Reading time ( words)

SAMWHA ELECTRIC, a leading manufacturer specialized in electrolytic capacitors in Korea, draws attention in the world electronics market by launching a conductive polymer hybrid electrolytic capacitor leveraging advanced technology to cope with increasing demand for electronic components used for smart city industry, a future strategic market.

SAMWHA ELECTRIC has been providing the global market with its electric double layer capacitor ‘Green-Cap’ used for eco-friendly high-valued products, such as 5G, eco-friendly vehicles, medical devices, LED, robots, Internet-of-Things (IoT), and energy storage systems (ESSs) for wind and solar power for many years.

Thanks to a long replacement cycle based on fast charge/discharge cycles for over 1 million times, Green-Cap is easy to maintain and it can be used in extreme temperatures. As it does not contain environmentally hazardous substances, it is also easy to treat after use.

With increasing demand in strategic markets including electric vehicles, communication, smart consumer electronics, renewable energies, UPS, automotive industry and electronic components, orders for the product is growing worldwide. Through its five sales subsidiaries in Germany, the United States, China, Thailand and India as well as 14 major regional offices in other countries, the company has built stable international business infrastructure to lead the global market.

Expecting brighter future in line with expansion in eco-friendly automotive infrastructure and increase in demand for eco-friendly power due to expanded environment regulation policies, SAMWHA ELECTRIC aims to meet demands for high-specification products by developing high-valued devices at its corporate R&D center and to take an advantageous position while transforming into a leading electronic component company by developing proprietary technologies.

“In order to grow into an integrated electronic parts maker through systematic quality control, we are implementing management systems in three stages, and effectively managing production processes with enterprise resource planning (ERP), a real-time data management system, and manufacturing execution system (MES),” said a manager at SAMWHA ELECTRIC.

Backed by these efforts, SAMWHA ELECTRIC is further advancing into the global market with synergies of designation as one of beneficiaries of support program of the Korea Trade-Investment Promotion Agency (KOTRA). The company also values shared growth with affiliates by establishing partnership relations. The corporate culture of SAMWHA ELECTRIC that shares values with clients has potential for further development with their trust.
