On July 13, Sanan Optoelectronics released the 2012 semi-annual performance forecast. It is estimated that the company's net profit attributable to owners of the parent company in the first half of 2012 will be 450 million yuan to 470 million yuan. The net profit for the same period of the previous year was 45,901,700 yuan, and the net profit attributable to shareholders of the listed company after deducting non-recurring gains and losses was 15,635,370 yuan, and the earnings per share was 0.32 yuan.

Sanan Optoelectronics said that its wholly-owned subsidiary Anhui Sanan Optoelectronics Co., Ltd. has released its production capacity, and its main business income has increased. In the first half of 2012, the net profit attributable to shareholders of listed companies after deducting non-recurring gains and losses was higher than that of the previous year. Over the same period, it increased by more than 90%.

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.
