CX6VSM CRYSTAL
18 kHz to 600 kHz
Ultra-Low Profile (1mm) Miniature Surface Mount
Quartz Crystal for Pierce Oscillators
DESCRIPTION
The CX6VSM quartz crystals are leadless devices designed
for surface mounting on printed circuit boards or hybrid
substrates and 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 are designed
utilizing the experience acquired by producing millions of
crystals for industrial, commercial, military and medical
applications. Maximum process temperature should not
exceed 260OC.
