Quartz Crystal Specification
CX4HT AT
ISSUE 1; January 2016
Description
An increasing number of applications require the use of high
temperature crystals. For these applications we offer the
CX4HT AT. These crystals are designed to operate at
temperatures up to and including 225ºC. The frequency range
offered is 14MHz to 250MHz.
The expected life at 200ºC is in excess of 1,000 hours.
-C-SM1 Gold Plated (RoHS)
-C-SM4 Solder Plated (RoHS)
-C-SM5 Solder Dipped (RoHS)
FEATURES:
High temperature operation up to 225°C
High shock resistance
Hermetically sealed ceramic package
APPLICATIONS:
Industrial Downhole instrumentation
Rotary shaft sensors
Underground boring tools
Please note that all data is only valid at 25°C unless otherwise
stated.
