Cautionary Notes:
Each product should be carefully evaluated and tested for their suitability
of application.
1.Operation beyond the specified maximum rating or improper use may
result in damage and possible electrical arcing and/or flame.
2.PPTC device are intended for occasional overcurrent protection.
Application for repeated overcurrent condition and/or prolonged trip are
not anticipated.
3.Avoid contact of PPTC device with chemical solvent, including some
inert material such as silicone based oil, lubricant and etc. Prolonged
contact will damage the device performance.
4.Additional protection mechanism are strongly recommended to be
used in conjunction with the PPTC device for protection against
abnormal or failure conditions.
