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.
