Company Profile

SFI, is the trading mark and logo of SFI

Groups, which are established under the

spiritual concept of “Innovation, Services,

Quality, and sincerity”. 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.

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 inter-

national 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 general-purpose use.
