5. STORAGE

5.1 The solderability of the external electrode may be deteriorated if packages are stored where they

are exposed to high humidity. Packages must be stored at 40℃ or less and 70﹪RH or less.

5.2 The solderability of the external electrode may be deteriorated if packages are stored where they

are exposed to dust or harmful gas (hydrogen chloride,sulfurous acid gas or hydrogen sulfide).

5.3 Packaging material may be deformed if packages are stored where they are exposed to heat or

direct

sun－light.
