| CX-2 CRYSTAL 9.6 MHz to 160 MHz TM Miniature AT -Cut Crystal Fundamental Mode: 9.6 MHz - 70 MHz Third Overtone Mode: 70 MHz - 160 MHz DESCRIPTION The CX-2 AT-cut quartz crystal is a high quality AT-cut resonator. The CX-2 is hermetically sealed in a rugged, miniature ceramic package, and available in several lead configurations. The CX-2 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. actual size FEATURES Low profile hermetically sealed ceramic package Excellent aging characteristics Available with glass or ceramic lid High shock and vibration resistance Custom designs available Full military testing available Designed and manufactured in the USA PACKAGE DIMENSIONS -02 End Lead .094 (2.39) -03 Side Lead .260 (6.60) .094 (2.39) 1 2 1 2 3 .260 (6.60) .210 (5.33) 3 .205 (5.21) .200 (5.08) A EQUIVALENT CIRCUIT A .050(1.27) C0 INCHES (mm) -04 Side Lead .260 (6.60) .094 (2.39) Notes: 1.Terminal 1 is electrically connected internally to terminal 3. 2.Lead dimensions Width: .013" (.33mm) Typical Thickness: .007" (.18mm) Typical 3.A = Glass Lid .080 (2.03) max.

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.
