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 reduce 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 sulfur of
chlorine are present.
Warning
• Please read this specification before using the product.
• Use PPTC beyond the maximum ratings or improper use may result in device damage, electrical arcing and flame.
• PPTC are intended for protection against occasional over current or over temperature fault conditions and should not be
used when repeated fault conditions or prolonged trip events are anticipated.
• Device performance can be impacted negatively if devices are handled in a manner inconsistent with recommended
electronic, thermal, and mechanical procedures for electronic components.
• Use PPTC with a large inductance in circuit will generate a circuit voltage above the rated voltage of the PPTC.
• Avoid impact PPTC device its thermal expansion like placed under pressure or installed in limited space.
• Contamination of the PPTC material with certain silicon based oils or some aggressive solvents can adversely impact the
performance of the devices. PPTC can be cleaned by standard methods.
• Requests that customers comply with our recommended solder pad layouts and recommended reflow profile. Improper
board layouts or reflow profile could negatively impact solderability performance of our devices.
