CX4HT-EXT 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, IQD offers the
Statek CX4HT EXT crystal. These crystals are designed to
operate at temperatures up to 200ºC, and feature an expected
life in excess of 1,000 hours at these temperatures. The
frequency range offered is 600kHz to 2.5MHz
-SM1 Gold plated (RoHS)
-SM5 Solder dipped (RoHS)
Please note that all data is only valid at 25°C unless otherwise
stated.
