Polymer Positive Temperature Coefficient as know as PPTC
Resettable fuses are designed and made of patented novel polymeric PTC material in thin chip form, developed solely by. With electrodes and leads attached on both sides, it is placed in series to protect a circuit. At “normal operating condition” the device remains at an extremely low resistance (milli-ohms) and allows the electrical current to flow through it without any restriction. When overcurrent conditions occur, the polymeric PTC material heats up and its resistance increases sharply. Such a sharp resistance increase (to an insulated status) cuts off the current in the circuit, and consequently protects the element and device in the circuit. Upon fault current being removed, the resettable fuse cools down and its resistance drops to the original extremely low value. The resettable fuse is “reset” and allows the current flow through the circuit again.
These expertises of polymeric PTC material and product engineering, grants us the flexibility and advantage on new product development. With our own patented PPTC formula, we can custom the product electrical characteristics to meet customer specific requirements and design PPTC device structure for special application.engineering expertise altogether, is your solutionprovider for circuit protection.
