Semiconductor Fuse And Ferrite
Fuse refers to an electric appliance that, when the current exceeds the specified value, melts the fuse and disconnects the circuit with the heat generated by itself.When the current exceeds the specified value for a period of time, the fuse melts and disconnects the circuit with the heat generated by the fuse itself.A current protector made from this principle.The fuse is widely used in high and low voltage power distribution system and control system as well as power equipment.
Ferrite is a metal oxide with ferrous magnetism.As far as electrical properties are concerned, the resistivity of ferrite is much larger than that of single metal or alloy magnetic materials, and it has higher dielectric properties.Ferrite magnetic energy also shows high permeability at high frequencies.As a result, ferrite has become a non-metallic magnetic material widely used in the field of high frequency and weak current.Due to the low ferrite magnetic energy stored in the unit volume, saturated magnetic induction strength (Bs) and low (usually only pure iron 1/3 ~ 1/5), and thus limits its higher requirements in the low-frequency magnetic energy density in the field of high voltage and high power applications.

It is understood that there are currently more than 200 companies in Foshan engaged in the production and supporting of LED products, most of the companies are from the traditional lighting into the LED field. With the development of LED technology, the product replacement and replacement speed is fast, and the packaging and marking standards of traditional lamps and lanterns are no longer applicable to LED lamps and lanterns. At present, there are various product types and types of LED products in the market, and the quality is uneven. There are no corresponding national standards, industry standards, and local gesep global energy saving and environmental protection network standards for LED product packaging labels, which affects the stable development of the LED market and the environmental health image of LED. Consumers can't distinguish between good and bad when choosing products, which hinders the promotion of LED products.
In response to the requirements of many businesses on the market, and in order to develop the LED market in a healthy and orderly manner, to solve the problem of inconsistent product identification, Foshan Technical Standards Institute, Foshan Lighting Association, Shunde Lighting Electric Appliances Association, Foshan Guoxing Optoelectronics Co., Ltd. Co., Ltd., Foshan Lanjian Electronics Co., Ltd., Guangdong Zhaoxin Lamps Co., Ltd., Foshan Kaixiou Lighting Co., Ltd. and other leading LED companies, set up a standard alliance to jointly develop LED packaging labeling standards. It took five months of research, data collection, and text formulation (three expert verifications during this period and two online HTTP://WWW.GESEP.COM collection of corporate opinions). Finally, we formulated the “LED Lighting Product Packaging Logo Foshan Alliance Standard†to allow Foshan companies to take a step forward and provide consumers with products that are clear, high-quality, reliable, responsible and responsible, in order to promote the sustainable, healthy and rapid development of the LED industry.
Recently, the reporter learned from the “LED Lighting Product Packaging Logo Foshan Union Standard Press Conference†that the first domestic LED enterprise alliance standard that took five months of research, data collection, and text formulation came out in Foshan.
