　　Each type of circuit protection component has specifications, and self recovery fuses are no exception. So, what do you think when holding a self-healing fuse specification book? To put it bluntly, when reading the specifications, the main focus is on the parameters and the meanings they represent:

　　I hold: Maintain current

　　I trip: The maximum action time under the specified current;

　　V max: Maximum voltage that can be withstood

　　I max: Maximum current that can be withstood

　　P d: Stable power consumption in high resistance state

　　R: Zero power resistance measured at a certain temperature

　　R 1max: The maximum resistance value measured at room temperature after one hour of action or soldering back

　　Environmental temperature: The temperature of the still air around PTC

　　Maximum working environment temperature: The highest ambient temperature for PTC safe operation

Overload protection of self recovery fuse on charging battery circuit

　　　　Rechargeable batteries, as an indispensable energy supply method in modern life, have been widely used in various devices such as mobile devices, smartphones, electric vehicles, etc. However, in the event of prolonged charging or charger failure, the charging battery may experience overload, which can cause danger. To address this issue, we recommend using self recovery fuses for overload protection on rechargeable batteries, providing comprehensive safety protection for your device.　　self recovery fuse is an intelligent electronic protection component that rapidly increases impedance and limits the flow of current when the current exceeds the rated current, thereby protecting rechargeable batteries and devices from the harm caused by overcurrent. Now, we will focus on the advantages of self recovery fuse in overload protection of rechargeable batteries.　　Firstly, the application of self recovery fuse on rechargeable batteries helps to prevent damage from overcurrent to the battery

Characteristics of fuses and fuses.resettable pptc fuse

　　　　For the melt, its operating current and operating time characteristics are the ampere second characteristics of the fuse, also known as the inverse time delay characteristics, that is, when the overload current is small, the fusing time is long; When the overload current is high, the fuse time is short.　　Our understanding of the ampere second characteristic can be seen from Joule's law that Q=I2 * R * T. In a series circuit, the R value of the fuse remains basically unchanged, and the heat generated is proportional to the square of the current I and the heating time T. This means that when the current is high, the time required for the melt to fuse is shorter. When the current is low, the melting time required for the melt to melt is longer, and even if the rate of heat accumulation is less than the rate of heat diffusion, the temperature of the fuse will not rise to the melting point, and the fuse will not even blow. So, within a certain overload current range, when the current re

air conditioner fuse block pull-out.What are the differences in performance and applications between slow blown fuses and fast blown fuses?

　　　　The main difference between slow fuse and fast fuse is its ability to withstand instantaneous pulse current, which means that it can withstand the impact of surge current when switching on and off the machine without action, thus ensuring the normal operation of the equipment. Therefore, slow fuse is often referred to as surge resistant fuse. From a technical perspective, slow melting fuses have a large melting heat value of I2t, and the energy required for fuse melting is relatively high. Therefore, for fuses with the same rated current, slow melting has a much stronger ability to withstand pulses than fast melting.　　Due to the fact that the I2t of a slow fuse is larger than that of a fast fuse of the same specification, the fusing time in the event of overcurrent in the circuit will also be slower than that of a fast fuse. Is it possible that the protection performance may be worse than some people are concerned about? We said no! Because once a circuit malfunctions, the overcurr

Self inspection method for waterproof fuse holder.ptc resettable fuse tutorial

　　　　After a period of application, waterproof fuse holders are likely to encounter some difficulties. Therefore, in the case of application, it is necessary to frequently inspect them, and its appearance should be inspected first. Based on years of experience, Linda will provide the following:　　(1) Look at its appearance, feet, and surface areas. There are signs of rusting, deformation, or broken feet on the wood.　　(2) Check the surface of the waterproof fuse holder for any contamination or scratches.　　(3) To see if there are any deformation or cracks, and to ensure excellent practical application results throughout the entire application process, it is necessary to ensure that the appearance meets the requirements.　　It is not difficult to see from this that circuit safety is crucial, especially in hot summer when natural phenomena are still highly prevalent. Against this objective background, it is important to ensure the professionalism of circuit maintenance, especially in troublesh

What is a fuse holder?lighting fuse block

　　　　Fuse holder refers to the holder used for installing fuses, which can be divided into panel mounted fuse holders, PCB mounted fuse holders, lead type fuse holders, and automotive fuse holders; Panel mounted fuse holder (mostly used for electrical equipment, such as power amplifier, DVD, speaker, Massage chair and other electrical equipment); Lead wire fuse holder (mostly used for connection of Small appliance and industrial machinery wire harness); PCB fuse holder (mostly used on the control board of Small appliance) and fuse clip (mostly used on the control board of Small appliance). Car fuse holders can be divided into lead type car fuse holders (commonly used in car and industrial machinery wiring harnesses); Panel mounted automotive fuse holders (commonly used in automotive appliances such as power amplifiers, refrigerators, DVDs, etc.) and automotive fuse clips. Fuse holders have requirements for current resistance, voltage resistance, and fire resistance, and generally requir
