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
Chip fuses are crucial for electronic devices such as digital cameras, laptops, and mobile phones.. From traditional glass test tube fuses to small fuses and patch fuses, the focus of their selection is slightly different due to the differences in new technologies of the products. (1) Current in the normal operation of the circuit. According to the operation of the fuse, the current should not exceed 75% of the rated current of the fuse. (2) Single pulse, impulse current, Surge protector current, operating current and circuit instantaneous value. Please note this when integrating IC fuses. Due to the processing technology caused by small specifications, the impact resistance of built-in fuses is much lower than that of glass tube fuses with the same rated current or other oversized fuses. (3) The size of overload current and the minimum and longer duration of overload current. It is generally necessary to use digital oscilloscope detection and conceptual calculation to distingui
According to the application category, fuses are classified into four categories: power engineering fuses are classified according to rated current, and fuses are divided into three categories based on working voltage: high voltage fuses, low voltage fuses, and working voltage fuses. According to the classification of final breaking capacity, fuses are classified as follows: high breaking capacity fuses are classified by appearance, and fuses are classified as follows: small flat head tubular fuses Fuses are generally divided into two types: disposable fuses and self repairing fuses. Fuses, also known as amperage fuses, are primarily used for load protection. Properly installing a fuse in the power circuit will cause the fuse to melt and interrupt the amount of current in the event of an abnormal increase in voltage to a certain level and attention, protecting the safe operation of the power circuit. Self repairing fuse is a type of overcurrent electronic device protection compon
The general classification and zoning of fuses are generally based on eight levels: protection method, application scope, volume size, rated current, final breaking capacity, external characteristics, melting rate, and standard. 1. Classification by protection method There are two types of fuse protection: overcurrent protection and overtemperature protection; The fuse used for overcurrent protection is the overcurrent protection fuse, and the fuse used for over temperature protection is the temperature fuse. Temperature fuses are also divided into low melting point alloy shapes, temperature sensor open shapes, memory alloy shapes, etc. Temperature fuses are used to protect appliances that are hot or prone to overheating. They respond to the rise in temperature of electrical appliances and do not easily pay attention to the size of electrical flow in the operation of power circuits. Their principle is different from the "overcurrent protection fuse". 2. Classification by applica
1. Unauthorized modification of vehicle lights Many car enthusiasts are fond of modifying high-power headlights or xenon lamps. However, if the vehicle's headlights exceed the original overall planned output power or have a large load, it is inevitable that the fuse will melt. Suggest that if there is insufficient technical expertise or no need to tamper with the modification of cars. 2. Modify a high-power speaker Some buyers want to have the actual effect of Auditory system, which may be modified. But when the output power and disorder of the speaker exceed the original overall plan, the fuse will also melt. 3. Rinse the engine hood with tap water Many people wash their cars in the wrong way. For example, in the summer, many people require a water gun to wash the engine hood when washing their cars, and using a high-pressure water gun with such a high pressure to clean the engine hood can also easily cause short circuit faults in the power circuit.
The starting time of protection has regularity, firstly, it is inversely proportional to the size of the components; Compared to the size of electronic devices, i.e. in the same series, such as the software fuse of the 250V series product, the smaller the current, the smaller the electronic device, which is twice the normal current. Due to its small size, fast heating, and faster startup protection time. Compared to the size of the fault current, it is easy to understand that the larger the fault current, the faster the component heats up and the faster the protection. When selecting a self recovery fuse, we all want to know whether the startup protection rate of the self recovery fuse is sufficient and immediate when a fault current occurs in the power circuit to protect the power circuit machine equipment. There are many models of self recovery fuses, and the starting protection rate varies among different models. And the time period required for starting protection under diffe
