CX18SM CRYSTAL 30 MHz to 50 MHz Ultra-Miniature Surface Mount Quartz Crystal DESCRIPTION TM glass lid PACKAGE DIMENSIONS AR Y When miniaturization is paramount, Statek’s ultra-miniature CX18SM quartz crystal is the most ideal choice. This crystal is available in frequencies from 30 MHz to 50 MHz, and has typical overall dimensions of 1.55 mm x 0.95 mm x 0.35 mm. This surface mount crystal is hermetically sealed within an ultra-miniature package to ensure high stability and low aging. The extremely small size of this crystal makes the CX18SM ideally suited for many high frequency applications.
