HIGH TEMPERATURE CRYSTALS High Temperature/Low Frequency CX1VHT/ CX1HHT 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. 10 kHz - 600 kHz CX4VHT CX9VHT 30 kHz - 250 kHz 32 kHz - 160 kHz FEATURES DIMENSIONS High temperature operation up to 200OC High shock resistance Hermetically sealed ceramic package CX1VHT/ CX1HHT MAXIMUM APPLICATIONS Industrial Downhole instrumentation CX4VHT MAXIMUM CX9VHT MAXIMUM DIM inches mm inches mm inches mm A 0.330 8.38 0.210 5.33 0.170 4.32 B 0.155 3.94 0.085 2.16 0.068 1.73 C (SM1) 0.070 1.78 0.050 1.27 0.038 0.97 Rotary shaft sensors C (SM5) 0.075 1.90 0.053 1.35 0.040 1.02 Underground boring tools D 0.055 1.40 0.046 1.16 0.038 0.97 E 0.070 1.78 0.020 0.51 F 0.070 1.78 0.025 0.64 PACKAGE DIMENSIONS CX1VHT/ CX1HHT CX4VHT CX9VHT CX4VHT CX9VHT SUGGESTED LAND PATTERN CX1VHT/ CX1HHT 10183 Rev A STATEK CORPORATION 512 N.

For more detailed specifications on low frequency crystals, refer to standard crystal datasheets (CX1VSM, CX1HSM, CX4VSM and CX9VSM.) 2. The motional resistance of a 32.768 kHz CX4VHT crystal at 200ºC is approximately 1.6 times that of a 32.768 kHz CX4VSM crystal at 25ºC. Contact factory to obtain information on this and other parameters for low-frequency crystals in other packages and frequencies at 200ºC.
