The development trend of circuit protection components is optimistic.glass tube fuse vs blade fuse

　　　　(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 SIA (American Semiconductor Industry Association) statistics, the current working voltage is around 1.5V, and it will drop to below 1.2V by 2004. Therefore, its ability to withstand overcurrent/overvoltage needs to adapt to new protection requirements.　　(3) There are more and more mobile electronic products, such as handheld devices, PDAs, laptops, camcorders, digital cameras, jukeboxes, etc. These electronic products require battery components as power sources, and protective components must be equipped in both battery components and battery chargers.　　(4) In modern luxury

Features of plug-in self recovery fuse.resettable fuse hold current

　　　　PPTC self recovery fuse is an overcurrent protection component that can automatically reset. It is made by adding conductive particle materials to a polymer organic polymer under high pressure, high temperature, and vulcanization reaction conditions, and processed through a special process.　　The PPTC self recovery fuse plug-in packaging series is divided into A6 (6V), A16 (16V), A30 (30V), A60 (60V), A72 (72V), A120 (120V), A240 (240V), A250 (250V), A600 (600V) series, which are distinguished by different withstand voltage values.　　Product features:　　After circuit obstacles are eliminated, the fuse automatically recovers without the need for manual replacement. It can be reused and reduces costs.　　Fast action time and recovery time increase reliability.　　Safety certification: UL, compliant with ROHS certification.　　The PPTC self recovery fuse of the plug-in has higher voltage and greater current than the patch, better meeting customer needs.　　Application:　　Line protection, power ou

Encapsulation Forms of Current Fuses

　　　　The encapsulation of current fuses is an important aspect that affects their performance, durability, and safety.　　Glass Encapsulation: Glass encapsulated fuses are a traditional form. The fuse element is enclosed in a glass tube. The glass provides excellent insulation properties and allows for visual inspection of the fuse element. This is beneficial as it enables users to quickly determine if the fuse has blown, as a blown fuse will show a visible break in the element. Glass encapsulated fuses are commonly used in low power applications such as in consumer electronics. However, they may be more fragile than other encapsulation forms and are not suitable for applications where mechanical shock or vibration is a concern.　　Ceramic Encapsulation: Ceramic encapsulated fuses offer enhanced mechanical strength and better heat resistance compared to glass encapsulated fuses. The ceramic material provides a robust enclosure that can withstand harsh environments and higher temperatures. T
