Cautions for Handling a) Prevention against electrostatic breakdown Your full attention to static electricity is still requested. b) Direction Before mounting the crystal oscillator on board, Please confirm the direction to make sure the GND terminal and the terminal of power supply are not taken wrongly. 2. Prevention against Vibration and Shock While the product is being transported or mounted onto board, if undue hock and vibration exceeding the specification is put on, there is risk hat the built-in crystal blank is broken. When undue shock and vibration exceeding the specification is put on the product,please be sure to make confirmation of the product’s characteristics. 3. Soldering In order to assure the reliability of the crystal oscillator, please use the product under the recommended conditions. 4. Surface mounting a)This product is surface-mounting device. So, Please pay attention to the following things. b)Extreme deformation of board may make pattern off, the electrode of terminals off and solder broken.Full attention is requested especially when splitting the board with the oscillator mounted where the camber of the board occurs. c)In case that automatic mounter is used, please choose the type with small shock generation and make confirmation of the shock before use. 5. Cleaning Because cleaning will cause change to all characteristics, cleaning is forbidden. 6. Store keeping (method and duration) Long-time storage in the high/low temperature and high humidity leads to deterioration of solderability. So, please keep the product in the temperature of +5~+35 and humidity of 45~70%. Moreover, please keep the product in the circumstance with measures against static electricity. The storage life is 6 months before the pack is opened and please use it within 168 hours after the pack is opened. (Please keep it with desiccator etc. when you exceed 168 hours after the bag is opened. Please use it after confirming the product solderability.)
