HIGH TEMPERATURE CRYSTALS High Temperature/High Shock/High Frequency DESCRIPTION An increasing number of applications require the use of high-temperature crystals. For these applications, Statek offers the CX1HT, CX4HT, and CX9HT crystals. These crystals are designed to operate at temperatures up to and including 225ºC. The frequency range offered is 6 MHz to 250 MHz for CX1HT and 14 MHz to 250 MHz for CX4HT and CX9HT crystals. The expected life at 200ºC is in excess of 1,000 hours.
