Warning:
-Operation beyond the specified maximum ratings 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. Prolonged contact will damage the device
performance.
