| CX2HSM CRYSTAL 16 kHz to 600 kHz TM Miniature Surface Mount Quartz Crystal for Series Oscillators DESCRIPTION The CX2HSM 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 Series oscillators. They are hermetically sealed in a rugged, miniature ceramic package. The CX2HSM 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. Maximum process temperature should not exceed 260OC.
