12105A222FAT2A

# Product Description The AVX 12105A222FAT2A is a multilayer ceramic capacitor (MLCC) designed for general-purpose energy storage and filtering applications in electronic equipment. This component is part of AVX's established capacitor lineup, serving as a reliable solution for engineers who require stable capacitive performance across a range of industrial and commercial applications. Multilayer ceramic capacitors are among the most widely used passive components in modern electronics. They function by storing electrical energy in an electric field between multiple internal ceramic layers, making them essential for power supply filtering, signal coupling and decoupling, noise suppression, and frequency compensation circuits. The 12105A222FAT2A is engineered to deliver consistent performance in these roles. The part number designation indicates this capacitor uses a 1210 case size (metric dimensions approximately 3.2mm × 2.5mm), which is a standard SMD (surface-mount device) footprint. This compact package allows for space-efficient circuit board layouts while maintaining adequate capacitive performance. The surface-mount format makes this component suitable for automated assembly processes, reducing manufacturing costs and improving production reliability for high-volume applications. The "222" in the part number refers to the capacitive value, following standard electronics coding conventions. This mid-range capacitance value makes the part suitable for general filtering and decoupling applications where engineers need neither extremely small nor very large capacitance values. Engineers commonly specify this capacitor in power distribution networks, where it helps maintain stable voltage levels and reduces transient voltage spikes that could damage sensitive circuitry. AVX capacitors are known for consistent manufacturing quality and reliable performance across temperature variations and operational stress conditions. Engineers often select specific part numbers from AVX's catalog when they require predictable behavior over the product's lifetime, particularly in industrial equipment where component failure can result in costly downtime. The 12105A222FAT2A is typically considered a mainstream component suitable for general-purpose industrial applications rather than specialized high-performance environments. It represents a cost-effective choice for applications where standard ceramic capacitor characteristics meet the design requirements. Engineers working on consumer electronics, industrial control systems, telecommunications equipment, and other standard applications frequently incorporate this type of component into their designs. Selecting this exact part number ensures compatibility with existing board designs and manufacturing processes already validated for this specific package and performance class.
