“XH42” Series, 7 x 9 mm
High Temperature Hybrid Microcircuit Crystal Oscillators
( 1.8 VDC, 2.5 VDC, 3.3 VDC 5.0 VDC
500 KHz to 40 MHz )
Description
Xsis Electronics “XH42” Series High Temperature
crystal oscillators are designed and processed to
operate over an extended temperature range of
-55
o
C to 230
o
C. These oscillators are offered in a
low profile, hermetically sealed resistance welded
7x9 mm ceramic package.
High temperature materials and proven processes are
utilized to provide high reliability and long life at
extreme temperatures.
In addition, the quartz crystal is mounted at four
points to provide excellent shock and vibration
resistance.
