CX-1H-03 CRYSTAL 10 kHz to 600 kHz Miniature Quartz Crystal for Series Oscillators ™ DESCRIPTION The CX-1H quartz crystal is a high quality tuning fork resonator for use in Series (two cascaded inverters) oscillators. The CX-1H is hermetically sealed in a rugged, miniature ceramic package, one-fourth the size of an eight-pin mini-DIP. The CX-1H 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 PACKAGE DIMENSIONS FEATURES Miniature tuning fork design F E High shock resistance Designed for low power applications Compatible with hybrid or PC board packaging D A Low aging Full military testing available Designed and manufactured in the USA B C PACKAGE HANDLING TYP. 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 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. MAX.
