Packaging and Storage
Packaging
JK30-050～JK30-250 1000Pcs/Bag or 2000Pcs/Box
JK30-300～JK30-500 500 Pcs/Bag
JK30-600～JK30-900 200 Pcs/Bag
Storage
The maximum ambient temperature shall not exceed 40℃.Storage temperatures higher than 40℃ could result in the deformation of packaging materials.The maximum relative humidity recommended for storage is 70%.High humidity with high temperature can accelerate the oxidation the oxidation of the solder plating on the termination and reduce the solderability of the components.sealed plastic bags with desiccant shall be used to teduce the oxidation of the termination and shall only be opened prior to use.the products shall not be stored in areas where harmful gases containing sulfu of chlorine are present.
Warning:
Please read this specification before use the product.
Using of this product must be sure to follow the requirement of this specification,operation beyond the specified maximum ratings or improper use may result in damage and possible electrical arcing and flame.
PPTC resettable fuses are intended for occasional over current protection. Application for repeated over current condition or prolonged trip are not anticipated.
Please avoid contact of PPTC resettable fuses with chemical solvent. Prolonged contact will damage the device performance. You are requested not to use our product deviating from the agreed specifications.
