CX-1HG-SM CRYSTAL
8 MHz to 160 MHz
TM
High Shock Miniature AT
-Cut Surface Mount Crystal
Fundamental Mode: 8 MHz - 70 MHz
Third Overtone Mode: 48 MHz - 160 MHz
DESCRIPTION
STATEK’s miniature CX-1HG-SM AT-cut crystals in
leadless ceramic packages are designed for surface
mount on printed circuit boards or hybrid circuits. These
crystals are designed for applications requiring exceptional
shock and vibration survival. Maximum process temperature
should not exceed 260
O
C.
