　　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, fluorescent lamp, energy-saving lamp, battery charging, transformer winding, heater, delay device, compressor, color TV, color display, overcurrent protection, liquid level control, electronic ballast, program controlled switch, electronic component aging table. (Recommended reading: Application of self-healing fuses with different voltages)

　　2. Application in electric heating appliances:

　　Warm air heater, warm room dryer, dryer (cabinet), roller dryer, hand dryer, hair dryer, curler, steam beauty salon, rice cooker, mosquito repellent, hand warmer, shoe dryer, high-pressure cooker, disinfection cabinet, kerosene gasifier, electric iron, electric soldering iron, plastic welding gun, sealing machine.

　　3. Application in automobiles:

　　Electrical overload protection devices, hybrid heaters, low-temperature starting heaters, fuel heaters, honeycomb heaters, fuel level indicators, engine cooling water temperature detection meters, electric windows, motors, DC motors, DC cigarette lighters, and adapters.

plastic fuse box under stairs.Discussion on the Application of Fuses on LED Beads

　　　　1、 Firstly, analyze the causes of LED bead damage, which are usually caused by the following reasons　　① A sudden increase in power supply voltage.　　② The temperature inside the lamp is too high　　③ Short circuit in the circuit.　　④ Failure to do a good job in preventing static electricity during assembly has caused damage to the interior of the LED lamp beads due to static electricity. Although normal voltage and current values are applied, it is extremely easy to cause damage to LED beads　　⑤ The voltage and current of the circuit are unstable.　　2、 How to protect the circuit of LED beads?　　Answer: Nowadays, many circuits use fuses for overload protection, but disposable fuses are not suitable for LED lamp products because the circuits of LED beads are very different from those of other products. LED bead circuit overload is caused by the overload protection component, which immediately disconnects the LED bead circuit and automatically restores power supply after the circuit is norma

ge window air conditioner fuse location.What should I do if a fuse burns at home?

　　　　Summer residents are prone to frequent malfunctions in their homes, with blown fuses being one of them. If citizens find that the fuse in their home is burnt out, they should first investigate the cause, which mainly includes three types:　　1. Short circuit fault occurs in the electrical circuit (socket) at home;　　2. Overload electricity consumption;　　3. Quality issues with fuses.　　What to do if a fuse burns at home　　What to do if a fuse burns at home　　1. If there is a short circuit fault in the electrical circuit (socket) at home, it is necessary to first eliminate the fault, and then replace it with a new fuse (fuse) or replace it with an air switch of corresponding capacity;　　2. If it is overloaded with electricity, replace it with a new fuse or install an air switch of corresponding capacity to reduce the number of household appliances used simultaneously (especially high-power household appliances);　　3. If the above two fault causes are eliminated, namely the quality problem of

The Protection Application of Self Recovery Fuses in Electric Toys.fast acting fuse bussmann

　　　　With the development of technology and social progress, people are paying more and more attention to the intellectual development of infants and young children. Various educational toys are springing up one after another, including electric and non electric ones, with thousands of types and varying quality requirements.　　When people purchase toys, they often pay more attention to their playable functions and neglect their safety. Many toy quality issues are only taken seriously when accidents occur, but it is too late and have already caused harm to people, some of which may last for a lifetime.　　In foreign countries and particularly developed countries, the safety of electronic toys is the most important. Regardless of certification, testing, research and development design, customer requirements, etc., the first consideration is safety, followed by the functions of toys, especially electric toys. Therefore, the safety protection of toys is the primary issue. In clause 3.6.2 of th

motorcycle blown fuse symptoms.The Price Trend and Future of Fuses

　　　　We know that in recent years, especially since 2016, domestic factories have increased their machinery and equipment on a large scale, especially the increase in square and SMD fuse automata, which has led to a continuous decline in these products in China. Especially, the price of square fuses has become transparent to the point where customers do not want to negotiate. There are actually several reasons for this situation:　　1: It is the continuous decline of the Chinese yuan, the constant hovering of the US dollar exchange rate, and the depreciation of the Chinese yuan　　2: There are too many homogeneous products, and in order to win more orders, we can only continuously compress profit margins, which is a common problem in the domestic manufacturing industry　　3: After the tax increase in the United States, many orders have been sharply reduced, especially the significant impact of large customer revenue, further forcing fuse factories to compress profit margins and dilute operati

fast acting fuse is used for protection against.How does a fuse work?

　　　　We all know that 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 Shenzhen fuses. Once the material and shape of the fuse are determined, its resistance R is relatively determined (without considering its resistance temperature coefficient). When current flows through a fuse, it will generate heat, and as time increases, its heat also increases. The magnitude of current and resistance determines the speed at which a fuse generates heat, while the construction and installation of a fuse determine the speed at which heat is dissipated. If the speed at which heat is generated is less
