For example, many electronic semiconductors and passive devices, such as SMD resistors, SMD capacitors, fuses, inductors, etc., need to be packaged because the packaged products are more convenient to use. So is the fuse. After packaging, the fuse not only plays the role of placing, fixing and sealing, but also plays the role of fuse and enhancing heat conduction, which is not easy to be damaged. Convenient transportation. So how important the package is to the fuse, I will explain it in depth with the "effect" of self-healing fuse.
Self-healing fuse "effect"
Because the fuse must be isolated from the outside world, prevent impurities in the air from corroding the fuse circuit, resulting in deterioration of electrical functions, and maintain the fuse surface and connecting wires, so that the very delicate fuse can be protected from external forces and environmental factors at the electrical equipment or thermophysical level. To reduce the in-situ stress caused by thermal and other environmental factors and its negative impact on fuse burns, so as to prevent the fuse from being damaged and ineffective. On the other hand, as I said at the beginning, the fuse can be placed, fixed and sealed after packaging.
Generally speaking, we do not recommend secondary packaging of fuse products. If secondary packaging is necessary, we should pay attention to the selection of packaging materials. If the packaging material is too hard, it will lead to the normal use of the self-healing fuse, and even if the packaging material is soft, it may also lead to the heat dissipation and other functions of the self-healing fuse. Original packaging is recommended.
