CX1H CRYSTAL
10 kHz to 600 kHz
Miniature Quartz Crystal for Series Oscillators
DESCRIPTION
The CX1H quartz crystal is a high quality tuning fork
resonator for use in Series (two cascaded inverters)
oscillators. The CX1H is hermetically sealed in a rugged,
miniature ceramic package, one-fourth the size of an
eight-pin mini-DIP. The CX1H crystal is manufactured
using the STATEK-developed photolithographic process,
and was designed utilizing the experience acquired by
producing millions of crystals for industrial, commercial,
military and medical applications.

The CX crystal is hermetically sealed in a ceramic package.
Normal handling and soldering precautions for small, low
thermal mass parts are adequate when installing or testing CX
crystals. CX crystals may be wave soldered, with proper
precaution taken to avoid desoldering the leads. A slow
machine rate or too high a pre-heat temperature or solder bath
temperature can damage the crystals. Lead to package
solder interface temperature should not exceed 175oC,
glass lid to package seal rim temperature should not
exceed 210oC. If the seal rim reaches temperatures above the
maximum specified, the package may lose its hermeticity. Loss
of hermeticity results in a frequency decrease and motional
resistance increase.
