　　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

Definition of high-voltage fuse.mini cooper fuse box

　　　　ISO-8820 and QC/T420-2004 standards define it as a fused protective device connected to a circuit that disconnects the circuit when the current exceeds the specified value and time. A fuse is a thermal response device, and the fuse or fuse in the fuse is made of a fusible alloy with high resistivity or a good conductor with a smaller cross-sectional area. In order to protect the wiring harness and other equipment, it is intentionally designed and manufactured as the weakest part of the circuit. Under normal working conditions, the fuse or fuse in the fuse will not blow; When a short circuit or severe overload occurs in the system, the fuse or fuse will immediately melt, thus protecting the circuit and electrical equipment　　In order to ensure the safe operation of the vehicle's electrical appliances and ensure the proper function of the fuse, it is particularly important to choose the appropriate type and specification. The selection of fuses involves the following factors: current

What happens if a car fuse is damaged.bussmann fast acting fuse

　　　　The function of car fuses is to maintain circuits (routes) and electrical and mechanical equipment. A car fuse is a type of current fuse. When the circuit current exceeds twice the rated voltage of the fuse, it will melt within a few seconds and have the effect of circuit maintenance. Commonly used for overcurrent protection in automotive circuits.　　What happens when a car fuse is damaged? The situation is as follows:　　1. The car cannot start a fire, and the ignition coil has no power. It is necessary to check if the fuse of the ignition coil is damaged, causing the ignition coil to have no working voltage;　　2. The car mounted cigarette lighter cannot be used, and it is necessary to check whether the commercial fuse of the car mounted cigarette lighter in the fuse box is damaged;　　When the vehicle is driving, the speedometer is zero and the ABS warning light flashes, but the speedometer is normal and the fuse that matches the ABS is burned out.

bs 1362 fuse operation characteristics.The difference between self recovery fuse and blown fuse

　　　　In the circuit protection scheme, is it better to choose a self recovery fuse or a blown fuse for overcurrent protection? This issue has always been a serious issue that electronic security engineers must take seriously, and it is also one of the many questions that buyers consult with. In smart consumer electronics products (such as computers, smartphones, tablets, etc.), circuit protection design requires the use of self-healing fuses. If a blown fuse is used, it needs to be replaced every time abnormal overcurrent occurs, which is unacceptable to end users. In situations where safety needs to be prioritized or damage to other downstream circuit equipment needs to be avoided, it is better to choose a fused fuse. In case of a fault, completely cutting off the current is beneficial for fault diagnosis.　　So, what is the difference between a self restoring fuse and a blown fuse? Dongwo Electronics, a comprehensive manufacturer of circuit protection components, has rich practical appl

　　　　Fuses, commonly used in electronic products, mainly play a protective role. And fuses have different safety standards, and the certification of fuses varies from country to country. Let's learn about the safety standards of fuses together.　　Fuse safety standard 1: UL and CSA standards　　Safety standards for North American regions such as the United States and Canada; The standards for small current fuse tubes are UL248-1/14 and CSA248-1/14.　　Fuse Safety Standard II: IEC Standard　　International Electrotechnical Commission standards, safety standards used in Europe and China. The standard for small current fuse tubes is IEC60 127 and GB 9364 (China).　　Fuse Safety Standard III: KTL Standard　　Korean Electrical Safety Standards.　　Fuse Safety Standard 4: JIS Standard　　Japanese Electrical Safety Standards. The standard for small current fuse tubes is JIS C6575.

Reasons for the increasing importance of circuit protection components.china hs code for fuse

　　　　In daily life, electronic products are everywhere, and circuit protection has become increasingly important. In order to make circuits safer, engineers are constantly studying the safety and reliability of products. The main reasons for this are as follows:　　(1) With the demand for the development of electronic products, the functionality (integration) of ICs is also becoming stronger, and their "value" is naturally becoming more noble, so it is necessary to strengthen protection.　　(2) In order to reduce power consumption, reduce heat generation, and extend service life, the working voltage of semiconductor components and ICs is getting lower and lower. According to statistics from the American Semiconductor Industry Association, the current working voltage is around 1.5V, which will decrease to a lower level in the following years. Therefore, its ability to withstand overcurrent/overvoltage needs to adapt to new protection requirements.　　(3) There are more and more mobile electron
