avoid damp places and/or dusty places.

2.3.3 Please do not store the products in the places such as: in a damp heated place,

in a place where direct sunlight comes in, in place applying vibrations.

2.3.4 Please use the products immediately after the package is opened, because

the characteristics may be reduced in quality, and/or be degraded in the solderability
due to storage under the poor condition.

F

2.3.5 Please do not drop the products to avoid cracking of ceramic element.

2.4 Please be sure to consult with our sales representative or engineer whenever and

prior to using the products.

2.5 The component may be damaged if mechanical stress over this specification is applied.
