* Devices can be cleaned using standard industry methods and solvents.
Notes:
If reflow temperatures exceed the recommended profile,
devices may not meet the performance requirements.

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 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 or chlorine are present.

Warning:

PPTC devices are intended for protection against occasional over-current or over-temperature fault conditions, and should not be used when repeated fault conditions are anticipated. Operation beyond maximum ratings or improper use may result in device damage and possible electrical arcing and flame.

Notes:

The specification is intended to present application, product and technical data toassist the user in selecting PPTC circuit pro

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 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 or chlorine are present.

Warning:

PPTC devices are intended for protection against occasional over-current or over-temperature fault conditions, and should not be used when repeated fault conditions are anticipated. Operation beyond maximum ratings or improper use may result in device damage and possible electrical arcing and flame.

Notes:

The specification is intended to present application, product and technical data to assist the user in selecting PPTC circuit

* Recommended reflow methods: IR, Vapor phase oven, hot air oven, wave solder.
* Devices can be cleaned using standard industry methods and solvents.
Notes:
If reflow temperatures exceed the recommended profile,
devices may not meet the performance requirements.

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 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 or chlorine are present.

Warning:

PPTC devices are intended for protection against occasional over-current or over-temperature fault conditions, and should not be used when repeated fault conditions are anticipated. Operation beyond maximum ratings or improper use may result in device damage and possible electrical arcing and flame.

Notes:The specification is intended to present application, product and technicaldata to assist the user in selecting PPTC circui
