CX103 CRYSTAL
530 kHz to 2.1 MHz
Miniature Quartz Crystal
Fundamental AT
-Cut Quartz Crystal
DESCRIPTION
The CX103 quartz crystal is a high quality miniature AT cut
quartz resonator. The CX103 is hermetically sealed in a
rugged, miniature ceramic package, one-fourth the size of
an eight-pin mini-DIP. The CX103 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.

PACKAGE HANDLING
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 175
o
C,
glass lid to package seal rim temperature should not
exceed 210
o
C.
If the seal rim reaches temperatures above the
maximum specified, the package may lose its hermeticity
resulting in degradation of crystal performance. Mishandling of
CX crystals can cause cracking of the glass lid and loss of
hermeticity.
