CX11L TELEMETRY CRYSTAL
16 MHz to 250 MHz
Low Profile,
Ultra-Miniature
Surface Mount Quartz Crystal
DESCRIPTION
When miniaturization is paramount, Statek’s low profile
CX11L AT quartz crystal is an excellent choice. Available
in frequencies from 16 MHz to 250 MHz, this crystal has
a typical footprint of 3.2 mm x 1.5 mm, and a typical
height of 0.5 mm. The resonator is manufactured using
Statek’s photolithographic and chemical milling process-
es and then sealed within a ceramic package for high
stability and low aging. Available with tight calibration tol-
erances and high stability over temperature, this crystal
is well suited for applications that have a space restraint
and require a crystal with a low profile.
