CL03A104MA3NNNC

The CL03A104MA3NNNC is a multilayer ceramic capacitor (MLCC) manufactured by Samsung, representing a key passive component found in countless modern electronic applications. This particular part belongs to Samsung's established line of general-purpose ceramic capacitors, which are fundamental building blocks in circuit design across industrial, consumer, and communications equipment. Multilayer ceramic capacitors like this component are used primarily for energy storage, filtering, decoupling, and signal coupling in electronic circuits. They appear in power supply designs, audio equipment, RF circuits, medical devices, automotive electronics, and industrial control systems. Their compact size, reliability, and cost-effectiveness make them the standard choice for applications where space is limited and performance must remain stable across varying environmental conditions. The designation "CL03A" in the part number indicates this is a surface-mount ceramic capacitor in a 0402 package size (0.04 by 0.02 inches), one of the most widely used formats in modern PCB assembly. The 0402 package offers a balance between miniaturization and ease of handling during manufacturing, making it ideal for high-density circuit boards while remaining compatible with standard pick-and-place equipment found in contract manufacturing facilities. The "104" in the part number refers to the capacitance value using standard three-digit notation, indicating a 0.1 microfarad (100 nanofarad) capacitor. This capacitance range is extremely common in decoupling and filtering applications, particularly for power supply filtering near integrated circuits and for AC signal coupling in audio and RF circuits. The "MA" designation suggests this capacitor operates at a standard voltage rating typically found in general-purpose applications. Engineers specify this exact part number for several practical reasons. First, the 0.1 microfarad value is the most frequently used capacitance in modern electronics, appearing in nearly every digital circuit design. Second, Samsung's CL series is known for consistent quality, long-term availability, and broad design-in acceptance across industries. Third, the 0402 package size allows designers to maintain compact PCB layouts without requiring specialized assembly equipment. Finally, the wide availability and multiple sourcing options make this part economical for both prototype development and high-volume production runs. This component represents the practical, no-nonsense choice for engineers who need reliable capacitive filtering and energy storage without paying a premium for specialized performance characteristics. Its ubiquity in electronics means that most design teams have extensive experience with this part family, reducing design risk and qualification time.
