| CX2VSM CRYSTAL 16 kHz to 600 kHz TM Miniature Surface Mount Quartz Crystal for Pierce Oscillators DESCRIPTION actual size The CX2VSM 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.
