Description: These are very small surface mount quartz crystals used where size is a concern. Ideal for use with the nRF2401 ICs.

Features:

  • Small 5x3.2mm footprint
  • Operating temperature: -40-85C
  • Frequency Tolerance: +/- 20ppm
  • 18pF load capacitance

  • 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.

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

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

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

  • 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 $1.50 while all the others are only $0.95? Thanks.

  • 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

  • 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.

  • 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.

  • 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.

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

  • 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?

  • 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.

  • the datasheet states ~14.74 MHz. Is this correct?

  • 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 …

    • 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.
