Case must not exceed 150°C With regard to wave soldering it is recommended that the process is carried out with the crystal unit set upright on the circuit board. Should the process be carried out with the crystal unit on its side then steps must be taken to prevent heat transfer through the can. Should the whole crystal unit be heated (in a re-flow oven for example) it will result in amarked deterioration of the performance or even failure to oscillate. This is due to the internal construction of the crystal unit which involves the use of solder. Please note that all parameters can not necessarily be specified in the same device Customer to Specify : Frequency, Frequency Tolerance, Operating Temperature Range & Load Capacitance In line with our ongoing policy of product evolvement and improvement, the above specification may be subject to change without notice.

As each of these specification parameters impact on each other, it is not always possible to combine all options in one device. Therefore, if a specification not catered for above is required, please contact us directly for the relevant part number code(s). 2) ACT are always happy to consider truly custom specification parts which may require non-standard specification parameters, specific testing, customer requested AQL requirements, non standard packaging or taping and reeling and custom marking.
