CX-1-03-LF

CX-1-03 CRYSTAL 8 MHz to 160 MHz Miniature AT -Cut Quartz Crystal ™ Fundamental Mode: 8 MHz - 70 MHz Third Overtone Mode: 48 MHz - 160 MHz 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. actual size side view FEATURES PACKAGE DIMENSIONS Low-profile hermetically-sealed package Excellent aging characteristics Fundamental or 3rd overtone mode High shock resistance Full military testing available Designed and manufactured in the USA B A E F D PACKAGE HANDLING C TYP.

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 resulting in degradation of crystal performance. Mishandling of CX crystals can cause cracking of the glass lid and loss of hermeticity. DIM A B C D E F INCHES .315 .140 .070 .300 .020 .150 Leads 0.013” x 0.018” (0.33 x 0.46 mm) typical.

The crystal oscillates at a frequency fO above the crystal’s series-resonant frequency fs. The crystal is effectively inductive and, in combination with RA, Cd and Cg in the feedback loop, provides approximately 180O phase shift necessary to obtain oscillation.
