EURO QUARTZ CX-1-03 AT CRYSTAL Miniature AT-Cut Quartz Crystal 8MHz to 160MHz FEATURES Low profile, hermetically sealed ceramic package Excellent ageing characteristics High shock resistance Full military testing available Available with glass or ceramic lid Custom designs available OUTLINE & DIMENSIONS DESCRIPTION CX-1-03 AT crystals are designed in a rugged, ceramic package. Due to its robust design this crystal has gained wide acceptance in the industry. SPECIFICATION Specifications stated are typical at 25°C unless otherwise indicated. Specifications may change without notice.

Tighter tolerances available. 2. Does not include calibration tolerance. 3. Higher shock version 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 may damage the crystals. Lead to package solder interface temperature should not exceed 175°C, glass lid to package seal rim temperature should not exceed 210°C. 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.
