CX6VSM

CX6VSM CRYSTAL 18 kHz to 600 kHz ™ Ultra-Low Profile (1mm) Miniature Surface Mount Quartz Crystal for Pierce Oscillators DESCRIPTION The CX6VSM quartz crystals are leadless devices designed for surface mounting on printed circuit boards or hybrid substrates and 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 are designed utilizing the experience acquired by producing millions of crystals for industrial, commercial, military and medical applications. Maximum process temperature should not exceed 260OC.
