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
