DESCRIPTION

SQXO2ATHG oscillators are miniature oscillators produced in the

space-efficient and ultra-reliable TO-39 package. The oscillator is

designed for extended high temperature operation <200°C. The part

has excellent calibration and stability over a wide temperature range

and has excellent shock resistance.
