CX3HGSM AT CRYSTAL
9.6 MHz to 250 MHz
High Shock, Low Profile, Miniature
Surface Mount AT Quartz Crystal
Fundamental Mode:
9.6 MHz - 250 MHz
DESCRIPTION
STATEK’s miniature CX3SM 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 land pattern. These rugged crystals are designed
for applications requiring higher shock and vibration survival.

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. 10 ppm MAX for frequencies below 40 MHz. For tighter tolerances and higher frequencies contact
factory.
5. Per MIL-STD-202G, Method 204D, Condition D. Random vibration testing also available.
