The influence of actual working current on fuse selection.are plastic fuse boxes legal

　　　　1. It should be noted that in the early stages of understanding the normal working current of a product, it is often not particularly accurate. Because an electronic engineer often amplifies the parameters naturally and habitually when selecting device models, such as the actual measurement value being 0.42A, but habitually setting it at 0.5A, and may even consider it safe to perform some amplification, setting it at 0.8A. This is a common practice for electronic engineers when selecting self restoring fuses.　　2. For some products, when the current is not constant, the maximum current of the product is often taken as the normal working current. Therefore, it is necessary to understand at this time:　　A. The current at which the product operates for a long time (usually);　　B. The duration of the maximum current;　　C. The frequency (time interval) of the maximum current repetition.　　When the maximum peak current of the product is not very large (less than twice), the duration is not ve

battery distribution fuse block.Usage and precautions for self restoring fuses

　　　　With the widespread application of self restoring fuses in the electronics industry in Shenzhen, we are paying more and more attention to the safety of electronic products. We need to know the performance of the products used　　Among the technical indicators of PPTC, one is Vmaxi, which represents the maximum voltage that the self recovery fuse protector can withstand in a blocked state. That is to say, in a circuit where the self recovery fuse is connected in series, when the current of the circuit is abnormal, the self recovery fuse will jump from low resistance to high resistance within a certain time range, thereby preventing the flow of abnormal large current and protecting the subsequent circuit from being damaged by large current. At this time, almost all of the voltage of the circuit is added to the self recovery fuse.　　If the voltage applied to the self recovery fuse exceeds Vmaxi at this time, it is easy to cause damage to the self recovery fuse, causing permanent damage a

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

Solution to fuse failure.a plug fuse is typically used in a

　　　　1. Replace with a suitable fuse model　　Don't rush when a fuse malfunctions. Disconnect the circuit first, eliminate the problem, and then replace it with a new one. The quality and model of the new fuse must meet the specified range of the circuit.　　2. Perform an overload test on the fuse　　Conducting overload testing on fuses can effectively detect the quality of the fuses and select appropriate fuse models. After being tested on the machine and found to be fine, they can be installed and used.　　Can the fuse still be used after the circuit is overloaded?　　Answer: Whether the fuse can still be used after the circuit is overloaded depends on the type of fuse you installed in the circuit. If a disposable fuse is used in the installation circuit and the fuse blows after the circuit is overloaded, a new fuse needs to be replaced. If a self restoring fuse is used, the fuse will automatically block excessive current in the event of overload. After troubleshooting, the fuse can automatical

　　　　1. When operating at a normal operating current of 25 ℃, the current rating of the fuse should usually be reduced by 25% to avoid harmful blowing. Most traditional fuses use materials with lower melting temperatures. Therefore, this type of fuse is relatively sensitive to changes in ambient temperature. For example, a fuse with a current rating of 10A is usually not recommended to operate at an ambient temperature of 25 ℃ and a current greater than 7-5A.　　2. The voltage rating of the fuse must be equal to or greater than the effective circuit voltage. The general standard voltage rating series are 32V, 125V, 250V, and 600V.　　3. The resistance of a resistor fuse is not important in the entire circuit. Since the resistance of a fuse with an amperage less than 1 is only a few ohms, this problem should be considered when using a fuse in a low-voltage circuit. Most fuses are made of materials with a positive temperature coefficient, so there are two types of resistors: cold resistance a
