CX9HT-AT Datasheet, PDF (1/2 Pages) IQD Frequency Products Ltd – Quartz Crystal Specification
ISSUE 1; January 2016
Description
An increasing number of applications require the use of high
temperature crystals. For these applications we offer the
CX9HT 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)
