NOTICE
（注意）
1． Do not use this product with bend. The component may be damaged if excess Mechanical stress is
applied to it mounted on the printed circuit board.（本产品不能折弯使用，在电路板安装时使用过
大的机械压力可能造成产品损坏。）
2．This specification limits the quality of the component as a single Unit Please make sure that the
component is evaluated and confirmed the drawing When it is mounted to your product.（本规格书只
规定了部件本身的品质，应用于您的产品时请确认图纸该产品是否适用。）
