■PRECAUTIONS
1. Circuit Design
Precautions
◆Operating environment
1. The products described in this specification are intended for use in general electronic equipment,(office supply equipment,
telecommunications systems, measuring equipment, and household equipment). They are not intended for use in mission-critical
equipment or systems requiring special quality and high reliability (traffic systems, safety equipment, aerospace systems, nuclear
control systems and medical equipment including life-support systems,) where product failure might result in loss of life, injury or
damage. For such uses, contact TAIYO YUDEN Sales Department in advance.
2. PCB Design
Precautions
Technical
considerations
◆Land pattern design
1. Please refer to a recommended land pattern.
◆Land pattern design
Surface Mounting
・ Mounting and soldering conditions should be checked beforehand.
・ Applicable soldering process to this products is reflow soldering only.
3. Considerations for automatic placement
Precautions
Technical
considerations
◆Adjustment of mounting machine
1. Excessive impact load should not be imposed on the products when mounting onto the PC boards.
2. Mounting and soldering conditions should be checked beforehand.
◆Adjustment of mounting machine
1. When installing products, care should be taken not to apply distortion stress as it may deform the products.
4. Soldering
Precautions
◆Reflow soldering
1. Please contact any of our offices for a reflow soldering, and refer to the recommended condition specified.
2. The product shall be used reflow soldering only.
3. Please do not add any stress to a product until it returns in normal temperature after reflow soldering.
◆Lead free soldering
1. When using products with lead free soldering, we request to use them after confirming adhesion, temperature of resistance to soldering
heat, soldering etc sufficiently.

2. There is a case to be broken by the handling in transportation.
◆Pick-up pressure
1. Damage and a characteristic can vary with an excessive shock or stress.
◆Packing
1. If packing boxes are accumulated, that could cause a deformation on packing tapes or a damage on the products.
◆Board mounting

2. If components which are located in peripheral of product make contact with surface (top, side) of product, it may cause damage or
characteristics change.
7. Storage conditions
Precautions
◆Storage
1. To maintain the solderability of terminal electrodes and to keep the packing material in good condition, temperature and humidity in the
storage area should be controlled.
・ Recommended conditions
Ambient temperature : －5～40℃
Humidity : Below 70% RH
・ The ambient temperature must be kept below 30℃. Even under ideal storage conditions, solderability of products electrodes may
decrease as time passes.
For this reason, product should be used within 6 months from the time of delivery.
In case of storage over 6 months, solderability shall be checked before actual usage.
Technical
considerations
◆Storage
1. Under a high temperature and humidity environment, problems such as reduced solderability caused by oxidation of terminal electrodes
and deterioration of taping/packaging materials may take place.
