　　There are two optional types of self recovery fuses and disposable fuses available for surface mounting. Both self recovery fuses and disposable fuses can respond to excessive current, but the "self recovery" device of self recovery fuses, based on polymer components, can automatically reset after overload disappears, achieving multiple overcurrent circuit protection. When a conductive polymer is heated by an overload current, its resistance will increase, thereby limiting the circuit current. The advantages are more prominent in many products. However, it is not possible to replace disposable fuses with self restoring fuses. Both have their own advantages and disadvantages. In terms of overload protection for circuits, the two do not have the best products. Only by fully understanding the performance differences between the two types of fuses can we make easier choices when choosing the optimal circuit protection scheme. Then, based on the specific working conditions of the circuit and different types of fuses, Finally, select the most suitable fuse for the circuit to provide overload protection.

　　　　The operating principle of a self-healing fuse is a dynamic balance of energy. The current flowing through the self-healing fuse generates a certain amount of heat due to the thermal effect of the current (self-healing fuses all have resistance values), and the generated heat is completely or partially dissipated into the environment. The heat that is not dissipated will increase the temperature of the self-healing fuse components. The temperature during normal operation is relatively low, and the heat generated and dissipated reaches a balance. The self-healing fuse element is in a low resistance state, and the self-healing fuse does not operate. When the current flowing through the self-healing fuse element increases or the ambient temperature increases, but if the balance between the generated heat and the emitted heat is reached, the self-healing fuse still does not operate. When the current or ambient temperature increases again, the self-healing fuse will reach a higher tempe

Brief Introduction to the Six Factors in Selecting Control Power Fuses.50 amp blade fuse

　　　　As a circuit designer, it is necessary to master how to select fuses. However, in reality, including many engineering designers in large factories, they are not very familiar with or even understand how to correctly select current fuses. The following are several factors that must be considered when selecting current fuses:　　1. Size and appearance:　　I believe everyone knows about the size and appearance of the fuse. The size of the fuse chosen mainly depends on the space of the circuit and the installation method of the fuse. At present, our company's main current fuse sizes include: 8 * 4 * 7 square fuse, 8 * 8 round fuse, 3.6 * 10 (4 * 11) fuse, 5 * 20 fuse tube, 6 * 30 fuse tube, etc. The latter three types of fuses are divided into lead fuse and individual fuse tube.　　2. Rated voltage:　　The voltage of the circuit must be less than or equal to the rated voltage of the fuse. That is to say, if the voltage of the circuit is 125V, both the rated voltage of the selected fuse 125V an

Small volume 0603 series minimum current patch recoverable fuse.resettable fuse 12v

　　　　The minimum current of the brand 0603 series is 0.02A, and the maximum current can reach 1A. All detailed models of the entire series include ASMD0603-002, ASMD0603-003, ASMD0603-004, ASMD0603-005, ASMD0603-010, ASMD0603-020, ASMD0603-025, ASMD0603-035, ASMD0603-050, ASMD0603-075, and ASMD0603-100. Today we will learn about the minimum current of this series.　　The minimum current patch recoverable fuse of the 0603 series corresponds to the model ASMD0603-002, with a silk screen of Y, a rated current of 0.02A, a triggering current of 0.06A, a maximum current of 20A, a maximum voltage of 60V, and a power output of 0.5W during operation. When the current passing through the fuse is 0.2A, the fuse will operate within 1 second. At this moment, the minimum internal resistance of the material number is 12 Ω, and the maximum internal resistance after one hour of welding on the machine is 70 Ω. The normal operating temperature range is -40 ℃~+85 ℃. Welding placement supports two types: refl

How to select a suitable resistive fuse.tube amp blown fuse symptoms

　　　　The specifications of resistance fuses are distinguished based on current. If we choose a fuse with a high rated current, it will not be able to ensure safety during use. So when choosing fuses, everyone must choose according to the actual situation. So how can we choose the most suitable resistive fuse?　　The first point is that everyone should first choose a reliable production enterprise. Only by finding a trustworthy fuse supplier can we obtain the highest quality fuse products from them.　　Secondly, when selecting fuses, we must pay attention to the different materials of fuses that have different usage effects, and choose the appropriate type based on the specific properties of our own production. We may be more concerned about the price of resistive fuses, but with the continuous development and improvement of the entire market, the price of such fuses has been effectively controlled. In other words, as long as everyone purchases through normal channels, they are not afraid to
