WARNING ■ Mechanical Stress ·PPTC devices will undergo a thermal expansion during fault condition. If PPTC devices are installed or placed in an application where the space between PPTC devices and the surrounding materials (e.g., covering materials, packaging materials, encapsulate materials and the like) is insufficient, it will cause an inhibiting effect upon the thermal expansion. Pressing, twisting, bending and other kinds of mechanical stress will also adversely affect the performance of the PPTC devices, and shall not be used or applied. ■ Chemical Pollutants ·Silicone-based oils, oils, solvents, gels, electrolytes, fuels, acids, and the like will adversely affect the properties of PPTC devices, and shall not be used or applied. ■ Electronic and Thermal Effect ·PPTC devices are secondary protection devices and are used solely for sporadic, accidental over-current or over-temperature error condition, and shall NOT be used if or when constant or repeated fault conditions (such fault conditions may be caused by, among others, incorrect pin-connection of a connector) or over-extensive trip events may occur. ·PPTC devices are different from fuses and, when a fault condition occurs, will go into high-resistance state and do not open circuit, in which case the voltage at such PPTC devices may reach a hazardous level. ·Operation over the maximum rating or other forms of improper use may cause failure, arcing, flame and/or other damage to the PPTC devices. ·Conductive material contamination, such as metal particle, may induce shortage, flame or arcing. ·Due to the inductance, the operation circuits may generate a circuit voltage (Ldi/dt) above the rated voltage of PPTC devices, which shall not be used under such circumstances. ■ General ·Customers shall evaluate and test the properties of PPTC devices independently to verify and ensure that their individual applications will be met. ·The performance of PPTC devices will be adversely affected if they are improperly used under electronic, thermal and/or mechanical procedures and/or conditions non-conformant to those recommended by manufacturer. ·Customers shall be responsible for determining whether it is necessary to have back-up, failsafe and/or fool-proof protection To avoid or minimize damage that may result from extra-ordinary, irregular function or failure of PPTC devices. ·Any and all responsibilities and liabilities are disclaimed if any item under this notice of warning is not complied with.

Soldering time The soldering time should be kept within 3 seconds, otherwise it might cause insulation layer cracking, and increased part resistance. Soldering position The distance on the leads between the soldering point and bottom of the PPTC body should be equal or greater than 4mm. Other The soldering iron should not contact the PPTC body except the leads. If the soldering conditions are kept to lower temperature, less time and larger distance, the outcome of the soldering will be better. Notes: 1. Before using the device must be stored in the original bags, if the storage conditions do not guarantee, the device may not be able to meet the given value. 2. The devices can’t used for reflow soldering.
