There are three subsidiary companies under SFI Groups, including Sun Flower semiconductor Co., Ltd established in Aug 1999(known as Sun Flower Instruments Inc. established in 1984) is responsible for the production mainly on mono-chip, multilayer chip TVS, advanced varistors etc. and the nearly completed brand factory, Leader Well Technology Co., Ltd for satisfying the tremendous supplies of the worldwide demand on the varistor in the new century, and the mission of SFI Electronics Technology Inc is responsible for the marketing and sales under the independent responsibilities on production, marketing and sales. Advanced Techniques Applied In order to meet the market trend and fast market change, we build our R&D team to control the reliability and stability of the products. We have been utilizing the advanced material and manufacturing techniques on producing the electronic elements and parts. In Taiwan, we are the first company to launch the Zinc Oxide (ZnO) based Ceramic Semiconductor devices with full range and with the highly advanced multilayer formation technologies to apply the high density circuit assemblies. We obtained many kinds of patents and awards for excellent product designs, and had been selected by government to attend the international trade fair on behalf of Taiwan. Our SFI varistors and TVSs reliably protect the electronics systems from overvoltages by limiting surge voltages and by absorbing energy. They are used to safeguard the components, to ensure electromagnetic compatibility and suppress the transients caused by electrostatic discharge. In other words they have the added advantage of greater surge current and energy handling capabilities as well as EMI/RFI attenuation. SFI varistors and TVSs have established themselves as a secure and low-cost means of protection in g.
