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

All the specifications are subject to change without previous notice.
