12105D105KAT2A

# AVX 12105D105KAT2A Product Description The AVX 12105D105KAT2A is a multilayer ceramic capacitor (MLCC) designed for general-purpose and industrial electronic applications. As a component from AVX's established capacitor product line, this part is engineered to provide reliable energy storage and signal coupling/decoupling in a compact surface-mount package. Multilayer ceramic capacitors like this one form the backbone of modern electronic circuit design. They are used extensively across industries wherever stable capacitance, small physical footprint, and cost-effectiveness are required. This part is commonly found in power distribution networks, filtering circuits, coupling and decoupling applications, timing circuits, and various analog and digital signal processing stages. Engineers routinely specify MLCCs in consumer electronics, telecommunications equipment, automotive electronics, industrial control systems, and medical devices. The 12105D designation indicates this is a 1210 package size, which represents a standard surface-mount format measuring approximately 12.7mm by 10.2mm. This mid-range package size offers a practical balance between capacitance density and ease of handling during assembly. The "D" in the part number typically indicates a specific dielectric material class, which influences the capacitor's temperature stability, voltage rating, and frequency response characteristics. AVX's D-class ceramics are engineered for applications where moderate temperature stability and good general-purpose performance are needed. The "105" designation suggests a capacitance value in the range typical for this component family, while the "K" indicates a standard tolerance class commonly used in industrial applications. The "AT2A" suffix identifies the specific termination type and manufacturing variant, ensuring compatibility with standard PCB assembly processes. When selecting among alternative capacitors, engineers choose this specific part based on several factors: the proven reliability of AVX's manufacturing, the package size's compatibility with their PCB layout, the performance characteristics of the D-class dielectric for their voltage and temperature requirements, and the cost-effectiveness of this component across production volumes. The standardized package and specifications make this part suitable for both prototype development and high-volume manufacturing scenarios. This component is RoHS-compliant and suitable for use in applications requiring environmental compliance. Its construction using established ceramic technology provides consistent performance over the operational life of the equipment, making it a dependable choice for design engineers and procurement specialists.
