◙ 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.

◙ Recommended soldering conditions
The lead-free termination MLCCs are not only to be used on SMT against lead-free solder paste, but also suitable
against lead-containing solder paste. If the optimized solder joint is requested, increasing soldering time, temperature and
concentration of N2 within oven are recommended.
