Electrolytic Capacitors


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).

https://korean-electronics.com//inquiry[INQ. NO. 1912E43] SAMWHA ELECTRIC Co., Ltd. is focusing on R&D and marketing power to become one of the best digital companies in the 21st century. The company is continuously developing products and solutions that enable more efficient use of energy to meet the needs of customers in the global market.
SAMWHA ELECTRIC is a company that produces electrolytic capacitors used mainly for home appliances as they have large capacity despite their small sizes. The company has been manufacturing various electrolytic capacitors including radial, SMD, snap-in and screw types and is supplying them to its main customers such as LG Electronics, Samsung Electronics and 35 other overseas electricity and electronics companies.
In particular, the company has completed the development of “conductive polymer hybrid electrolytic capacitors” and “electric double layer capacitors,” all of which are used in a wide range of fields including information, 5G communication, hybrid vehicles, wind/solar power and other new renewable energy and power-generating equipment in line with the recent increase in the demand for eco-friendly and high value products.
“Considering the features (charging and discharging in a short period of time) of electrolytic capacitors, they are mostly used for home appliances. However, the company is expanding its business areas and developing products to respond to next-generation markets such as 5G communication, vehicles, wind power, solar power, ESS, robots and IoT,” explained a spokesperson for the company.
Meanwhile, the company is systemically controlling the quality of its products based on a three-step management system in order to grow itself into a general electronic components maker. And, it is also efficiently managing the manufacturing processes through an Enterprise Resource Planning (ERP) system and a real-time Manufacturing Execution System (MES).
The company plans to develop itself into a leading electronic compoment manufacturer in the era of fierce competition through its own technology and R&D for the future industry, centering on the R&D center in its HQs.

https://korean-electronics.com//inquiryVinatech Co., Ltd. started as an electronic components trading company specializing in tantalum capacitors and, later in 2004, it expanded its business to manufacturing super capacitors, an eco-friendly energy storage device that the company had been aiming for.
Based on its technical capacities built so far, the company is committed to developing new products and technologies to be the world’s best quality and an excellent service provider.


Supercapacitor (EDLC, P-EDLC)

Compared with battery, Supercapacitor has one-tenth of energy, but delivers over 10 times power due to ultra low ESR. It operates more reliably in wider temperature range and its life is semi-permanent, over 500,000 cycles. This product has characteristics of higher power density (low ESR) and over 500,000 cycle life (semi-permanent). This product is used in a need of short-term peak power assistance.



Lithium Ion Capacitor (LIC)

This is an extremely low self-discharge of a lithium ion capacitor, even in high heat environments, ensuring a longlasting charge.
This delivers higher energy density (double that of EDLC), guaranteeing over 100,000 cycle life.
This product has characteristics of low self discharge and low leakage current & long-term backup applications.



Fuel Cell Material (Supporter, Catalyst, MEA) & Carbon Filter

Vinatech develops and sells carbon applied components such as supporter, catalyst & MEA for fuel cell and carbon filter. Among the features of these products are: fibrous carbon & spherical; high electrical conductivity by high crystallization; high anti-corrosion; catalyst on edge.
Vinatech aims to accomplish the VINA mission of “Providing eco-friendly products and contribute to the building of a harmonious society through the happiness of our members.” Toward this end, Vinatech will strive to realize our goal to become the leading company in the relevant industries and create more valuable jobs.
