disaster prevention, medical, public information network (telephone exchange, base station) etc. which may have
direct influence to harm or injure a human body, please contact Taiyo Yuden Co., Ltd. for more detail in advance.
Do not incorporate the products into any equipment in fields such as aerospace, aviation, nuclear control, subma-
rine system, military, etc. where higher safety and reliability are especially required.
In addition, even electronic components or functional modules that are used for the general electronic equipment,
if the equipment or the electric circuit require high safety or reliability function or performances, a sufficient reliabil-
ity evaluation check for safety shall be performed before commercial shipment and moreover, due consideration to
install a protective circuit is strongly recommended at customer's design stage.

Precautions
◆Operationg Ambient
The products are premised on the usage for the general equipments like the office supply equipment, the telecommunications systems, the measuring
equipment, the household equipment and so on.
Please ask to TAIYO YUDEN's sales person in advance, if you need to apply them to the equipments or the systems which might have any influences for the
human body, the property, like the traffic systems, the safety equipment, the aerospace systems, the nuclear control systems, the medical equipment and so
on.
2. PCB Design
Precautions ◆Land pattern design
1. Please refer to a recommended land pattern.

Technical
consider-
ations
◆Adjustment of mounting machine
The products might be broken if too much stress is given for the picking and placing.
4. Soldering
Precautions
◆Reflow soldering
1. Please apply our recommended soldering conditions on the specification as much as possible.
2. The products are only for reflow soldering.
3. Please do not give any stress to a product until it returns in room temperature after reflow soldering.
◆Lead free soldering
1. Please check the adhesion, the solder temperature, the solderability and the shape of solder filet if the solder that is not in the specification is used.
◆Recommended conditions for using a soldering iron (NR10050 Type)
Touch a soldering iron to the land pattern not to the product directly.
The temperature of a soldering iron is less than 350degC.
The soldering is for 3 seconds or less.
Technical

7. Storage conditions
Precautions
◆Storage
1. The packing boxes can be kept at the ambient which the temperature is from 0 to 40degC and the humidity is less than 70%.
2. Tthe ambient temperature of less than 30degC is recommended not to get the tape and the solderability worse.
3. Please solder the products by a half year after they have been shipped.
Otherwise please use them after checking the solderability in advance.
