High-voltage surface-mounted PPTC resettable fuse with novel architecture

The invention provides a high-voltage surface-mounted PPTC resettable fuse with a novel framework. The high-voltage surface-mounted PPTC resettable fuse comprises a high-voltage PPTC chip, a PCB, a first conductive film and insulating layers, an inner hole is formed in the middle of the PCB, semicircular notches are formed in the two ends of the PCB respectively, the high-voltage PPTC chip is embedded into the inner hole to jointly form an embedded chip board, the upper outer surface and the lower outer surface of the embedded chip board are covered with the insulating layers respectively, a conductive film is arranged on the outer surface of the insulating layer, a first fracture notch is etched in the position, close to the semicircular notch and perpendicular to the two side lines, of the first conductive film on the upper outer surface of the embedded chip board, and a second fracture notch is etched in the position, close to the semicircular notch and perpendicular to the two side lines, of the first con
