CX1HT EXT

Quartz Crystal Specification

ISSUE 1; January 2016

Outline (mm) -SM1 = Gold plated (RoHS)

Description

An increasing number of applications require the use of high

temperature crystals. For these applications, IQD offers the

Statek CX1HT 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 530kHz to 2.1MHz

-SM1 Gold plated (RoHS)

-SM5 Solder dipped (RoHS)

Please note that all data is only valid at 25°C unless otherwise

stated.
