DESCRIPTION

The CX-2V quartz crystal is a high quality tuning fork

resonator for use in Pierce (single inverter) oscillators. The

CX-2V is hermetically sealed in a rugged, miniature ceramic

package, one-fourth the size of an eight-pin mini-DIP. The

CX-2V 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

glass lid to package seal rim temperature should not

exceed 210

maximum specified, the package may lose its hermeticity. Loss

of hermeticity results in a frequency decrease and motional

resistance increase.
