: Some specifications are package dependent. Please refer to the spec. sheet of individual packages once a package is selected..
: TCXO products ordered without mechanical and electrical frequency tuning should have a frequency tolerance of ±2 ppm (at +25°C) and the frequency stability over temperature will be from that measured value.
