　　　　In the past few years, surface mount fuses have been the most valuable variety among small fuses, but the price competition they face is also fierce. The average unit price of the product has decreased by 20-30%. In recent years, while surface mount fuses have gained widespread popularity, they have also made continuous breakthroughs and innovations in technology.　　From the perspective of global fuse production distribution, a large proportion of electronic assembly factories are located in China, with over 40% of actual applications in China. The main market of surface mount fuses is in Asia, and is concentrated in Chinese Mainland, Taiwan, Japan and South Korea. Many Japanese and South Korean companies also have factories in China, making China an important market for surface mount fuses.　　The actual annual consumption of surface mount fuses in the former Greater China region (including Japanese, Korean, Hong Kong and Taiwan funded factories in Chinese Mainland) accounts for abou

are plastic fuse boxes legal.The Price Trend and Future of Fuses

　　　　1: It is the continuous decline of the Chinese yuan, the constant hovering of the US dollar exchange rate, and the depreciation of the Chinese yuan　　2: There are too many homogeneous products, and in order to win more orders, we can only continuously compress profit margins, which is a common problem in the domestic manufacturing industry　　3: After the tax increase in the United States, many orders have been sharply reduced, especially the significant impact of large customer revenue, further forcing fuse factories to compress profit margins and dilute operating expenses in order to maintain normal factory operations　　4: A large number of small workshops are squeezing the market and driving down product prices　　For conventional products, prices are gradually decreasing and profits are constantly compressing, which forces many factories to think about where their future profit points are? How to increase the company's revenue! Fuses are affected by price, where is the future?　　So ma

mini blade vs blade fuse.Basic composition of patch fuses

　　　　A general fuse consists of three parts: one is the melt part, which is the core of the fuse and plays a role in cutting off the current when blown. Fuses of the same type and specification should have the same material, geometric size, and resistance value as small and consistent as possible. It is important to have consistent fusing characteristics, and household fuses are commonly made of lead antimony alloy; The second is the electrode part, which usually has two important components that connect the melt to the circuit. It must have good conductivity and should not generate obvious installation contact resistance; The third part is the support part. The melt of the fuse is generally thin and soft. The function of the support is to fix the melt and make the three parts a rigid whole for easy installation and use. It must have good mechanical strength, insulation, heat resistance, and flame retardancy, and should not produce phenomena such as breakage, deformation, combustion, an

pptc fuse full form.What are the characteristics of direct plug-in fuse thermistors

　　　　A thermistor is a type of thermoelectric resistor, and the principle of thermistors is that temperature causes a change in resistance. However, nowadays thermoelectric resistors are generally industrialized, mainly referring to commonly used thermistors such as PT100 and CU50. The difference between thermistors and thermistors is that generally, thermistors refer to metal thermistors (PT100), while thermistors refer to semiconductor thermistors. Due to the temperature coefficient of semiconductor thermistors being more than 10-100 times larger than that of metals, they can detect temperature changes of 10-6 ℃, and the resistance value can be arbitrarily selected between 0.1 and 100k Ω. So it is called a thermistor. The curve of the resistance value of a thermistor with temperature changes is non-linear, and the linearity of each same model is also different, and the temperature measurement range is relatively small. So in industry, metal thermistors are generally used, which is wha

ptc resettable fuse tutorial.Self recovery fuse selection steps

　　　　(1) When used at room temperature of 25 ℃, know the actual average working current I and voltage V at the location where PPTC is installed, regardless of instantaneous current　　(2) Select a self restoring fuse series component based on the I value, V value, product category, and installation method (DIP or SMD).　　(3) If the internal environmental temperature of the device is greater than 25 ℃, the self resetting fuse will reduce the passing current as the temperature increases. To maintain normal load current passing, according to the reduction rate comparison table, calculate Ih (no action current)=I/reduction rate.　　(4) Select the fuse series components according to step (2), and select the corresponding components from the specification table based on the calculated IH value in step (3). It should be emphasized that the IH value of the selected component must be greater than or equal to the IH value calculated in step (3).
