DESCRIPTION
The CX-2H-SM 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 CX-2H-SM
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 260
O
C.
FEATURES
Miniature tuning fork design
High shock resistance
Compatible with hybrid or PC board packaging
Low aging
Full military testing available
Designed and manufactured in the USA
