7. 贮存方法 Storage Methods
7.1
存储期限 Storage Period
Page 4 of 5
为保证端子电极的焊接特性和包装材料处于良好状态,请于本公司发货后 6 个月内使
用本产品。同时,由于端子电极的焊接特性会随时间发生变化,如果贮存时间超过 6 个月,
请首先确认其焊接特性后再安装使用。
To maintain the solderability of terminal electrodes and to keep the packing material
in good condition, product should be used within 6 months from the time of delivery. And
the solderability of products electrodes may decrease as time passes, so in case of
storage over 6 months, solderability shall be checked before actual usage.
7.2
存储条件 Storage Conditions
⑴存放货物的仓库应满足以下条件 Store products in a warehouse in compliance with the
following condition:
温度(Temperature): -5 ~ +35℃
相对湿度(Humidity): 30~70%RH
⑵不要使产品遭受温度和湿度的快速变化。
Do not subject products to rapid changes in temperature and humidity.
⑶不要将产品存放在化学环境中,如硫酸气体或碱性气体中,否则会降低电极端子的焊接
特性和使电感器腐蚀。
Do not store the products in chemical atmosphere such as one containing sulfurous
acid gas or alkaline gas, that will causes poor solderability and corrosion of inductors.
⑷为了避免受潮气、灰尘等物质的影响,产品应保管于货架上。
Store products on pallets to protect from humidity, dust, etc
⑸产品应避免热冲击、振动以及直接光照等等。
Avoid heat shock, vibration, direct sunlight, etc.
