Samsung Electro-Mechanics

Electronic Components

Samsung Electro-Mechanics began as the component arm of the Samsung empire — the division that made the parts Samsung's own phones, TVs, and cars needed, without having to win any outside customer. That captive start could have kept it small. Instead, SEMCO grew into the world's second-largest maker of multilayer ceramic capacitors (MLCCs), the tiny components that regulate electrical current in virtually every electronic device. The company's crown jewel is its MLCC business: it produces billions of capacitors a month, competing head-to-head with Japan's Murata, and its high-capacity MLCCs are qualified into flagship smartphones and automotive electronics. Beyond capacitors, SEMCO makes camera modules (including the folded zoom modules used in premium phones), semiconductor substrates, and electronic component packages for 5G modules. Based in Suwon, South Korea, with about 27,000 employees and annual revenue near US$7 billion, SEMCO has deliberately reduced its dependence on Samsung: over half its sales now go to outside customers, including Apple and major automakers. For electronics buyers, SEMCO is the classic 'second source' — Murata's closest rival in quality and capacity, and the main alternative when supply tightens.

Samsung Electronics Co., Ltd.

Semiconductors

Samsung Electronics is the improbable triumph of a company that began in 1938 as a trading house selling dried fish, noodles, and produce — and whose founder, Lee Byung-chul, pivoted into electronics in 1969, decades after the chaebol's grocery origins. The bet was staggering: in the 1970s, Samsung started making black-and-white TVs in a country most of the world considered a poor backwater. Fifty years later, it is the world's largest maker of smartphones, memory chips, and TVs. The empire's core is semiconductors: Samsung is the world's largest memory chip maker (DRAM and NAND), with a near-duopoly over advanced memory alongside SK Hynix, and its foundry business makes chips for other companies. Its mobile division's Galaxy line competes head-to-head with Apple for the global smartphone crown, and its consumer electronics division dominates TVs and home appliances. The company also runs one of the world's largest smartphone factories and the largest semiconductor fabs, in Pyeongtaek. Headquartered in Suwon, South Korea, with about 270,000 employees and annual revenue near US$200 billion, Samsung Electronics is the flagship of the Samsung Group, which generates about a fifth of South Korea's GDP. Its challenges — memory price cycles, catching TSMC in leading-edge foundry, and Chinese competition — are the challenges of Korea itself, but its dominance in memory remains the bedrock of the digital world.

LG Electronics Inc.

Consumer Electronics

LG Electronics started in 1958 as GoldStar, making the first radios produced in Korea, and spent its first decades as a scrappy manufacturer of appliances for a recovering nation. Today it is a global consumer electronics and appliance giant — but its most telling transformation is in display: LG is the world's leading maker of OLED TV panels, the technology it bet the television business on when rivals stuck with LCD. The company's portfolio spans four pillars: home entertainment (OLED and QNED TVs), home appliances (washers, refrigerators, and the InstaView and Objet lines), vehicle components (in-vehicle infotainment and EV powertrains), and B2B solutions (commercial displays and HVAC). Its appliance business is a consistent global #1 or #2 in most categories, and its vehicle-solutions division is now a top-tier supplier to automakers worldwide. Headquartered in Seoul with about 74,000 employees and annual revenue near ₩84 trillion (US$62 billion), LG is also unusual for a consumer company: it manufactures the vast majority of what it sells in its own factories — compressors, motors, panels, and electronics — giving it a vertical integration most rivals outsource away.
