Typical Parameter Values:
This surface mount low profile package offers exceptionally low volume with only 1.3 mm
height requirement, perfect for dense layouts or low headroom. The AT-Cut device has the
same favorable temperature characteristics as the MP or ATS parts, but with a fraction of
the volume, ideal for PCMCIA applications or other space-premium designs.
