DESCRIPTION FEATURES DOCUMENTS

These are very small surface mount quartz crystals used where size is a

concern. Ideal for use with the nRF2401 ICs.

20ppm * 18pF load capacitance

Crystal SMD 16MHz Product Help and Resources

SKILLS NEEDED

Core Skill: Soldering

This skill defines how difficult the soldering is on a particular product. It might be a couple simple solder joints, or require special reflow tools.

Skill Level: Competent - You will encounter surface mount components and basic SMD soldering techniques are required.

See all skill levels

Core Skill: Electrical Prototyping

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and

know the ins and outs of electronics.

Skill Level: Competent - You will be required to reference a datasheet or schematic to know how to use a component. Your

knowledge of a datasheet will only require basic features like power requirements, pinouts, or communications type. Also, you may

need a power supply that?s greater than 12V or more than 1A worth of current.

I’m still looking for an 8Mhz version of this crystal for a 3.3v Arduino Pro Micro circuit ( Atmega32U4 ) I want to

build into my project. Any help? For now I need to know if the SMD footprint would be the same as this one, but

I’ll obviously need to source the component eventually too.

juliusbangert / about a year ago / 1

Is there an equivalent sized 8MHz one ?

1TekPro / about 2 years ago * / 1

Interesting how multiple people have asked if external caps were required and no answer as of yet… Yes,

external caps are required. The size is based on pin cap of the microchip being used. Example: CL of this

crystal is 18pF and the parasitic+input capacitance of Atmega328 is 10pf per pin

18pF(CL) = (C + 10pF(pin cap))/2

C = 26pF

So in short, you will need 2 - 26pf external capacitors.

DATASHEET HAS COMIC SANS!!!!

I hope you aren’t doubting the integrity of product specifications. Item 2.2 of the Environmental &

Mechanical specifications clearly states, Ahem. “2.2 Shock: drop freely from 75cm height 3 times on

30mm thick hard wooden board.” You just can’t argue with science.

The last 2 times I’ve ordered this, it has not been the 5x3.2mm footrint crytstal, but rather a 6x3.5mm crystal.

They are not interchangeable, so watch out! Hopefully this will be corrected soon.

darrylh / about 3 years ago / 1

Same here. I was expecting the same one that’s in the Crystal Kit.

djmason9 / about 4 years ago / 1

In case anyone is interested I have made a sketchup 3D model of this component

Toni_K / about 4 years ago / 1

We’d love to add that to our GitHub repo here if you don’t mind.

e-radionica / about 5 years ago / 1

Does this crystal need external caps or I just need to connect ground pins to ground at PCB layout?

e-radionica / about 5 years ago / 1

After fabricating 200pcs of PCBs I have learnt that it needs. :( 22pF works perfect.

UNTEngineer / about 5 years ago / 1

FYI, if anyone is interested in getting this in bulk, Mouser carries it: ABM3B-16.000MHZ-B2-T

0xdec / about 5 years ago / 1

I know this has been asked before, but do the two ground/case pins need to be connected to ground? Also,

why is the 16Mhz crystal while all the others are only ? Thanks.

stevenvh17 / about 3 years ago / 1

In crystals smaller = more expensive.

Member #405467 / about 3 years ago * / 1

But the 24Mhz and 12Mhz SMD crystals are while this is . I don’t think TheInventor was talking about

the normal crystals vs the SMD ones. I can only guess that the price difference is due to the order

size SFE buys these in, or that the distributor sells them in.

Edit: The datasheets indicate these are sold 20k per box, while the other two are sold 10k per box.

SFE may not buy in those quantities though.

Do you prefer these to: CSTCE series? Any advantages with this one except for being larger? which took me a

little while to get used to hand solder on your eagle pads… They don’t quite line up lol

Thimplum / about 6 years ago / 1

Help! Does anyone know of a Fritzing part for this? I’m designing a 2.4ghz wireless board, and need to use this

instead of its through hole counterpart. The “SMD Crystal” that come with Fritzing looks nothing like this.

duckythescientist / about 7 years ago / 1

I have one of these that seems to have died in a project after a few weeks of operation. I don’t know if it died

because of poor soldering (or overheating) or if it died because the SF Eagle library didn’t have the other two

pins connected to ground. I, too, would like to know if the pins need to be grounded or if they may be left

floating.

Member #105537 / about 7 years ago / 1

I don’t see this in the eagle library (and I just downloaded the new one today). If it is in there, what’s the name.

ThinkerT / about 7 years ago / 1

Could this be used on a arduino copy board? I ordered some and now i see there are four pins…

arduinoboy / about 7 years ago / 1

yes i think so

Saraneth / about 7 years ago / 1

The Datasheet lists the load capacitance as being 18pF and you have it listed here as 12pF. For maximum

stability in my project which is it?

iklln6 / about 8 years ago / 1

heads up to anyone milling/etching their own board – the datasheet for this part showing the pads is LOOKING

FROM THE BOTTOM. When looking at this crystal from the top, the upper Right and lower Left pads are the

crystal pads, while upper Left and lower Right are ground.

[GND]…………………………[X1]

…………………top………………..

[X2]…………………………[GND]

zhivko / last year / 1

Would it be wrong to leave both GND pads floating ? I am looking at: http://www.mouser.com/ds/2/417/7c-

5562.pdf And they have: PAD:FUNCTION 1:ENABLE CONTROL 2:GND 3:OUT 4:VDD

Is pad function following some standard ?

SlyVixsky / about 8 years ago / 1

the datasheet states ~14.74 MHz. Is this correct?

EmbeddedMan / about 8 years ago / 1

To SparkFun Eagle Library Maintainer (somebody must have that title, right?),

The two ground pins on the Eagle footprint for this part are not connected to ground. Is this intentional, or just

an oversight? It seems like they should be …

kellenjbBTC / about 7 years ago / 2

I have used this crystal before and have always connected the pins to ground. It is a pain to change the

eagle part to having its ground pins connected. It would be nice if sparkfun fixed this.
