DESCRIPTION
The CX-1V-SM quartz crystal is a high quality tuning fork
resonator for use in Pierce (single inverter) oscillators. The
CX-1V-SM is hermetically sealed in a rugged, miniature
ceramic package. The CX-1V-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
Designed for low power applications
Compatible with hybrid or PC board packaging
Low aging
Full military testing available
Ideal for battery operated applications
Designed and manufactured in the USA
