CX1V CRYSTAL 10 kHz to 600 kHz Miniature Quartz Crystal for Pierce Oscillators DESCRIPTION The CX1V quartz crystal is a high-quality tuning fork resonator for use in Pierce (single inverter) oscillators. The CX1V is hermetically sealed in a rugged, miniature ceramic package, one-fourth the size of an eight-pin mini-DIP. The CX1V 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 actual size side view Glass Lid Shown PACKAGE DIMENSIONS 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 Ideal for battery operated applications B Designed and manufactured in the USA 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.
