A Leading Manufacturer of Electrolytic Capacitors Drawing Attention in the Global Electronics Market
[INQ. NO. 2210E14] Samwha Electric Co., Ltd., a specialty manufacturer of electrolytic capacitors in Korea, is attracting in the global electronics market by launching a conductive polymer hybrid electrolytic capacitor built with advanced technology.
Samwha Electric has been providing the global market with its electric double-layer capacitor, ‘Green-Cap,’ used for eco-friendly high-value added products, such as 5G, eco-friendly vehicles, medical devices, LED, robots, Internet-of-Things (IoT), and energystorage systems (ESSs) for wind and solar power for many years.
Thanks to a long replacement cycle based on fast charge/discharge cycles for over one 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 are growing worldwide.
Through its five sales subsidiaries in Germany, the United States, China, Thailand, and India, as well as through 14 major regional offices in other countries, the company has built a stable international business infrastructure to lead the global market.
Expecting a brighter future in line with expansion in eco-friendly automotive infrastructure and increase in demand for eco-friendly power due to stricter 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),” explained a manager at Samwha Electric.
The current key products of the company are: EDLC (Electric Double Layer Capacitor) for radial, snap-in, axial type & module; conductive polymer hybrid aluminum electrolytic capacitor for radial, SMD type; and aluminum electrolytic capacitor for radial, SMD, snap-in, lug, screw type.
Samwha Electric’s electrolytic capacitors are selected to be used in household appliances for high ripple current, miniaturization and long fife.
The products are popular in solar power inverters for high voltage, high-capacitance and high ripple current. The field of power electronics is among their applications – for high capacitance, high ripple current and long life and power industry, plant business, and infrastructure business sector.
They are popular as LED lighting products for ultra-high temperature, long life and low impedance. They are also applied in automotives for powertrain (ECU, DC/DC converter), safety (breaking, airbag, ABS) and exterior (LED headlight).

This product has intermediate characteristics between an Al capacitor and a secondary battery. Eco-friendly material is used, reducing risk of fire and explosion, thereby incurring no problems even if is damaged due to impact. It has the advantage of operating for a certain time even though the element is exposed due to problems occurring outside of the product compared with the secondary cell which is immediately heated or explodes. Its ordinary rated voltage is 2.5V or 2.7V. As it has a very long service life, the product can be used for one thousand hours at the maximum operating temperature of 70˚C. It also can be charged/discharged even at low temperature. Its cycle life is over 500,000 cycles, which is very long compared to existing rechargeable batteries.
