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 frequencies 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 photolithographic and chemical milling processes and then sealed
within a ceramic package for high stability and low aging.
Available with tight calibration tolerances and high stability over temperature, this crystal is well suited for many
demanding applications.
