12103C472JAT2A

The 12103C472JAT2A is a multilayer ceramic capacitor (MLCC) manufactured by AVX, a recognized leader in capacitor technology. This component belongs to the 1210 package family, which uses imperial notation to denote its physical dimensions. MLLCs of this size are widely used across industrial electronics, telecommunications equipment, power supplies, and consumer electronics where moderate capacitance values and stable performance are required. As a ceramic capacitor, this component stores electrical energy in an electric field created between conductive plates separated by a ceramic dielectric material. The multilayer construction allows manufacturers to achieve useful capacitance values in a compact form factor, making it ideal for space-constrained PCB designs. The 1210 package represents a mid-range size offering a practical balance between capacitance density and ease of handling in automated assembly processes. The part number designation "472" indicates the capacitance value using standard three-digit marking conventions common in the electronics industry. Capacitors in this family typically serve filtering, decoupling, and energy storage functions in circuit designs. They are frequently specified for smoothing voltage ripple in power distribution networks, bypassing high-frequency noise near integrated circuits, and providing localized energy storage in switching power supplies. AVX's MLCC products in the 1210 package are engineered for reliability in demanding industrial environments. These components generally offer stable performance across operating temperature ranges and maintain consistent electrical characteristics under various circuit conditions. The ceramic dielectric material provides predictable behavior and low equivalent series resistance (ESR), which is particularly valuable in modern high-frequency applications. Engineers typically specify this exact part when they require a proven, established component with known procurement and performance characteristics. The 1210 package offers sufficient capacitance for many filtering applications without consuming excessive board space, and its standardized dimensions ensure compatibility with common PCB assembly equipment. AVX's reputation for quality and consistency makes this part a dependable choice for applications where component reliability directly impacts system performance. This capacitor would be selected for production designs where proven component availability, established supply chains, and predictable performance are essential. Whether used in industrial control systems, test equipment, or telecommunications infrastructure, MLLCs of this type provide the fundamental energy storage and filtering functions that modern electronics depend upon.
