STATEK CX1HT-06 High temperature crystal Datasheet

HIGH TEMPERATURE CRYSTALS
Leaded/High Temperature/High Frequency
DESCRIPTION
An increasing number of applications require the use of
high-temperature crystals. For these applications, Statek
offers the CX1HT-06, CX2HT-06 and CX2HT-07 leaded
crystals. These crystals are designed to operate at
temperatures up to and including 175ºC. The frequency
range offered is 6 MHz to 250 MHz for CX1HT-06 and
9.6 MHz to 250 MHz for CX2HT-06 and CX2HT-07
crystals. The expected life at 175ºC is in excess of 1,000
hours.

1. Tighter frequency calibration available. Contact factory.
2. Other temperature ranges available.
3. Does not include calibration tolerance. The characteristics of the frequency stability over
temperature follow that of the thickness-shear mode.
4. Includes calibration tolerance.
5. Higher shock and vibration available.
