Storage Conditions

The guaranteed period for solderability is 6 months (Under deliver package condition).
Storage Conditions: Temperature 5~40¡æ       Relative Humidity: 20~70%


Precautions for Use
The Multilayer Ceramic Capacitors (MLCC) may fail in a short circuit modern in an open circuit mode when subjected to severe conditions of electrical environment and / or mechanical stress beyond the specified ¡°rating¡± and specified ¡°conditions¡± in the specification, which will result in burn out, flaming or glowing in the worst case. Following ¡°precautions for ¡°safety¡± and Application Notes shall be taken in your major consideration.

Soldering
To avoid the crack problem by sudden temperature change, follow the temperature profile in the adjacent graph (refer to the following graph).
Manual soldering can pose a great risk of creating thermal cracks in capacitors. The hot soldering iron tip comes into direct contact with the end terminations, and operator¡¯s careless may cause the tip of the soldering iron to come into direct contact with the ceramic body of the capacitor. Therefore the soldering iron must be handled carefully, and pay much attention to the selection of the soldering iron tip and temperature contact of the tip.

Solder deposition
Too much solder Cracks tend to occur due to large stress
Not enough solder Weak holding force may cause bad
connection between the capacitor and PCB.
