　　　　When current flows through a conductor, it will generate heat due to the presence of a certain resistance in the conductor. And the calorific value follows this formula: Q=0.24I2RT; Where Q is the heat generated, 0.24 is a constant, I is the current flowing through the conductor, R is the resistance of the conductor, and T is the time for the current to flow through the conductor; Based on this formula, we can easily see the simple working principle of a fuse. When the material and shape of the fuse are determined, its resistance R is relatively determined (without considering its resistance temperature coefficient). When an electric current flows through it, it generates heat, and as time increases, its heat also increases. The magnitude of current and resistance determines the rate of heat generation, while the construction and installation of a fuse determine the rate of heat dissipation. If the rate of heat generation is less than the rate of heat dissipation, the fuse will not

resettable surface mount fuse

　　　　Low resistance current fuses are designed to provide protection with minimal impact on the electrical circuit's performance. Here's an in-depth look at these fuses.　　One of the main advantages of low resistance current fuses is their ability to handle high currents with minimal voltage drop. This is particularly important in applications where power efficiency is critical, such as in high-performance electronics or power distribution systems.　　These fuses are typically made of materials with low resistivity, such as copper or silver. The construction of the fuse is designed to ensure a low resistance path for the current while still providing reliable protection in the event of an overload or short circuit.　　Low resistance current fuses often have a fast-acting response time. This means they can quickly interrupt the circuit when an overcurrent condition occurs, minimizing the potential damage to the connected equipment.　　In applications where space is limited, low resistance curre

　　　　Low zero power resistance: The self resetting fuse has low impedance, low power loss during normal operation, and low surface temperature.　　Fast overcurrent protection speed: Due to its material characteristics, the self resetting fuse has a much faster response speed to overcurrent conditions than other overcurrent protection devices.　　Self locking operation: The self resetting fuse is in an overcurrent protection state, locked in a high resistance state with minimal current. Only after cutting off the power supply or the overcurrent disappears, can the low resistance state be restored.　　Automatic reset: The self resetting fuse resets itself after providing overcurrent protection (troubleshooting), without the need for replacement.　　High current resistance: Self restoring fuses have excellent high current resistance, and some specifications can withstand 100A current impact.　　Application: PPTC has a wide range of applications and can be used in various electronic products, communi

Application of SMD fuses in independent equipment.samsung tv ceramic fuse replacement

　　　　SMD fuse, also known as SMD chip fuse, is a type of SMD packaged fuse that has a wide range of applications due to its small size and chip type. Its application in some independent devices is gradually playing an irreplaceable role.　　The scope of battery powered equipment has expanded from powerful hand tools for craftsmen to sensors for housing supervision and even medical assistance services. The security of such devices faces enormous challenges. To ensure safe operation of these independent devices, JDTFUSE offers two SMD fuses with low power consumption and high tolerance tripping time.　　In 2010, billions of lithium-ion batteries were manufactured worldwide. At the same time, the application fields of these products are also constantly expanding. Currently, battery powered devices are ubiquitous. Although these convenient tools are very practical, they have always been a source of danger. This type of equipment is prone to fire, and excessive current can also damage the circui
