Always consider safety when designing equipment and circuit. Plan for worst-case failure modes
such as short circuits and open circuits which might occur during use.
Install the following systems for a failsafe design to ensure safety if these products are to be used in
equipment where a defect in these products may cause the loss of human life or other signification damage,
such as damage to vehicles (automobile, train, vessel), traffic lights, medical equipment, aerospace
equipment, electric heating appliances, combustion/gas equipment, rotating equipment, and disaster/crime
prevention equipment.
Products should be stored in a moisture proof environment. Storage conditions before and after opening the
moisture proof packaging as follows.
(If these conditions are exceeded, the package may absorb moisture and there is a risk of damage to the
exterior due to heat stress during mounting.)
[Environment of storage]
Products should be all used within the storage term after opening the package.
After the storage limit, baking treatment is necessary to be able to use the products.
The storage conditions after baking are the same as those after opening the package.
[Baking conditions]
Use at or under the rated (guaranteed) temperature.
Operation at temperatures exceeding specifications causes large changes in the capacitors electrical
properties, and deterioration than can potentially lead to failure.
When calculating the operating temperature of the capacitor, be sure to include not only the ambient
temperature and internal temperature of the unit, but also radiation from heat generating elements inside
the unit (power transistors, resistors, etc.), and self-heating due to ripple current.

(1) The system is equipped with a protection circuit and protection device.
(2) The system is equipped with a redundant circuit or other system to prevent an unsafe status in the event
Temperature: 5°C to 30°C without direct sunlight
Humidity: Less than 70%
Maximum storage term before opening the package: JEDEC J-STD-020C MSL: Level 2
Maximum storage condition after opening the package: JEDEC J-STD-020C MSL: Level 3
Temperature: 50±2°C
Time: 100h to 200h(Do not perform more than twice.)
Refer to the land size described next page for appropriate design dimensions. Circuit board design requires
examination of the most suitable dimensions taking conditions such as circuit board, parts and re-flow into
consideration.
These products are designed specifically for re-flow soldering. Consult with our factory before performing
mounting processes other than re-flow soldering.
