DESCRIPTION
STATEK’s ultra-miniature, low profile CX-7-SM AT-cut crystals
in leadless ceramic packages are designed for surface
mounting on printed circuit boards or hybrid circuits. These
crystals are low profile and have a very small land pattern.
Maximum process temperature should not exceed 260OC.
PACKAGE DIMENSIONS
