CX18SM CRYSTAL - Statek Corporation

CX18SM CRYSTAL
30 MHz to 50 MHz
Ultra-Miniature
Surface Mount Quartz Crystal
DESCRIPTION
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.
