Delay fuse principle.carrier fuse

　　　　Under the same overcurrent load conditions, the action speed of a delay fuse is slower than that of a fast blown fuse. However, this is not that the reaction speed of a delay fuse is slow, but rather that the energy required for the fuse to fuse is greater. It can be said that it not only has the ability to react to overcurrent, but also has the ability to distinguish the category or energy size of overcurrent. Generally speaking, overcurrent can be divided into two categories: surge and fault. Surge overcurrent is mostly caused by charging and discharging during circuit switching or the influence of surrounding circuits. The peak value of the pulse is large and the duration is short, and the energy released is often not large. Delay fuses can withstand such overcurrent impacts without causing fusing action; However, fault overcurrent is continuous, and even if the peak value is not necessarily high, its energy will greatly exceed the surge overcurrent. Delay fuses will usually rea

　　　　1. Voltage Ratings:　　The voltage rating of the fuse must be greater than or equal to the high voltage of the disconnected circuit. Due to the very low resistance of the fuse, the voltage rating of the fuse becomes important only when the fuse attempts to blow. After the fuse element melts, the fuse must be able to quickly disconnect, extinguish the arc, and prevent the open circuit voltage from triggering the arc again through the disconnected fuse element.　　2. Current Ratings:　　The current rating indicates the current carrying capacity of the fuse under a set of test conditions. Each fuse will indicate the current rating, which can be marked with numbers, letters, or colors. The meaning of each marker can be found through the product data table.　　3. Breaking Capacity/Interrupting Rating:　　The fuse must be able to disconnect the faulty circuit without damaging the surrounding circuit. Breaking capacity refers to the current value at which a fuse can safely open a circuit without da

Analysis of the Future Development Status of Fuses.power probe fuse voltage drop chart

　　　　This is an information age, a major era in which smartphones and other smart mobile devices are thriving. People are no longer satisfied with their phones being able to only make phone calls and text messages, and even begin to be dissatisfied with some of the existing intelligent functions. With the prevalence of mobile 4G networks and the expansion of people's visual and tactile senses, smartphones have continuously acquired new technologies, truly achieving rapid breakthroughs and development.　　On this basis, we found that the hardware configuration of mobile phones is getting higher and higher, and it was not long before computers entered the four core era, and mobile phones also followed closely into the four core era; As the size increases, a 5-inch screen is no longer uncommon, and there is a trend towards larger screen sizes. In the near future, there will be a blurry boundary between smartphones and tablets that is difficult to distinguish.　　But the problem lies here as we

　　　　1. When the melt melts, it is necessary to carefully analyze the reasons for the melting, which may include:　　(1) Normal fusing due to short circuit fault or overload operation;　　(2) If the melt is used for too long, it may break due to oxidation or high temperature during operation, resulting in changes in the characteristics of the melt;　　(3) There is mechanical damage during the installation of the melt, which reduces its cross-sectional area and causes accidental disconnection during operation.　　2. When replacing the melt, it is required to:　　(1) Before installing a new melt, it is necessary to identify the cause of melt melting. If the cause of melting is not determined, do not replace the melt for trial delivery;　　(2) When replacing a new melt, check whether the rated value of the melt matches the protected equipment;　　(3) When replacing a new melt, it is necessary to check the internal burn condition of the fuse tube. If there are severe burns, the fuse tube should be replac

Parameters and characteristics of commonly used 40A disposable fuse.tv keeps blowing fuse

　　　　The segmented capacity of the 1206 series 40A disposable fuse is as follows. When the current passing through the fuse is 40A, the fuse can maintain internal fusing for at least 4 hours. However, when the current passing through the fuse is 3.5 times the rated current, which is 140A, the fuse will fuse within 5 seconds, thereby protecting the board. The size specification of this part number is: 3.2mm * 1.6mm, with a thickness of 0.75mm　　The 1206 series 40A disposable fuse has set industry standards in terms of performance, reliability, and quality. The solderless design provides excellent switching and temperature cycling characteristics during use, and enables our SMD fuses to have higher heat resistance and impact resistance than other subminiature fuses.　　The main characteristics of the 1206 series 40A disposable fuse include: ① rapid fusing; ② Reflow soldering and wave soldering are compatible; ③ Ceramic and glass structures; ④ It belongs to the disposable fuse type; ⑤ Lead fr
