EURO QUARTZ CX11LHG AT CRYSTAL High Shock, Ultra-Miniature SMD FEATURES 16MHz to 50MHz OUTLINE & DIMENSIONS Frequency Range 16MHz to 50MHz Mechanical shock survivability up to 75,000g Ultra-low profile and outline ceramic package Low acceleration sensitivity available Low ageing Full MIL testing available DESCRIPTION CX11LHG crystals are high performance devices designed to survive extreme shock and high vibration environments. Low acceleration sensitivity and low ageing performance are coupled with tight cailibration and temperature tolerances.
