PACKAGE DIMENSIONS
DESCRIPTION
The CX-1V quartz crystal is a high quality tuning fork
resonator for use in Pierce (single inverter) oscillators. The
CX-1V is hermetically sealed in a rugged, miniature ceramic
package, one-fourth the size of an eight-pin mini-DIP. The
CX-1V 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.
FEATURES
Miniature tuning fork design
High shock resistance
Designed for low power applications
Compatible with hybrid or PC board packaging
Low aging
Full military testing available
Ideal for battery operated applications
Designed and manufactured in the USA
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. Loss
of hermeticity results in a frequency decrease and motional
resistance increase.
