CX6SM AT CRYSTAL
9.6 MHz to 250 MHz
Ultra-Low Profile Miniature
Surface Mount AT Quartz Crystal
DESCRIPTION
STATEK’s miniature CX6SM AT crystals in leadless ceramic
packages are designed for surface mounting on printed circuit
boards or hybrid substrates. These crystals have a small land
pattern and a low profile. 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.
