1. Exceeding rated power: Fuses have a certain rated power, and when the power of electrical equipment exceeds the rated power of the fuse, it will burn out. The function of a fuse is to protect the circuit and prevent overload. 2. When the current resistance value of the fuse exceeds the rated current value and burns out: When there is a short circuit or poor contact in the circuit, excessive current will be generated, causing the fuse to burn out. At this point, it is necessary to check whether the circuit is normal and whether the current withstand value of the fuse exceeds the rated current value. 3. Use environment of fuses: The service life of fuses is affected by the ambient temperature. If the ambient temperature is too high, the service life of fuses will be shortened and they are prone to burning out. 4. Material of fuses: Fuses made of different materials have different high temperature resistance performance. If the material of the fuse is not suitable, it is also ea
In modern life, cars have become our indispensable companions. However, do you know that protecting your car is not just about regular maintenance and high-quality fuel, but also about those inconspicuous but crucial small components - car fuses. Car fuse is a critical safety device that can quickly cut off the current in case of circuit overload or short circuit, preventing damage to the electrical system and even causing a fire. Our car fuses are made of high-quality materials with excellent conductivity and high temperature resistance, ensuring stable operation under various extreme conditions. Choosing our car fuses is not only about caring for your beloved car, but also about ensuring your own safety. Let us provide comprehensive protection for you and your family, ensuring that every trip is worry free.
Fuse is a key component used for circuit protection, mainly to cut off the current when the circuit is overloaded or short circuited, in order to protect the safety of electrical equipment. According to different applications and characteristics, fuses can be divided into the following three categories: 1. Plug in fuse: This type of fuse is usually used in cars and some household appliances. Its characteristics are easy installation and easy replacement. The plug-in fuse has a rated current value, and the selection needs to be matched according to the operating current of the circuit. 2. Spiral fuse: This type of fuse is commonly found in old-fashioned electrical equipment, characterized by the fuse being wrapped around a ceramic core and then wrapped in a layer of glass or plastic shell. The replacement of spiral fuses is relatively complex, but they have strong resistance to high voltage and high current. 3. Surface mount fuses: With the development of electronic technology, s
Protecting the safety of circuits is crucial in modern electronic devices. We are proud to introduce the latest low-temperature fuse technology to provide excellent protection for your equipment. Low temperature fuses adopt advanced material science, which can respond to temperature changes in a very short time, ensuring that the circuit will not be damaged due to overheating. Product features: -Quick response: Low temperature fuses can cut off current in milliseconds to prevent circuit overheating. -High reliability: Made of high-quality materials to ensure stable performance in extreme environments. -Environmentally friendly design: lead-free, halogen-free, compliant with RoHS standards, green and environmentally friendly. Applicable scenarios: -Consumer electronics: smartphones, tablets, laptops, etc. -Automotive electronics: electric vehicles, auto drive system, on-board entertainment system, etc. -Industrial control: automation equipment, robots, smart factories, etc.
The resistance value of the fuse resistor is relatively small, generally ranging from 0.33 Ω to 10K Ω, and the power is also small. Attachment 1: Differences between current fuses and wire wound fuse resistors 1. The current fuse does not consume energy, generate heat, or melt, and the latter will not melt when the resistance value is selected higher. 2. The current fuse is short and cannot be adjusted, and the resistance value is not optional. The latter has an adjustable fuse length and resistance value. 3. The use of current fuses should be coordinated with NTC, which can be used separately. 4. The current fuse does not absorb abnormal surges and lightning surges, while the latter can absorb and have strong resistance to lightning surges and abnormal surges.
The fuses commonly used in PCB boards of small household appliances use self recovery fuses to protect the circuit. The selection of self recovery fuses in small household appliances can be divided into the following steps: Firstly, determine the working voltage of the self recovery fuse; 2. Based on the actual average operation of different products, determine whether the self recovery fuse is the inactive current; 3. The maximum current ratio, temperature, and other parameters of household small appliances in actual work, as well as the time required for self recovery fuse self correction (self recovery fuse action current amplification or reduction); 4. Revise it to an actual experiment and ensure that there is no false protection work, but it is necessary to self recover the fuse parameters within the specified time and protect the motor from stalling. The change in the thermistor of a small motor is an easy choice, but after repeated experiments, the thermal resistance of
