CX11SM CRYSTAL 20 MHz to 50 MHz Ultra-Miniature Surface Mount Quartz Crystal Actual Size DESCRIPTION When miniaturization is paramount, Statek’s CX11SM AT quartz crystal is an excellent choice. Available in frequencies from 20 MHz to 50 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.
