5x7mm 4-Point Mount Extreme High Shock Resistant Crystal Oscillator
1.8V, 2.5V, 3.3V, 5Vdc | 500kHz to 156.25MHz
Description
Q-Tech’s 5x7mm low profile extreme high shock
hybrid oscillators consist of an IC operating at various
supply voltages from 1.8V, 2.5V, 3.3V, and 5.0Vdc
and a miniature strip quartz crystal. The series is
offered in various ceramic package configurations
from true Surface-Mount SMT to straight leads and
formed leads. This is the smallest package offered
with a four-point crystal mount for high shock and
high reliability military applications.
