Welcome to Yulim Ferrite Co., Ltd.

Yulim Ferrite Co., Ltd. is a manufacturer of ferrite core, and was established in 1965 under the name of Chang il Gong-Up-Sa. In 1970, we succeeded to manufacture Ferrite Core for the first time in Korea using our own developed technology.

In 1981, we changed the company name from Chang il Gong-Up-Sa to Yu Lim Electronics Co.

Our company assembles all of procedures: compounding raw material, forming, cutting, and testing, etc at one location. It is our top priority to meet the specific product demand of our customers as quickly and accurately as possible.

By keeping our production in one location, we are able to deliver urgent sample orders before our competitors.

We are currently developing SMD core and it is very close to practicalization. In addition, we have recently developed the Plasma Rock Crush System for engineering works. The plasma system complements defects of existing dynamite such as exploding sounds, and fragments of explosion.
