※）The saturation current value (Idc1) is the DC current value having inductance decrease down to 30%. (at 20℃)
※）The temperature rise current value (Idc2) is the DC current value having temperature increase by 40℃. (at 20℃)
※）The rated current value is following either Idc1 or Idc2, which is the lower one.

7. Storage conditions
Precautions
Technical
considerations
◆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 : 0～40℃
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.
◆Storage
1. The ambient of high temperature or high humidity might accelerate to make the solderability and the tape worse.
