CHIP RESISTOR
本产品在以下特殊环境下应用，性能可能会受到影响：
1、在各种类型的液体，包括水、油、化学品、有机溶剂的使用。
2、在户外直接暴露在阳光的地方，或在灰尘多的地方使用。
3、在产品暴露的地方，有海风或腐蚀性气体，包括氯气 、硫化氢、氨气、二氧化硫、二氧化氮等。
4、在产品暴露于静电或电磁波的地方使用。
5、在产生热量的部件、塑料线，或其他易燃物品附近使用。
6、在用树脂或其他涂层材料密封产品的情况下使用。
7、焊接后使用不洁焊料或使用水或水溶性清洗剂清洗产品。
8、片状电阻器的基材是氧化铝。由于和安装基板的热膨胀系数不同，在反复施加提供热循环等热应力时，接合部的
焊锡（焊缝部）有时会发生裂纹。如果环境温度反复发生很大的变动，并且载荷反复进行ON/OFF，则需要注意龟
裂的发生。因热应力而发生的龟裂，取决于所安装的焊盘的大小、焊锡量、安装基板的散热性等，因此在环境温
度有很大的变化或载荷ON/OFF的条件下使用时，请充分注意以进行设计。

、Use in places where the products are exposed to static electricity or electromagnetic waves.
、Use in proximity to heat-producing components, plastic cords, or other flammable items.
、Use involving sealing or coating the products with resin or other coating materials.
、Use involving unclean solder or use of water or water-soluble cleaning agents for cleaning after soldering.
、The substrate of chip resistors is alumina. Cracks may occur at the connection of solder (solder fillet
portion) due to the difference of the coefficient of thermal expansion from a mounting board when heat
stress like heat cycle, etc. are repeatedly given to them. Care should be taken to the occurrence of the
cracks when the change in ambient temperature or ON/OFF of load is repeated. The occurrence of the
crack by heat stress may be influenced by the size of a pad, solder volume, heat radiation of mounting
board etc., so please pay careful attention to designing when a big change in ambient temperature and
conditions for use like ON/OFF of load can be assumed.
