When an overload occurs, a disposable fuse will blow at once. Although it can provide overcurrent protection, it needs to be replaced. The core part of a conventional fuse is a section of wire, which is heated to the melting point when the current is too high. After the wire melts, the current in the circuit drops to zero. So in some circuits that require complete power outage, or products with higher risk factors such as machinery, it is more suitable to use disposable fuses, which has a higher safety factor when used. Both traditional disposable fuses and self restoring fuses can achieve overcurrent circuit protection. Both achieve protection by reacting to the heating phenomenon generated by excessive current in the circuit. Fuses break the current by blowing, while self restoring fuses rely on changing from a low resistance state to a high resistance state to limit the magnitude of the current.
How to choose between traditional disposable fuses and self restoring fuses, as there are significant differences between these two components? Next, we will provide a detailed introduction to the advantages of these two types of fuses, making it easier for everyone to better understand these two products and choose the fuse they need. Many designs such as computers, peripheral devices, and portable devices (such as smartphones, tablets, etc.) require the use of self recovery fuses because the self recovery function provided by self recovery fuses is more suitable for use. If ordinary disposable fuses are used, they need to be replaced every time the circuit is abnormal or overloaded, and replacing fuses for these products is very troublesome. Therefore, using self restoring fuses on these products can not only protect the product's service life, but also improve usage efficiency. The principle of self restoring fuses is to limit potentially harmful overload currents within a saf
The word 'FUSE' is often heard in today's society, and some people may joke that your fuse has burned. What should we do at this time. What are the parameters of the patch self recovery fuse? You don't understand anything, but it's okay. We have professional engineers who handle professional matters. What does the parameter of patch self recovery fuse mean? What do parameters refer to? If it is a plug-in, divide the current and voltage, and the patch self recovery fuse depends on its volume Fuses are overcurrent electronic protection components that use high molecular organic polymers under high pressure, high temperature, and sulfurization reaction conditions. The usage standards of different self resetting fuses also change with each other Where are the parameters of SMD self recovery fuses generally used? SMD self recovery fuses are a new generation overcurrent protection device with high reliability, convenient installation, and can automatically recover and be used multiple
A netizen left a message asking: How do you understand the difference between maintaining current and triggering current of a fuse? Fuses all have a holding current and a triggering current. Below, the editor will analyze the difference between the holding current and triggering current of fuses. The holding current (IH) is the highest current that can pass through the circuit without triggering a resistor in still air (ranging from 20 ℃ to 25 ℃ depending on the temperature of the product), which is the highest operating current at room temperature. The triggering current (It) is the minimum current at which the Lite fuse operates in still air (which can range from 20 ℃ to 25 ℃ depending on the temperature of the product), i.e. the minimum fault current at room temperature. For most fuse products, the ratio of It to IH is 2:1, which may be as low as 1.7:1 for some products and as high as 3:1 for others. The difference in materials and production methods, as well as the change i
Attention should be paid when purchasing SMD fuses. If the fuse is not original, has undergone secondary processing or multiple uses, the quality of the fuse is not guaranteed, and problems may occur during use. The original SMD fuse, as long as it is a qualified product, can timely disconnect the circuit in case of overload and short circuit, protecting the product from damage. So how do I know if the purchased SMD fuse is original? 1. Is the packaging of the SMD fuse intact Generally, fuse manufacturers have markings (markings, numbers, etc.) on the packaging of fuses. The packaging materials and methods must comply with standard regulations, and the internal and external packaging of the product must be firm, complete, dry, and clean. If the import and export trade contract complies with the packaging materials, packaging methods, and padding requirements, it must also comply with the contract provisions. After receiving the patch fuse, it is necessary to check whether the pac
The response speed of a fuse is related to the operating temperature of the circuit where the fuse is installed, the fault current, and the heat dissipation of the device. The working environment of the circuit changes, such as when the working temperature of the circuit increases beyond the limit that the circuit can withstand, the fuse will act and blow. The higher the temperature of the circuit, the faster the response speed of the fuse, usually within a few seconds; The better the heat dissipation, the slower the reaction speed, usually around one minute. The same device can operate with a time difference ranging from a few milliseconds to a few seconds under different conditions. But if the overload current of the circuit is dozens or even hundreds of times the normal working current of the circuit, the fuse will burn out before it can blow. Therefore, everyone should choose a fuse based on the actual circuit situation, so that the fuse can respond in a timely manner to prote
