18123C104MAT2A

The AVX 18123C104MAT2A is a multilayer ceramic capacitor (MLCC) designed for general-purpose energy storage and filtering applications in electronic circuits. This component belongs to the broad family of ceramic capacitors, which are among the most widely used passive components in modern electronics due to their compact size, reliability, and cost-effectiveness. Multilayer ceramic capacitors like this part are constructed from multiple layers of ceramic dielectric material interleaved with metal electrodes, which are then stacked and sintered together. This construction method allows manufacturers to achieve substantial capacitance values in remarkably small physical packages. The "18123" designation indicates this is a surface-mount component in a standardized package size, making it suitable for automated assembly on printed circuit boards alongside other modern electronic components. The "C" designation in the part number identifies the capacitance value within AVX's naming scheme, though the exact value can be confirmed through the full part number documentation. This particular variant is commonly found in applications requiring stable performance across standard industrial temperature ranges and voltage ratings typical of general-purpose filtering and energy storage roles. Engineers specify AVX multilayer ceramic capacitors in a wide range of applications including power supply circuits, signal coupling and decoupling, noise filtering, timing circuits, and RF applications. In power supplies, these capacitors help reduce voltage ripple and smooth output. In digital circuits, they serve as decoupling capacitors placed close to integrated circuit power pins to supply transient current demands and minimize noise. They are also used extensively in analog signal processing, audio equipment, telecommunications infrastructure, automotive electronics, and industrial control systems. The appeal of this particular part lies in AVX's manufacturing reputation for consistency and reliability combined with the inherent advantages of the MLCC technology. Compared to alternatives such as electrolytic or tantalum capacitors, MLCCs offer superior frequency response, longer operational life without degradation, and better tolerance stability over time. They require no polarity during installation, simplifying circuit board design and assembly. For engineers working on products requiring high reliability or operating in temperature-stable environments, this component represents a proven choice. This capacitor is well-suited for OEM manufacturers, contract electronics assemblers, and engineering teams designing consumer, industrial, medical, and telecommunications equipment where proven, cost-effective energy storage and filtering performance is essential.
