Warning: - Each product should be carefully evaluated and tested for their suitability of application.

- Operation beyond the specified maximum rating or improper use may result in damage and possible electrical arcing and/or flame.

- PPTC device are intended for occasional overcurrent protection. Application for repeated overcurrent condition and/or prolonged

trip are not anticipated.

- 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.

- Additional protection mechanism are strongly recommended to be used in conjunction with the PPTC device for protection against

abnormal or failure conditions.

- Avoid use of PPTC device in a constrained space such as potting material, housing and containers where have limited space to

accommodate device thermal expansion and/or contraction.
