big time money from nothing, the prices for some components was just baffling.

[schmitt trigger]

That was triggered in part by a Sumitomo plant fire in Japan, which provided the semiconductor encapsulation resins for about 2/3 (or something in that ballpark) of the world's semiconductors.

Hmm, but that would mean they give all that business to their competitors instead? or ar you saying there are basically only three manufacturers of MLCC caps?
