The company plays the role of an "upstream component supplier" in the global electronics supply chain, with products widely used in mobile terminals, data center servers, automotive electronics, and network equipment.
Samsung Electro-Mechanics is listed on the Korean stock market as Samsung Electro-Mechanics Co., Ltd., trading under the code 009150.KS on the Korea Composite Stock Price Index (KOSPI). Unlike consumer-facing terminal brands, the value proposition of Samsung Electro-Mechanics is built on component technology, production scale, and downstream industry demand, rather than individual product retail performance.
Company History and Development Milestones
Founded in 1973, Samsung Electro-Mechanics initially began with the production of audio and video electronic components, laying the technical foundation for Korea's component industry. During the 1980s, it expanded into materials and computer components; in the 1990s, it focused on developing chip components, mobile communication components, and optical components. From the 2000s onward, with MLCC, power inductors, camera modules, and packaging substrates as core offerings, it established a global component supply capability.
In 1987, the company changed its name from Samsung Electronic Parts to Samsung Electro-Mechanics. Subsequently, it continuously expanded its product portfolio into high-value-added applications such as automotive electronics and AI servers, strengthening investments in underlying technologies including materials, radio frequency, and precision mechanics. The company's development path reflects an evolution from single-component manufacturing to a multi-technology integrated comprehensive component supplier.

MLCC and FC-BGA: Core Technology Roles
Multilayer ceramic capacitors (MLCC) are one of the core products of Samsung Electro-Mechanics' Components business. MLCC performs energy storage, filtering, and voltage stabilization in circuits, earning it the nickname "the rice of the electronics industry" due to its widespread use in electronic devices. The MLCC component business, from technical principles and application scenarios to global competitive dynamics, serves as a key entry point for understanding Samsung Electro-Mechanics' passive component sector. Rising demand for high-capacity, high-temperature MLCCs from AI servers and automotive electronics is driving the product toward more advanced specifications.
Flip-chip ball grid array packaging substrates (FC-BGA) are a key product in the Package Solutions business. FC-BGA enables high-density interconnection between high-performance chips and motherboards, making it suitable for AI accelerators, server CPUs/GPUs, and automotive autonomous driving chips. FC-BGA requires high technical barriers, with production capacity and process precision forming the core competitive dimensions in the industry.
MLCC and FC-BGA correspond to the two technology tracks of "passive components" and "advanced packaging substrates," respectively, constituting Samsung Electro-Mechanics' structural product positioning amid the expansion of AI infrastructure and automotive electronics demand.
Korean Stock Listing and Trading Basics
Samsung Electro-Mechanics is listed on the KOSPI market of the Korea Exchange (KRX) under stock code 009150.KS. Korean stocks are denominated in South Korean Won (KRW), trade under KRX market rules, and follow the market's trading hours and price fluctuation limits.
In the code 009150, "009150" is the security identifier, while ".KS" denotes the KOSPI market. International investors trading Korean stocks must understand the account opening, settlement, and foreign exchange mechanisms of the Korean market. For users participating in Korean stock-related products via platforms like Gate, the process for buying Samsung Electro-Mechanics stock through Gate's Korean stock trading differs in mechanism from opening a direct Korean securities account. As a KOSPI constituent, Samsung Electro-Mechanics' liquidity and information disclosure follow the regulatory framework for Korean listed companies.
