12105C105KAJ2A

The 12105C105KAJ2A is a multilayer ceramic capacitor (MLCC) manufactured by AVX, one of the leading producers of passive electronic components. This is a fixed-value capacitor designed for use in a wide range of industrial, commercial, and consumer electronics applications where stable capacitance and reliable performance are required. Multilayer ceramic capacitors like this part are among the most widely used passive components in modern electronics. They function by storing electrical charge between multiple layers of ceramic dielectric material and metal electrodes, making them essential for filtering, decoupling, energy storage, and signal coupling in circuits. Their compact size, low cost, and excellent reliability make them the standard choice across most electronic designs. The part number indicates this is from AVX's general-purpose MLCC family. The "C" designation typically indicates it belongs to their standard multilayer ceramic product line. These capacitors are constructed with alternating layers of ceramic material and conductive electrodes, all encapsulated in a robust epoxy or ceramic outer case. The specific package type for this part number suggests it uses a standard surface-mount footprint compatible with automated assembly processes. Engineers typically specify AVX multilayer ceramic capacitors for applications requiring proven reliability and consistent performance in cost-sensitive designs. These capacitors are found in power supply circuits, audio equipment, RF circuits, telecommunications infrastructure, industrial control systems, automotive electronics, and computing equipment. They excel in applications requiring rapid charge and discharge cycles, making them particularly valuable in switching power supplies and high-frequency circuits. What distinguishes this particular part number among alternatives is the combination of its capacitance value and voltage rating paired with AVX's manufacturing quality standards. AVX capacitors are known for tight tolerance ranges, stable performance across temperature variations, and low equivalent series resistance (ESR) characteristics relative to their size. The specific part number encodes both the electrical characteristics and the physical package, meaning engineers selecting this exact part are ensuring compatibility with their PCB layout and assembly specifications. Industrial and engineering buyers choose this component when they need confidence in supply chain stability and consistent electrical performance across production batches. AVX's reputation for quality control makes this part suitable for applications where capacitor failure could cause equipment downtime or require costly rework.
