PRECAUTIONS FOR USE
1. Over-current-proof
Customer must apply resistors for protection, otherwise
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, RH 60
2.2. Floor life must not exceed 168 h, acc. to JEDEC level 3,
J-STD-020.
Once the package is opened, the products should be used
within 168 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 168 h in an atmosphere 5 °C to
30 °C, RH 60 %, devices should be treated at
60 °C ± 5 °C for 15 h.
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.
