As per today, JLCPCB has stopped accepting orders for their SMT service. From the website: "From Feb 16th, SMT assembly cannot be ordered. SMT orders placed before Feb 16th will arrange production,but the production time may be delayed 5-10 days.  "

This as a result of the Corona virus.

I sure hope the problems in China (and rest of world) will clear up soon and that no more people will die. What a horrible outbreak!

Edit: They do state that orders placed before the 16th will be done.

I was designing a baord back in november, Looks like that they dropped some components.
I didn't expected that, as far i know ferrite beads are quite common.

All the values 120R and 220R are gone on all packages (0603, 0402, 0805).

I've built my CAD library around basic parts from them.
This is quite unexpected since there is no replacement part for thoose.

At this point I will assemble the whole board by myself.
Sourcing the missing components from another supplier and having to pay two shippimng fees and VAT make the SMT option a lot more expensive.
The important thing is to get involved, and don't give up.

They do change their catalog all the time. I would talk to their support - for example, I recently ran into issues with WS2812B, and they took it off to debug their manufacturing issues (moisture sensitivity in this case), and they said they are planning to put them back on once the issues have been resolved.

They have also added a lot of components recently - ESP32 modules, all sorts of connectors (incl USB-C), some thru-hole components (they hand solder them), etc.

You are badly looking for.

JLCPCB stock:

As was noted, there are ferrite beads.

Some suggestions:
- The JLCPCB library interface is clumsy.  I use https://yaqwsx.github.io/jlcparts/#/ which makes it a lot easier to find components. highly recommended. 
- Design with alternate components in mind.  easy to switch out them.
- Consider partial assembly and complete yourself.  easier than full assembly.

Yea, I'm using that. Time by time I've started to create a Altium component library with the common parts.
Unfortunatly for me a 120 or a 220ohm ferrite bead is userful. Especially for AVDD on MCUs.

I've contacted them they told me that thoose parts are no longer available and they have no idea if they will have replacements.
They now have uncommon values like 11R 26R 300R.

Thy added lots of good stuff I was not expecting a so base component to be missing. They have AVRs and STM32s but no the ferrite to filter the supply forthe ADC...

I found several ferrite beads in 0603 footprint in 120R@100MHz or 220R@100MHz in their catalog. In stock. Nothing in the basic catalog, but the extended list has around 4 different parts for each value.
Everybody likes gadgets. Until they try to make them.

So I got hit with this a while ago (I used a much lower impedance part than I wanted to).  There are 2 categories to search for on their parts catalog.  There are ferrite beads under the inductors, etc category and also beads in the filters category.  And the descriptions in the filters>beads are terrible.

There are only a couple of ferrite beads that are basic parts, both 0805 and in the filters>beads category.
