Precautions For Use Over current proof Customer must apply resistors for protection, otherwise slight voltage shift will cause big current change Burn out will happen Storage 1. The operation of temperature and R.H. are -20 80, 60 R.H. Max.. 2. Once the package is opened, the products should be used within a week. Otherwise, they should be kept in a dampproof box with desiccating agent. Considering the tape life, we suggest our customers to use our products within 1.5 year from production date. It is recommended to bake before soldering when the package is unsealed after 72 hrs. The condition is : 60 ±5 for 15hrs.
