Samyoung Electronics

What Samyoung Electronics does

Samyoung Electronics Co., Ltd. (삼영전자) is a South Korea–based manufacturer of aluminum electrolytic capacitors and conductive polymer aluminum hybrid capacitors, founded in 1968 and headquartered in Seongnam-si, Gyeonggi-do. The company is publicly listed on the Korea Stock Exchange (KOSPI) under ticker 005680 and operates through wholly-owned subsidiaries including Samyoung H.K. Limited (Hong Kong regional office), a Qingdao manufacturing facility, and sales branches in Shanghai, Tianjin, and Shenzhen. Its product portfolio spans four primary form factors — large/PCB-terminal, screw-bolt-terminal, miniature/radial-lead, and SMD — plus a conductive polymer aluminum hybrid series, covering voltage ratings from 4V to 650V, capacitance from 0.1μF to 680,000μF, operating temperatures up to 150°C, and lifespans up to 20,000 hours. The catalog contains more than 100 series serving power electronics, inverter, automotive, and industrial electronics customers.

Samyoung generates revenue through direct B2B sales of capacitors to electronics OEMs, leveraging long-standing OEM qualifications including first-in-Korea IECQ manufacturer recognition (1984), ISO/TS 16949:2009 for automotive, and Green-Partner certifications from Sony (2003), Samsung (2004), and LG Electronics (2006). The go-to-market model is direct enterprise sales, with the Seongnam HQ handling domestic Korean customers and dedicated offices in Hong Kong, Qingdao, Shanghai, Tianjin, and Shenzhen covering Asia-Pacific demand. Recent product development has emphasized higher-temperature, higher-ripple SMD and hybrid series (FSV, FPX, FRW, FQV, FPV, FPW, FRV, UDB) targeting automotive and power-electronics applications. The company also operates a separate materials business (재료사업), pointing to vertical integration into upstream capacitor-grade raw materials. Governance includes a 2024 leadership transition with Byun Dong-joon as Chairman and Kim Seong-su as President.

Core offering

Samyoung Electronics manufactures aluminum electrolytic capacitors and conductive polymer aluminum hybrid capacitors for power management, energy storage, filtering, and smoothing applications. The product portfolio is organized into four primary categories: Large Types (PCB Terminal and Screw-Bolt Terminal) for industrial/inverter use, Miniature Types (Radial Lead), Surface Mount Types (SMD), and Hybrid Series combining liquid electrolyte with conductive polymer technology. The capacitors serve electronics manufacturers across consumer electronics, automotive, industrial equipment, and telecommunications sectors.

Product overview

Samyoung Electronics is a manufacturer of aluminum electrolytic capacitors and conductive polymer aluminum hybrid capacitors. The company offers two main product categories: (1) Aluminum Electrolytic Capacitors including Large Types (PCB Terminal and Screw-Bolt Terminal), Miniature Types (Radial Lead), and Surface Mount Types (SMD); and (2) Conductive Polymer Aluminium Solid Capacitors (Hybrid Series). The product portfolio spans over 100 series with various configurations for applications including general purpose, high reliability, wide temperature, long life, high ripple current, ultra low ESR, and special applications such as air bag, photo flash, welding machines, and inverters. Capacitors range from 4V to 650V voltage ratings and 0.1μF to 680,000μF capacitance with temperature ratings from 85°C to 150°C and lifespans from 1,000 to 20,000 hours.
