HIGH TEMPERATURE CRYSTALS High Temperature/Low Frequency DESCRIPTION An increasing number of applications require the use of high-temperature crystals. For these applications, Statek offers the CX1VHT/CX1HHT, CX4VHT, and CX9VHT crystals. These crystals are designed to operate at temperatures up to and including 200ºC, and feature an expected life in excess of 1,000 hours at these temperatures. The frequency range offered is 10 kHz to 600 kHz for CX1VHT and CX1HHT crystals, 30 kHz to 250 kHz for CX4VHT crystals, and 32 kHz to 160 kHz for CX9VHT crystals.
