RSG CX2HSCSM3 Miniature surface mount quartz crystal for series oscillator Datasheet

CX2HSM CRYSTAL
16 kHz to 600 kHz
Miniature Surface Mount
Quartz Crystal for Series Oscillators
™
DESCRIPTION
The CX2HSM 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. The CX2HSM crystal
is manufactured using the STATEK-developed
photolithographic process, and was designed utilizing the
experience acquired by producing millions of crystals for
industrial, commercial, military and medical applications.
Maximum process temperature should not exceed 260OC.
