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.
