Application Explanation of Self Recovery Chip Fuses in Microcontrollers.7.5 amp mini blade fuse

　　　　PTC self recovery patch fuse is used for overcurrent protection between motherboard power supplies and backend equipment overcurrent protection. Regarding the issue of PTC self recovery patch fuse for short circuit and overcurrent protection outside the microcontroller. The output port of the microcontroller has direct external wiring. If there is a wiring error, it is easy to burn out the IC. In addition, if there is a load overload, it can also burn out the IC. Therefore, the output port of the I/O port is usually connected in series with a self recovery patch fuse for overcurrent protection.　　In microcontroller circuit protection, disposable fuses or fuse resistors are also used for protection. Glass tube fuses and fuse resistors are traditional protection applications, with the advantage of low cost.　　However, this application has gradually been phased out, and PTC self recovery patch fuses have been used instead. Due to the fact that disposable fuses only fuse for overcurrent

Introduction to the Structural Design of Fuse Tube.pptc fuse full form

　　　　According to different usage requirements, fuse tubes can be divided into two types in structure: lead-free fuse tubes and lead-welded fuse tubes. As shown in the figure, lead-free fuse tubes usually need to be used in conjunction with corresponding fuse holders for easy replacement; Lead soldered fuse tubes can be directly soldered onto printed circuit boards or other circuit components, reducing the spatial position of the circuit.　　The fuse tube can be divided into a glass shell and a hard shell. According to the different melting times, it can be further divided into ordinary fuse tubes, fast melting fuse tubes, and delayed melting fuse tubes. The fusing time of ordinary fuse tubes is relatively slow, but they are inexpensive and can be applied to overcurrent protection circuits with generally low requirements.　　The biggest characteristic of fast fuse tubes is their short fusing time, which is suitable for situations that require quick circuit disconnection. The delayed fuse tu

　　　　(Thermal Links), also known as: Temperature Control; It is a disposable element connected to the circuit with a very accurate and reliable temperature protection circuit. When the working environment temperature exceeds the rated temperature of the Thermal cutoff, the chemical heat sensitive bean in it will generate high temperature and quickly interrupt the circuit, avoiding the harm caused by overheating. After the temperature control fuse blows, it is necessary to manually replace it with a new one to restore normal operation of the circuit.　　Temperature control fuses are widely used in: microwave ovens, Water dispenser, disinfection cabinets, electric irons, toasters, barbecue machines, coffee makers, kettles, dryers, refrigerators, electric water heaters and other electrical equipment.　　The Thermal cutoff has the function of detecting abnormal temperature and cutting off the circuit. It can detect abnormal temperature rise of household or industrial electrical products and qui

automotive blade fuse manufacturers.Discussion on Disposable Blown Fuses

　　　　Disposable fuses can be divided into fast fuse and slow fuse. The models of disposable slow fuse available in Jidian Tong brand include: slow break JFC0603, slow break JFC1206, and slow break JFC2410.　　A one-time slow blown fuse, also known as a delay fuse, has a delay characteristic characterized by its ability to remain intact during non fault pulse currents in the circuit and provide protection against prolonged overload. Some circuits have a current that is several times greater than the normal working current at the moment of switching. Although this current peak is high, it appears for a short time. We call it pulse current, also known as impulse current or surge current. Ordinary fuses cannot withstand this current, and if a regular fuse is used in such a circuit, it may not be able to start normally. If a larger specification fuse is used, it will not be protected when the circuit is overloaded. The melt of the delay fuse is specially processed and has the function of absor

rv air conditioner fuse location.How long does the self restoring fuse operate?

　　　　Is there a relationship between the self recovery fuse and the action time, and what is the action time?　　1. The action time of the self recovery fuse is related to its internal resistance. The higher the temperature, the greater the current, and the higher the resistance value, and the shorter the action time of the self recovery fuse.　　In general, in official language, a self restoring fuse passes through 100% of its current in a room temperature of 25 ℃. However, if the rated current exceeds twice or more, the self restoring fuse will return to operation.　　2. There are self recovery fuses available from a few seconds to tens of seconds, and the duration depends on the specific model of self recovery fuse used, as well as factors such as the characteristics of the fault. The sensitivity is not related to the price, but to the model of the self recovery fuse. The higher the current and voltage, the more expensive the price
