DESCRIPTION
The CX-1H-SM quartz crystal is a high quality tuning fork
resonator for use in Series (two cascaded inverters)
oscillators. The CX-1H-SM is hermetically sealed in a
rugged, miniature ceramic package. The CX-1H-SM crystal
is manufactured using the STATEK-developed photo-
lithographic 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
Designed for low power applications
Compatible with hybrid or PC board packaging
Low aging
Full military testing available
Designed and manufactured in the USA
