RSG CX3VCSM3

CX3VSM CRYSTAL
18 kHz to 600 kHz
Miniature Surface Mount
Quartz Crystal for Pierce Oscillators
™
DESCRIPTION
actual size
The CX3VSM 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 Pierce oscillators. They are
hermetically sealed in a rugged, miniature ceramic
package. They are manufactured using the STATEKdeveloped photolithographic process, and were
designed utilizing the experience acquired by producing
millions of crystals for industrial, commercial, military and
medical applications. Maximum process temperature
should not exceed 260O C.
