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
Why sometimes patch type fuses become highly resistant and we know that the operating principle of tubular fuses is: overcurrent causes the thermal balance on the melt to be disrupted, and when the melt temperature rises to the melting point of the metal material, the middle part of the melt changes from solid to liquid. Due to the surface tension and gravity of the metal material suspended in the tube, the liquid part of the melt pulls away from both ends and drops downwards, The flashover caused by voltage causes the melt temperature to continue to rise, further flashover and further widening the distance until the circuit is completely cut off. For patch type fuses, their operating principle is the same. However, due to different structural states, the surrounding of the metal melt is tightly surrounded by the polymer or ceramic materials of its matrix. Even the melted metal cannot contract towards both ends and can only rely on diffusion, infiltration, or absorption towards the
Most circuits generate an instantaneous surge current when the power is first connected. In capacitive or inductive circuits, this surge current is often many times, or even dozens of times, greater than the normal steady-state current. If the surge resistance of the fuse used in the circuit is not strong enough, the fuse will be blown off by high-energy surges. If the duration of this surge current is short and the energy released is insufficient to break the fuse, the fuse will not break and will only be damaged to a certain extent. It will only be broken after a certain number of surge impacts. Similarly, hot swapping of some plug-in components during the operation of the entire machine can generate large pulse currents. At this time, if the fuse's pulse resistance is not strong enough, it will often be blown by the pulse. To avoid fuses being blown off by surges or pulse currents and unable to function properly, we need to choose the correct type of fuse and choose the appropri
