The resettable fuse is a heat-sensitive semiconductor material. The sensitivity itself is not high. If the sensitivity is not considered, it can be used. The main parameter of the fuse is the fusing current. As long as the withstand voltage exceeds the voltage in the actual circuit, it will be fine. For example, we often Glass tube fuses generally have a withstand voltage of 250VAC, but in actual application, it is the same whether it is AC or DC, whether it is 220V or 12V. What you need to consider is whether the fusing current is highly sensitive or needs to be broken quickly. The fuse is that the self-restoring fuse is a slow-blow type fuse. The material of the self-restoring fuse generates heat after being energized. When the current is too large and the heat reaches a certain level, the material will no longer conduct electricity. This is the same as ordinary fuses, except that Ordinary fuses only blow once. Resettable fuses are composed of specially treated polymer resin (Polymer) and conductive particles (Carbon Black) distributed inside. Under normal operation, the polymer resin tightly binds the conductive particles outside the crystal structure, forming a chain-like conductive path. At this time, the resettable fuse is in a low resistance state (a), and the current flowing through the resettable fuse on the line generates The heat energy is small and will not change the crystal structure. When a line is short-circuited or overloaded, the heat generated by the large current flowing through the resettable fuse melts the polymer resin, and the volume grows rapidly, forming a high-resistance state (b), and the operating current decreases rapidly, thereby limiting and protecting the circuit. When the fault is eliminated, the resettable fuse re-cools and crystallizes, shrinks in volume, and the conductive particles re-form a conductive path. The resettable fuse returns to a low-resistance state, thus completing the protection of the circuit without manual replacement.
Huaju Electronics is a professional manufacturer of resettable fuses. The company mainly engages in the R&D and production of thermistors, varistors, and resettable fuses. Relying on its strong R&D capabilities, the company has recently launched a low-power, low-resistance chip resettable fuse, which is suitable for battery-powered handheld devices and can effectively increase the use time of the device. It is another flagship product of the company.
