Vendor for (tiny) SMT resonator used on Arduino Pro?

Who makes the tiny resonators used in the Sparkfun Arduino Pro boards?

The SMT resonators I’ve been able to find tend to be much larger!

Thanks

I suspect they’re Murata CSTCE16M0V53.

They’re available through digikey: http://www.digikey.com/product-detail/e … -ND/584635

I’m posting this to an old thread because this is one of the top results for “arduino smt resonator” on google, and it’s not really easily found information.
