　　Stacked self-healing fuse

　　Stacked self-healing fuse is an innovative circuit protection component that provides efficient and reliable circuit protection solutions for electronic devices and circuit systems with its unique structural design and excellent performance characteristics. This type of fuse is like a sturdy shield, always guarding the safety of the circuit and ensuring stable operation of the equipment in various complex environments.

　　The structure of a laminated self-healing fuse is similar to stacking multiple layers of thin films together. It is composed of a polymer matrix and conductive particles inside, which are evenly distributed in the polymer matrix and form a conductive pathway. Under normal working conditions, the contact between conductive particles is good, and the resistance value of the fuse is very low, which almost does not affect the normal operation of the circuit. However, when an overcurrent fault occurs in the circuit, the increase in current causes the temperature of the fuse to rise, the polymer matrix to expand due to heat, and the spacing between conductive particles to increase, resulting in a rapid increase in the resistance value of the fuse, limiting further increase in current and achieving protection of the circuit.

　　Stacked self-healing fuses have many advantages, making them widely applicable in the field of circuit protection. Firstly, it has self recovery characteristics, which can automatically restore to a low resistance state after troubleshooting, without the need for manual replacement of fuses, greatly improving the reliability and maintenance efficiency of the equipment. Secondly, it has a fast response speed and can respond to overcurrent faults in a short period of time, effectively protecting circuits and equipment from damage. In addition, the size and weight of laminated self-healing fuses are small and light, making them suitable for use in electronic devices with limited space. It also has high pressure resistance and environmental resistance, and can work stably in various harsh working environments.

　　In practical applications, laminated self-healing fuses are widely used in portable electronic devices such as smartphones, tablets, laptops, digital cameras, and wearable devices. It can effectively protect the battery charging circuit, power management circuit, audio circuit, video circuit, etc. of these devices, preventing damage to the equipment due to overcurrent, short circuit and other faults. In addition, laminated self-healing fuses have also been applied in fields such as automotive electronics, industrial control, and communication equipment.

　　In summary, laminated self recovery fuses have become an ideal circuit protection component in modern electronic devices and circuit systems due to their efficient and reliable circuit protection performance, self recovery characteristics, fast response speed, and compact size. It provides strong guarantees for the safe operation of various electronic devices and makes important contributions to the development of electronic technology.
