　　　　1. Product certification. For example, exporting to North America requires UL or CSA certification. At present, products exported to Europe still need to comply with the RoHs directive of the European Union, which is commonly referred to as environmental certification such as SGS.　　2. The normal working current of the circuit. The working current through the fuse should not exceed 75% of the rated current of the fuse.　　3. The applied voltage applied to the fuse. Usually, patch fuses are used in portable devices, and the working voltage of the circuit is generally not high. As long as the rated voltage of the patch fuse is higher than the working voltage of the circuit, it can be used with confidence.　　4. The ambient temperature of the fuse. When applying patch fuses to portable devices, appropriate consideration should be given to the temperature rise of the fuse, that is, the reduction of the rated current of the fuse. The ambient temperature during fuse operation should be within

automotive blade fuse colours.1206 series patch self recovery insurance

　　　　Our self recovery patch fuse 1206 series has a size of 3.2 * 1.6mm, SMD packaging, reel packaging, and a packaging of 3000 pieces. The withstand voltage value ranges from 6V-60V, with a maintenance current of 0.05A-3.5A. As the maintenance current increases, the withstand voltage value also decreases relatively, and the temperature control range is -40+85 ℃.　　Generally, our fuse testing is conducted at room temperature. When customers actually use it on a board, they should also consider the impact of temperature on the internal resistance of the fuse. Generally speaking, as the temperature increases, the internal resistance also increases, and the speed of fuse protection will also be relatively faster.　　The volume of 1206 patch is a commonly used volume for patch self recovery fuses, as it is not as large as the volume of 1812, and is also compared to the volume of 0603 and 0805, which can achieve a wider current range and higher voltage withstand value.　　Our ASMD1206 series is g

littelfuse fast acting fuse.Model and specifications of household fuses

　　　　Fuses are mainly used as basic protective devices for preventing short circuit faults in household appliances. They are generally equipped and selected based on the current of the household appliance. This can be simply calculated by considering current=(power ÷ voltage)&TIMes; 1.5, for example, electrical equipment current=1 kW ÷ 220 V&TImes; 1.5=6.8A, you can choose fuses 6-8A.　　The fusing current of a fuse is usually 1.5-2.0 times the rated current. If the total power of each household appliance exceeds 1100 watts during normal electricity use in a household, choose a 5-ampere fuse and use a No. 20 fuse with a diameter of 0.98 millimeters. When the current exceeds 7.5 amperes to 10 amperes, the fuse will automatically blow to achieve protection.　　SMD fuses are made of lead antimony alloy with high resistivity and low melting point. Its function is to generate more heat when there is too much current in the circuit, causing its temperature to reach the melting point, thereby fusi

mini blade fuse tap Factory.The production method of direct insertion fuse tube

　　　　The utility model is a direct plug-in fuse tube, which belongs to the emergency protection device of a circuit, and is composed of a glass tube, a fuse wire, and a copper cap.　　Generally, emergency protection devices for low-voltage power supply often use knife switches, porcelain fuse boxes, or combination sockets with fuses. It is necessary to open the box cover or unplug the plug to determine whether the fuse of this type of protector has been burned out. However, replacing the fuse requires some tools to replace it, which is quite difficult to lock. In addition, when the fuse is burned out, it generates large sparks, which can easily cause the porcelain body to burn black, bakelite and plastic parts to burn and deform, Especially when the combined socket is burnt and deformed, it cannot be repaired and can only be replaced as a whole, causing significant waste.　　For some low-power household appliances, instruments, and equipment, fuse tubes are often installed inside, and the f

glass fuse holder wholesale.What are the types of ordinary SMD fuses?

　　　　Recoverable fuses are divided into patch self recovery fuses and plug-in self recovery fuses. With the increasing miniaturization of product demand, recyclable patch fuses have been increasingly widely used. The recyclable patch fuse is a new type with high technological content in the small fuse industry. Today we will introduce you to what is a recoverable patch fuse.　　Made of high-tech polymer resin and nano conductive particles through special processing, a repairable patch fuse is made. Normally, nanoconductive crystals form a chain conductive path with resin chains, and the fuse operates normally. When the circuit is short circuited or overloaded, the high current passing through the fuse increases the collection temperature. When the Curie temperature reaches, the density of states rapidly decreases, the phase transition increases, and the internal conductive chain undergoes changes or fractures in an avalanche state. The fuse moves to a high resistance state step by step, a
