Damage and a characteristic can vary with an excessive shock or stress. ◆Packing 1. If packing boxes are accumulated, that could cause a deformation on packing tapes or a damage on the products. 7. Storage conditions ◆Storage 1. To maintain the solderability of terminal electrodes and to keep the packing material in good condition, temperature and humidity in the storage area should be controlled. ・ Recommended conditions Ambient temperature : 0～40℃ Precautions Humidity : Below 70% RH ・ The ambient temperature must be kept below 30℃. Even under ideal storage conditions, solderability of products electrodes may decrease as time passes. For this reason, product should be used within 6 months from the time of delivery. In case of storage over 6 months, solderability shall be checked before actual usage. ◆Storage Technical 1. Under a high temperature and humidity environment, problems such as reduced solderability caused by oxidation of terminal electrodes considerations and deterioration of taping/packaging materials may take place. ▶ This catalog contains the typical specification only due to the limitation of space.
