◙ Storage and handling conditions

(1) To store products at 5 to 40

°C ambient temperature and 20 to 70%. related humidity conditions.

(2) The product is recommended to be used within one year after shipment. Check solderability in case of shelf life

extension is needed.

Cautions:

a. The corrosive gas reacts on the terminal electrodes of capacitors, and results in the poor solderability.

Do not store the capacitors in the ambience of corrosive gas (e.g., hydrogen sulfide, sulfur dioxide,

chlorine, ammonia gas etc.)

b. In corrosive atmosphere, solderability might be degraded, and silver migration might occur to cause low

reliability.

c.

Due to the dewing by rapid humidity change, or the photochemical change of the terminal electrode by

direct sunlight,the solderability and electrical performance may deteriorate. Do not store capacitors under

direct sunlight or dewing condition. To store products on the shelf and avoid exposure to moisture.
