　　1、 What is fuse resistance?

　　Resistors and fuses are similar in material and construction, while fuse type resistors serve both functions and can be used as resistors to protect machine equipment in case of abnormal current. Due to its dual function, the cost is reduced accordingly. Fuse resistors can be divided into: metal film fuse resistors, fuse type wound resistors, and fuse type cement resistors. There are several types of power: 1/4W, 1/2W, 1W, and 2W. As the power increases, the appearance size of the product will continue to increase.

　　2、 The function of fuse resistance

　　Resistors and fuses are similar in material and construction, while fuse type resistors serve both functions and can be used as resistors to protect machine equipment in case of abnormal current. Usually, the resistance of a fuse is significantly higher than that of an equally long wire, so that it can protect the circuit. If the current or voltage exceeds the rated value, the fuse will blow, causing the circuit to open, thus protecting the electrical appliances. Without a fuse, the circuit and electrical appliances are easily burned out.

Chip fuse specifications | price

　　　　SMD fuse specifications | price - SMD fuses can be divided into SMD disposable fuses and SMD self recovery fuses. Among them, the specifications of patch disposable fuses include series 060312062410 fuses, and the specifications and dimensions of patch self recovery fuses include series 0603, 0805, 1206, 1210, 1812, 2920, etc.　　The price of SMD fuses varies depending on the type. The latest quotation for SMD fuses in the market is around a few cents, with wholesale prices. Good quality products can be sold for around one yuan. There are differences in prices between suppliers and traders, so when searching for products in bulk, it is more advantageous to find manufacturers and suppliers.　　Chip fuse specification | price - The fuse must be a fusible metal wire in order to fuse in a timely manner and provide protection when the current is high. The fuse material is mainly made of low melting point alloys such as aluminum antimony alloy.　　There are four basic forms of patch fuses: slo

　　　　1. How to choose a patch fuse (using well-known brands such as litelfuse bussmann to illustrate the commonly used size of patch fuses 1206 2410 0603)　　Chip fuses are mainly used in electronic products such as digital cameras, laptops, and mobile phones.. From traditional glass tube fuses to micro fuses and chip fuses, the focus of their selection is slightly different due to differences in product technology.　　The selection of patch fuses involves the following factors:　　(1) The normal working current of the circuit. The working current through the fuse should not exceed 75% of the rated current of the fuse.　　(2) Pulse, impulse current, surge current, starting current, and circuit transient values. SMD fuses are particularly concerned about this point. Due to the small size of the fuse, the impact resistance of SMD fuses is much lower than that of glass tube fuses or other larger fuses with the same rated current.　　(3) The magnitude of the overload current in the circuit and the sh

　　　　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

The difference between glass tube and ceramic tube fuses.slow blow fuse vs time delay

　　　　Glass tube fuses can effectively prevent molten metal from splashing onto other devices, while also isolating high temperatures. Ordinary glass tube fuses are commonly used in electronic circuit boards with dense components. Due to their convenient replacement and maintenance, they can also be installed in wires, plugs, or specialized fuse holders; Closed safety tubes can also be used for equipment in explosion-proof locations.　　Glass tube fuses can be divided into: ultra slow fuses (usually represented by TT), slow fuses (usually represented by T), medium speed fuses (usually represented by M), fast fuses (usually represented by F), and ultra fast fuses (usually represented by FF) based on their fusing speed. The diameter of the glass tube is usually φ 5mm, 5X20mm are the most conventional glass tube fuses that comply with the standard IEC60127.　　There are important reasons for choosing glass as the material for fuse tubes, and we have analyzed several main reasons.　　1.

Which is better, disposable fuse or self restoring fuse.surface mount fuse letter code

　　　　From a structural perspective, a self restoring fuse is composed of a polymer polymer, essentially a positive temperature coefficient thermistor. It provides circuit protection through the positive correlation between the resistance value of PTC material and temperature, as well as the sudden change at the Curie temperature point. It can be reused without frequent replacement; Disposable fuses are made of ordinary fuse materials, so they cannot be used again after each action and require frequent replacement.　　From the perspective of working action, they can all be used for overcurrent protection of circuit currents and can be interchanged in many occasions. For example, in battery protection applications where overcurrent protection requirements are not too high, these two types of products can both lead the way and can even be replaced, and most of the time, each has its own field.　　In the protection application of certain important devices such as ICs, or in the input/output ter
