The specific application of patch self recovery fuses.mini cooper fuse box diagram

　　　　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,

The Development History and Trends of Fuses.resettable smd fuse

　　　　1、 Development History of Fuses　　In the 1880s, since Edison invented the light bulb and failed countless experiments on tungsten wire, it also opened up the development history of fuses. The success of light bulbs has also driven the development of fuses. With the development of society and the increasing strength of electrical appliances, the fuse industry has also experienced rapid development.　　The fuse industry in China started relatively late, but has developed rapidly. In 1950, China began to imitate the production methods of the Soviet Union to produce fuses, so the variety of fuses was relatively few, the structure was relatively simple, and the experimental methods were relatively backward. In the early days, the quality of fuses in China was not very good. Until the late 1970s, the emergence of color televisions promoted the development of the fuse industry, and the delay fuses used in color televisions began to move towards international standards. At this time, the fuse

The difference between fuse and circuit breaker.battery fuse blown symptoms

　　　　The same thing is that both can achieve short-circuit protection. The principle of a fuse is to use current to flow through the conductor, causing it to heat up. After reaching the melting point of the conductor, the conductor melts, so disconnecting the circuit protects the electrical appliances and circuits from being burned out. It is an accumulation of heat, so overload protection can also be achieved. Once the melt burns out, it needs to be replaced.　　A circuit breaker can also achieve short-circuit and overload protection for circuits, but the principle is different. It achieves circuit breaker protection through the bottom magnetic effect of the current (electromagnetic release), and overload protection through the thermal effect of the current (not fusing, and there is often no need to replace components). In practice, when the electrical load in the circuit approaches the load of the fuse used for a long time, the fuse will gradually heat up until it blows. As mentioned ab

　　　　1： The testing process is as follows:　　1. Initial internal resistance Rimin measurement: Unpack, take out the fuse, and measure the internal resistance of the fuse;　　2. Welding: Solder the fuse onto the PCB through reflow soldering, with leads connected to the PCB for easy electrical performance testing;　　3. Hold current IHold test: Select a DC constant voltage and current source for testing. Adjust the voltage to the voltage Vmax specified in the specification,　　Adjust the current to the holding current Ihold specified in the specification and power on for 15 minutes;　　4. Action current Itrip test: Select a DC constant voltage and current source for testing. Adjust the voltage to the voltage Vmax specified in the specification,　　Adjust the current to the holding current Itrip specified in the specification and power on for 5 minutes;　　5.
