CX3VSM CRYSTAL 18 kHz to 600 kHz Miniature Surface Mount Quartz Crystal for Pierce Oscillators DESCRIPTION The CX3VSM quartz crystals are leadless devices designed for surface mounting on printed circuit boards or hybrid substrates. These miniature crystals are intended to be used in Pierce oscillators. They are hermetically sealed in a rugged, miniature ceramic package. They are manufactured using the STATEKdeveloped photolithographic process, and were designed utilizing the experience acquired by producing millions of crystals for industrial, commercial, military and medical applications. Maximum process temperature should not exceed 260O C. actual size side view Glass Lid Shown PACKAGE DIMENSIONS D TOP A BOTTOM E FEATURES D E B Miniature tuning fork design C High shock resistance TYP.
