The NX1612AA low profile high reliability surface mount crystal measures only 1.6 mm L × 1.2 mm W × 0.3 mm H, taking only 40% of the volume and 60% of the board space of the company's previous generation crystal products. These devices operate in a fundamental frequency range of 26~80 MHz. Frequency tolerance at 25°C is ±10 ppm and their frequency stability vs. temperature is: ±10 ppm over -20 to 70°C. The NX1612AA exhibits a maximum series ESR (equivalent series resistance) of 200? in the frequency range of 26~36 MHz and 100? in the 36~80 MHz frequency range. The standard load capacitance is 7 pF, however other values can be made available. The NX1612AA is presented in a lead-free, RoHS conformance package and meets the re-flow profiling requirements for lead-free solder.
