What's this peice called?

I was recently soldering my CC3000 whenever this piece popped off the board. I’m looking to buy a new one, but I have no idea what it’s called!

Bonus points if you can link me to a place where I can buy the piece.

It is probably a small resistor.

Can't you solder the old one back on again ?

I forgot to mention, I lost it.
I was keeping it safe in a plastic bag for a few days, and somehow I managed to lose the bag.

EDIT: No, it's not a small resistor, but it's pretty close.

That is a capacitor. It looks like, by placement, it may be a bypass capacitor on the 3.3V regulator. Your best bet is to ask Adafruit.

See page 44 of the PDF, it has a schematic of the board. Perhaps you can trace some of the PCB traces back and figure out which capacitor this is.

Wow, that is freakishly faded.

Bottom left corner of this PCB pattern, it does appear to be one of the bypass capacitors. One end to ground, the other end to the tab on the regulator.

Looks like a ceramic capacitor that hooked between the 3.3V and Gnd of the regulator. It's not labeled on the silkscreen but you can see on the schametic that it's probably one of the 10uF caps. (https://learn.adafruit.com/system/assets/assets/000/010/985/original/adafruit_products_cc.png?1379351147). I don't know whether its 0805 of 0603 though.

You can buy them off of Digikey or Mouser, whichever you prefer.

0805 size

0603 are a lot more money, doubt it was used

kinda scarry that the solder holding the cap would get hot enough to have it melt off.

Drawing too much current, blame the operator :wink:

Maybe put one of these on the regulator.

Adafruit is an evangelist of open source, and AFAIK all their boards have online schematics and pcb layout files.

It’s a 10uF 0805 ceramic cap (C7) on the 3.3V regulator output.

There speaks someone who's never worked with surface mount components...

Resistors are white with a black film on top with writing printed on them. Ceramic
caps are brown or sometimes white and never have writing on them.

Yep, that looks very much like a 10µF MLCC to me. I generally use 1206 on my regulator outputs (and inputs) rather than 0805. The larger solder area takes more heat to melt it off :wink:

I buy them on reels by thousands.

I just bought 50 of http://www.taydaelectronics.com/capacitors/100pf-50v-smd-ceramic-chip-capacitor.html
Hopefully they'll work!

I'm sure they will work, yes, there's nothing really to go wrong with them. However, will a 100pF capacitor work as a replacement for a 10F one? Given that they are 1/100000th of the value, I would guess not.

Try ordering some of the right value next time.

That problem could be reduced by stacking all 50 of them :wink:

If he can't keep 1 on the board, I don't there will be much better results with 50 8)

tayda doesn't carry 10uF chip caps, the biggest is 0.47uF

Just received the pieces in the mail, and it didn’t work. I have a recommendation from Adafruit, so I think I’ll just still with their opinion.

Didn't work? What's that mean?

The pieces? You mean the wrong pieces you ordered at first, or the right pieces we pointed out to you on other sites?

Wait... What? It can't not work... It's just a bypass cap, technically it should work without it... (However poorly.)

What's more likely is that something overheated and was permanently damaged.
