Warning: Please read this specification before use the product。 Using of this product must be sure to follow the requirement of this specification，operation beyond the specified maximum ratings or improper use may result in damage and possible electrical arcing and flame. PPTC resettable fuses are intended for occasional over current protection. Application for repeated over current condition or prolonged trip are not anticipated. Please avoid contact of PPTC resettable fuses with chemical solvent. Prolonged contact will damage the device performance. You are requested not to use our product deviating from the agreed specifications.
