Precautions For Use

1. Over-current-proof

Customer must apply resistors for protection, other-

wise slight voltage shift will cause big current change

(Burn out will happen).

2. Storage

2.1 Storage temperature and rel. humidity conditions

are: 5 °C to 30 °C, R.H. 60 %

2.2 Floor life must not exceed 72 h, acc. to JEDEC

level 4, J-STD-020.

Once the package is opened, the products should be

used within 72 h. Otherwise, they should be kept in a

damp proof box with desiccant.

Considering tape life, we suggest to use products

within one year from production date.

2.3 If opened more than 72 h in an atmosphere 5 °C

to 30 °C, R.H. 60 %, devices should be treated at

60 °C ± 5 °C for 15 hrs.

2.4 If humidity indicator in the package shows pink

color (normal blue), then devices should be treated

with the same conditions as 2.3
