Feed hole position  

Joint  

The products are placed in cavities of a carrier tape and sealed by a cover tape (top tape and bottom  

tape when the cavities of the carrier tape are punched type).  

The feed holes on the carrier tape are on the right side when the cover tape (top tape when the  

cavities of the carrier tape are punched type) is pulled toward the user.  

The carrier tape and cover tape (top tape when the cavities of the carrier tape are punched type) are  

seamless.

12.9 Storage and transportation  

Storage period  

Use the product within 6 months after delivery.  

If you do not use the product for more than 6 months, check solderability before using it.  

Storage conditions

 

• The products shall be stored in a room not subject to rapid changes in temperature and  

humidity. The recommended temperature range is -10°C to +40°C. The recommended relative  

humidity range is 15% to 85%.  

Keeping the product in corrosive gases, such as sulfur, chlorine gas or acid may cause the  

poor solderability.  

• Do not place the products directly on the floor; they should be placed on a palette so that they  

are not affected by humidity or dust.  

• Avoid keeping the products in a place exposed to direct sunlight, heat or vibration.  

• Do not keep products in bulk packaging. Bulk storage could result in collisions between the  

products or between the products and other parts, resulting in chipping or wire breakage.  

• Avoid storing the product by itself bare (i.e. exposed directly to air).  

Transportation  

Excessive vibration and impact reduces the reliability of the products. Exercise caution when  

handling the products.  

12.10 Resin coating (including moisture-proof coating)  

When the product is coated/molded with resin, its electrical characteristics may change.  

A wire breakage issue may occur by mechanical stress caused by the resin, amount/cured shape of resin, or operating  

condition etc.  

Some resins contain impurities or hydrolyzable chlorine, which could result in corrosion of the conducting materials, leading  

to wire breakage.  

So, please pay your careful attention when you select resin in case of coating/molding the products with the resin.  

Prior to use the coating resin, please make sure no reliability issue is observed by evaluating products mounted on your  

board.  

12.11 Mounting conditions  

Check the mounting condition before using.  

Using mounting conditions (nozzles, equipment conditions, etc.) that are not suitable for products may lead to pick up errors,  

misalignment, or damage to the product.  

12.12 Operating environment  

Do not use this product under the following environmental conditions as it may cause deterioration of product quality.  

(1) In the corrodible atmosphere such as acidic gases, alkaline gases, chlorine, sulfur gases, organic gases and etc.  

(the sea breeze, Cl2, H2S, NH3, SO2, NO2, etc)  

(2) In the atmosphere where liquid such as organic solvent, may splash on the products.  

(3) In the atmosphere where the temperature/humidity changes rapidly and it is easy to dew.  

12.13 Mounting density  

If this product is placed near heat-generating products, be sure to implement sufficient heat-dissipating measures.  

If this product is subjected to a significant amount of heat from other products, this could adversely affect product quality,  

resulting in a circuit malfunction or failure of the mounted section. Also, be sure that the product is used in a manner so that  

the heat that the product is subjected to from other products does not exceed the upper limit of the rated operating  

temperature for the product.
