CX-1-03 Datasheet, PDF (1/2 Pages) STATEK CORPORATION – Miniature AT-Cut Quartz Crystal

™
DESCRIPTION
The CX-1 quartz crystal is a high quality miniature AT cut
quality resonator. The CX-1 is hermetically sealed in a
rugged, miniature ceramic package, one-fourth the size of an
eight-pin mini-DIP. The CX-1 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^oC, glass lid to package seal rim
temperature should not exceed 210^oC. 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.
