CX1VSM

CX1VSM CRYSTAL 10 kHz to 600 kHz ™ Miniature Surface Mount Quartz Crystal for Pierce Oscillators DESCRIPTION The CX1VSM quartz crystal is a high quality tuning fork resonator for use in Pierce (single inverter) oscillators. The CX1VSM is hermetically sealed in a rugged, miniature ceramic package. The CX1VSM 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.
