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.
