Be sure to have a mounting test in advance by using the actual mounting machine and check that the characteristics of the products are not damaged by the automatic mounting. In the process where the boad is warped, such as board separation process, be careful that the warping does not influence the characteristics and soldering of crystal products. Since mounting by Ultrasonic welding and processing have a possibility of an excessive vibration spreading inside a crystal resonator and becoming the cause of characteristic deterioration and not oscillating, it does not recommend. 3.WASHING About use of the washing liquid of a basin system, an alcoholic system, and a chlorofluorocarbon-replacing material system, it is checking that it is satisfactory. However please consult in advance about other washing liquid. Although the check about ultrasonic washing is performed, since it is an examination with a simple substance, the check for the second time by the use state is recommended. 4.THE CAUTIONS ON USE The piece of crystal it is processed very smaller than the conventional thing inside DSX321G series crystal unit may be damaged, if excessive excitation electric power is applied. Please use it below with the value specified on a catalog and specifications. Please refrain from forming patterns under crystal resonators since there is a possibility to cause crack in base. If the temperature is higher than 280 [deg.C], there is a possibility for the sealing glass to remelt. Avoid using the product at temperature higher than specified. 5.HANDLING OF A PRODUCT DSX321G series has sufficient intensity to fall and vibration. However when too much shock is added according to a certain cause, the use after a characteristic check is recommended. 6.STORAGE Since the soldering nature of a terminal may be degraded, please avoid storage in high temperature and a humid place. Please keep it in the place which direct rays do not hit and dew condensation does not generate. TITLE DSX321G TYPE SURFACE MOUNT TYPE QUARTZ CRYSTAL SPECIFICATION Date 2008/01/23 Remark Spec.
