DESCRIPTION
STATEK’s miniature CX2SM AT crystals in leadless
ceramic packages are designed for surface mounting on
printed circuit boards or hybrid substrates. These crystals
are low profile and have a small footprint. The CX2SM
crystal is manufactured using the STATEK-developed
photolithographic process, and was designed utilizing the
experience acquired by producing millions of crystals for
industrial, commercial, military and medical applications.

EQUIVALENT CIRCUIT
1. Other tolerances available. Contact factory.
2. Unless specified otherwise.
3. Does not include calibration tolerance. The characteristics of the frequency stability over
temperature follow that of the AT thickness-shear mode.
4. 5 ppm MAX for frequencies below 40 MHz. For tighter tolerances and higher frequencies
contact factory.
5. Higher shock version available.
6. Per MIL-STD-202G, Method 204D, Condition D. Random vibration testing also available.
