Excessive exposure to electromagnetic waves have been reported to cause not only minor symptoms such as drowsiness, insomnia, headache, nausea, staff shoulders, but also serious disorders including skin ailments, feeble pulse, spasm and seizure, sexual dysfunction and dementia.

Keosung Electronics’ newest electromagnetic waves filter marketed under the brand name of “SEPA” is designed with an aim to completely prevent such abnormal symptoms from being generated.

It significantly reduces indoor electromagnetic waves(band ranging 150KHz ~ 30MHz) emitted from electric/electronic products indoors to the level well within the international limit. The electromagnetic waves filter prevents possible occurrence of malfunction of electric/electronic products. It helps extend product life and saves energy by suppressing current and voltage changes.

The product is semi-permanently available without having to replace filters. By just plugging into each EMI filter, operators can easily use it. Weighing 63g, it features 65.5 x 41.5 x 41.5mm in size. Now, such various items as RF module, DC soldering, PCL86 tube integrated amplifier, vacuum fluorescent display clock, etc. are also available for customers.

Suwon-based Keosung Electronics is a company manufacturing such core parts for the telecommunications
industry as crystal units, crystal oscillators, monolithic crystal filters, etc. Such high-quality telecommunication part products are being briskly exported to foreign markets riding on their vigorous local sales performance.
