Description of Metal Materials for Self Recovering Fuses

　　　　Everyone knows about fuses, but the self recovering fuse (PPTC) in fuses may not be well understood.　　In fact, PPTC self-healing fuses, like the fuses we all know, play a role in limiting current and achieving circuit protection. Simply put, once the current in the circuit exceeds the specified current, it will cut off the current.　　In daily life, the application of fuses can be seen everywhere, such as in household appliances. But do you know what material it is made of?　　Self recovery fuse is an innovative type of fuse with more technical content and wider application range than ordinary fuses. It has the characteristic of being recoverable, so it must use easily melted metal materials to cut off the current in case of overcurrent and achieve protective effect. And this easily melted metal material is usually lead antimony alloy wire.　　Mainly using aluminum alloys with Mg as the main element (Mg based aluminum alloys have good corrosion resistance, strong thermal conductivity, an

Specification and size of patch fuse.tube amp blowing main fuse

　　　　Chip fuses are the most commonly used fuses. As a fuse manufacturer, we also have our own brand of chip fuses. So, what are the specifications and sizes of our company's chip fuses?　　What are the specifications and dimensions of patch fuses—— Chip fuses mainly come in packages such as 0603, 0805, 1206, 1210, 1812, 2016/2018, 2920, etc. They are all named and classified according to volume, and each series has many other specifications and models based on different currents and voltages.　　Surface Mount Fuses　　What are the specifications and dimensions of patch fuses—— Among them, the size of the 0603 series patch fuse is 1.6 * 0.8mm; The size of the 0805 series patch fuse is 2.0 * 1.2mm; The size of the 1206 series patch fuse is 3.2 * 1.6mm; The size of the 1210 series patch fuse is 3.2 * 2.5mm; The size of the 1812 series patch fuse is 4.5 * 3.2mm; The size of the 2016/2018 series patch fuse is 5.0 * 5.0mm; The size of the 2920 series patch fuse is 7.5 * 5.5mm.

　　　　Patch fuses can be divided into disposable patch fuses and patch self recovery fuses. After being protected by a disposable fuse, it needs to be replaced. After being protected by a self recovery fuse, it can be restored and reused after power failure.　　But what should we pay attention to when choosing patch fuses? The editor suggests selecting fuses based on the following aspects: normal current, fusing current, open circuit voltage, short circuit current, impulse current, and ambient temperature.　　Short circuit current: We refer to the maximum current that flows when a circuit is short circuited as the short circuit current. For various fuses, the rated breaking capacity is specified, and we must be careful not to exceed the rated breaking capacity when selecting fuses. If a fuse with a small breaking capacity is selected, it may cause the fuse to rupture or cause a fire.　　Impulse current: Observe the waveform of the impulse current (pulse current waveform) and calculate its ener

　　　　1. Determine the following parameters of the circuit:　　A Large working environment temperature b Standard working current c Maximum working voltage (Umax) d Maximum fault current (Imax)　　2. Select self restoring fuse components that can adapt to the ambient temperature and standard operating current of the circuit　　Use a temperature reduction {ambient temperature (℃) working current (A)} table and select the temperature that best matches the ambient temperature of the circuit. Browse this column to view values that are equal to or greater than the standard operating current of the circuit.　　3. Compare the high electrical rating of the selected component with the high operating voltage and fault current of the circuit　　Use the electrical characteristic table to verify whether the components you selected in step 2 will use the high operating voltage and fault current of the circuit. Check the high operating voltage and high fault current of the device. Ensure that Umax and Imax are g

0.3A self recovery fuse parameters.ceramic fuse sizes

　　　　Fuses can be divided into recoverable and disposable fuses. Recoverable fuses are commonly referred to as self restoring fuses. The biggest functional feature of these fuses is that after the circuit fault is eliminated, the fuse can be restored for recycling; The disposable fuse is what we refer to as a disposable fuse. It is disposable and cannot be reused and must be replaced. Its biggest functional feature is its high segmented ability, which can be divided into fast break and slow break fuses; Fast or slow break refers to the reaction speed of the fuse to the fault current. Today we will learn about the relevant parameters of a 0.3A self recovery fuse.　　There are two types of 0.3A self recovery fuses, domestic and imported. Currently, there are several models of domestic 0.3A self recovery fuses available in stock in Shenzhen, including A6-030, A16-030, A30-030, A60-300, A72-300, ASMD1812-030, ASMD1206-030, ASMD2016-030, and more. Among them, A6-030, A16-030, A30-030, A60-300,
