CX3HSM CRYSTAL
18 kHz to 600 kHz
Low Profile Surface Mount
Quartz Crystal for Series Oscillators
DESCRIPTION
The CX3HSM 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 Series oscillators. They are
hermetically sealed in a rugged, miniature ceramic
package. They are manufactured using the STATEK-
developed 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 260
