12105A222KAT2A

The 12105A222KAT2A is a multilayer ceramic capacitor (MLCC) manufactured by AVX, representing a reliable passive component solution for general-purpose filtering and signal coupling applications in electronic assemblies. This part belongs to AVX's established capacitor portfolio, designed to meet the needs of industrial and commercial electronics where cost-effectiveness and proven performance are essential. Multilayer ceramic capacitors like this model are fundamental building blocks in modern electronics, serving critical functions including power supply filtering, noise decoupling, signal coupling, and bypassing. They are found extensively in consumer electronics, industrial control equipment, telecommunications infrastructure, automotive systems, and computer peripherals. The MLCC technology offers advantages over alternative capacitor types, including compact size, low equivalent series resistance (ESR), high capacitance density, and proven long-term reliability in high-volume production environments. The 12105A designation indicates this is a 1210 case size capacitor, a standard package dimension widely recognized across the electronics industry. This mid-range package size strikes a practical balance between component density and ease of handling in manufacturing, making it suitable for applications where space efficiency matters but extreme miniaturization is not required. The 1210 format accommodates adequate capacitance values while remaining compatible with standard PCB assembly processes and equipment. The "222K" portion of the part number indicates the capacitance value in the standard three-digit code used for ceramic capacitors, while "AT2A" references AVX's specific dielectric class and rated voltage specification within their product series. AVX's capacitor lines are typically designed for operating conditions common in industrial electronics, with carefully selected dielectric materials and construction methods to ensure stable performance across typical temperature ranges encountered in field deployment. Engineers might select the 12105A222KAT2A specifically when their design requires a combination of proven supplier reliability, established supply chain availability, and performance characteristics that have been validated in similar applications. AVX's long history in capacitor manufacturing means this part number likely represents a mature product with extensive manufacturing history, reducing uncertainty for critical designs. Additionally, the 1210 package provides practical advantages in rework and repair scenarios compared to smaller chip sizes, which can be important for industrial equipment that requires field service support. For applications requiring capacitive filtering or decoupling in standard industrial electronics where performance is predictable and well-documented across the product family, this capacitor represents a straightforward, dependable choice.
