CX11SM CRYSTAL
16 MHz to 250 MHz
Ultra Miniature
Surface Mount Quartz Crystal
DESCRIPTION
When miniaturization is paramount, Statek’s CX11SM
AT quartz crystal is an excellent choice. Available in fre-
quencies from 16 MHz to 250 MHz, this crystal has a
3.2 mm x 1.5 mm footprint and a height under 1.0 mm.
The resonator is manufactured using Statek’s photolith-
ographic and chemical milling processes and then sealed
within a ceramic package for high stability and low aging.
Available with tight calibration tolerances and high stabil-
ity over temperature, this crystal is well suited for many
demanding applications.
