By Baek Byung-yeul Samsung Electro-Mechanics has developed a new multi-layer ceramic capacitor (MLCC) that is ultra-small and has high capacity, targeting the high-priced IT device market, the IT component arm of Samsung Group said Thursday. An MLCC is a core component of electronic devices, controlling the stable flow of current within electric circuits in smartphones and home appliances. With more cars adopting electronics equipment, MLCCs are also increasingly used in cars. Samsung Electro-Mechanics said it developed the industry's first 0402-size MLCC ― 0.4 millimeters in length and 0.2 millimeters in width ― with 1.9 microfarad capacity and 6.3 voltage. As each IT gadget requires more than 1,000 MLCCs, how small a MLCC can be made shows competitiveness.
