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.
The self-healing fuse PPTC is a type of overcurrent electronic protection component, which is made by adding conductive particle materials to a polymer organic polymer under high pressure, high temperature, and vulcanization reaction conditions, and processed through a special process. Self recovery fuse (PPTC: Polymer self recovery fuse) is a positive temperature coefficient polymer thermistor used for overcurrent protection and can replace current fuses. When the circuit is working normally, its resistance value is very small (voltage drop is very small). When the circuit experiences overcurrent and causes its temperature to rise, the resistance value sharply increases by several orders of magnitude, reducing the current in the circuit to below the safe value, thus protecting the subsequent circuit. After the overcurrent disappears, it automatically returns to a low resistance value. The above is the working principle of a self recovery fuse. Chip self recovery fuse Most people
Patch self recovery fuse (PTC: Polymer self recovery fuse) is a positive temperature coefficient polymer thermistor used for overcurrent protection and can replace current fuses. When the circuit is working normally, its resistance value is very small (voltage drop is very small). When an overcurrent occurs in the circuit, causing its temperature to rise, the resistance value sharply increases by several orders of magnitude, reducing the current in the circuit to below the safe value, thus protecting the subsequent circuits. After the overcurrent disappears, it automatically returns to the low resistance value. SMD self recovery fuses are widely used, so let's take a look at the specific applications of their products. 1. Application in circuit control and sensors: Transistor temperature compensation circuit, temperature measurement and control circuit, overheat protection circuit, incubation box, electric fan, color roll washing, kettle, electric water heater, electric blanket,
Ceramic gas discharge tubes are the most widely used switching devices in lightning protection equipment. Whether it is for lightning protection of AC and DC power supplies or various signal circuits, they can be used to discharge lightning currents into the ground. Its main characteristics are: high discharge current, small interpole capacitance (≤ 3pF), high insulation resistance (≥ 109 Ω), high dispersion of breakdown voltage (± 20%), and slow reaction speed (the fastest is 0.1-0.2 μ s) . According to the number of electrodes, there are two types of discharge tubes: bipolar discharge tubes and bipolar discharge tubes (equivalent to two bipolar discharge tubes connected in series). Its shape is cylindrical, with two structural forms: with and without leads (some also have protective cards for short circuits in case of overheating). A gas discharge tube consists of two electrodes enclosed at a certain distance in a ceramic tube filled with inert gas. Its electrical performance ba
The specifications of resistance fuses are distinguished based on current. If we choose a fuse with a high rated current, it will not be able to ensure safety during use. So when choosing fuses, everyone must choose according to the actual situation. So how can we choose the most suitable resistive fuse? The first point is that everyone should first choose a reliable production enterprise. Only by finding a trustworthy fuse supplier can we obtain the highest quality fuse products from them. Secondly, when selecting fuses, we must pay attention to the different materials of fuses that have different usage effects, and choose the appropriate type based on the specific properties of our own production. We may be more concerned about the price of resistive fuses, but with the continuous development and improvement of the entire market, the price of such fuses has been effectively controlled. In other words, as long as everyone purchases through normal channels, they are not afraid to
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. Glass tube
