The EQXO-75UIE series is a ruggedized high-reliability, high temperature range clock oscillator in a standard format 7x5mm SMD ceramic package designed for demanding and vibrating industrial applications

Saelig Company, Inc. has launched the Euroquartz EQXO-75UIE Extended Industrial Temperature Ruggedized High-Reliability Oscillators. The EQXO-75UIE series is a ruggedized high-reliability SMD clock oscillator. Designed for demanding industrial applications, it provides reliable operation with excellent frequency stability across an extended industrial operating temp range of -40degC to +105degC. Mechanical shock survivability has been tested to 1500G MIL-STD-883K Meth 2002.5, Condition B.
Temperature stabilities of ±50, 75 & 100ppm are available, with tighter options by request (dependent on conditions). This component, available with short lead time, has no ITAR restrictions. All EQXO-75UIE crystals are pre-aged as part of an additional manufacturing process in order to improve long-term application stability. With an aging specification of ±1ppm maximum for the first year, an even tighter aging specification is available by request.
