The application fields of small fuses continue to expand

With the vigorous development of the electronics industry, the product types and technical functions of small fuses are constantly innovating. Following the development of digital technology and various smart electronics, small fuses will continue to introduce a variety of new product series, including higher rated voltages. , The rated current is larger or smaller, the internal resistance is smaller, the fuse characteristics are more diverse, the breaking capacity is stronger, the recoverable type, and the multi-line array, with intelligent functions, multi-functional integrated components or modules, etc., to Meet the circuit protection needs of more updated terminal products. Sapphire Technology will also develop and introduce more and better quality small fuses according to the different needs of the market.

Main fuse market

In the history of more than one hundred years, fuses have experienced four major historical changes. From the initial protection of the metal alloy wires of incandescent lamps, to the current miniature chip fuses, the development is extremely rapid, and their main markets have also shifted from Europe and the United States to The Asia-Pacific region, especially China, began in the 1990s, and in the past two decades, small fuses have occupied a major share of the fuse market and are continuously expanding. Most of the assembly plants of many electronics companies in the world are located in China, and China’s huge population base determines that the main market for the electronics industry is also in China. These make China the most important market for the fuse industry. According to data, China’s current The actual annual consumption of chip fuses (including Japanese, Korean, Hong Kong and Taiwan-funded factories in mainland China) accounts for about 50% of the global chip fuse consumption and nearly 15% of the total consumption of small fuses.

Continuously expanding application areas

Among the small fuses, the chip fuses, as a new type of component, are suitable for various electronic products with compact structure and small size, especially in the field of digital handheld electronic equipment. Judging from the current data, its application areas are:

Communication field: from base stations, switches to terminals, small fuses are used in all electronic circuits. The most important markets are mobile phones and network and peripheral products, such as mobile phone chargers, switching power supplies, and over-voltage protection for LCD screens. Routers, modems, network cards, etc. around the network.

Computer field: computer motherboards, hard disks, various plates, most of them need small fuses, especially disposable fuses and recoverable fuses, and computer peripheral printers, scanners, copiers and other office equipment are widely used .

Audio-visual equipment: In almost all audio-visual equipment, such as DVD, radio, TV, set-top box, GPS navigator, MP3/MP4, etc., small fuses are used as overcurrent protection.

Small household appliances field: Applications in this field are almost everywhere, such as microwave ovens, soymilk machines, induction cookers and so on.

Digital electronic personal products: the most rapidly developing industries with endless varieties, including digital cameras, palm computers, PDAs, electronic translators, electronic game consoles, multimedia players, learning, and all kinds of new digital electronic products, etc.

Other fields: financial and commercial ATM machines, tax control machines, high-end computers, POS machines, mobile scanners, cash registers, medical equipment, electronic toys, precision instruments, etc.

Prospect

The rapid development of electronic products has promoted the continuous growth of the consumption of small fuses. According to the data, it can be predicted that the consumption of small fuses will increase year by year, but their prices will continue to decline like other electronic products. For fuse manufacturers, only by continuously improving technology, reducing costs, and developing new products can they survive in a more intense future.
