MMD Components (Monitor +ACY- Quartztek) has produced what they claim is the smallest quartz crystal available in production quantities. Measuring only 2 x 2.5 mm, with a 0.57-mm profile, the X series surface-mountable crystals can be used in any application where space is limited and a frequency reference is required. They are available for frequencies from 16 to 60 MHz with frequency tolerance/stability rate as high as +ALE-50 PPM/+ALE-100 PPM. The units are fully RoHS compliant and compatible with lead-free reflow profiles. They are supplied in a hermetic four-pad ceramic package and delivered on tape-and-reel packaging for use with automated assembly equipment. MMD Components (Monitor +ACY- Quartztek) (www.mmdcomp.com)
