2220AA471JAT1A

The 2220AA471JAT1A is a multilayer ceramic capacitor (MLCC) manufactured by AVX, designed for general-purpose energy storage and filtering applications in electronic circuits. This component belongs to the 2220 case size family, which represents a larger capacitor format that provides higher capacitance values compared to smaller packages while maintaining a relatively compact footprint suitable for modern PCB designs. Multilayer ceramic capacitors are among the most widely used passive components in electronics manufacturing. They function by storing electrical energy in an electric field between conductive plates separated by ceramic dielectric material. This fundamental design makes them essential for smoothing power supply voltages, filtering high-frequency noise, decoupling integrated circuits, and supporting timing circuits across industrial and consumer applications. The 2220 package size is particularly popular in industrial control systems, telecommunications equipment, automotive electronics, power management modules, and test and measurement instruments. Engineers often select this larger case format when circuit designs require higher capacitance values without resorting to electrolytic capacitors, or when the application benefits from the reliability and temperature stability characteristics of ceramic technology. The 2220 footprint also offers practical manufacturing advantages, including better visibility for visual inspection and easier handling during assembly processes. AVX ceramic capacitors in this family are recognized for consistent performance in demanding industrial environments. The 2220 case provides a substantial amount of capacitive material, which typically results in stable performance across temperature variations—a critical consideration in applications subject to thermal cycling or extreme operating conditions. These capacitors generally maintain their electrical properties across a wide frequency range, making them suitable for both DC applications and AC filtering tasks. When selecting the 2220AA471JAT1A specifically, engineers value the combination of physical size, proven manufacturing quality, and the compatibility with standard PCB assembly equipment. Compared to smaller case sizes, the 2220 format can deliver required capacitance values with lower per-unit stress on the dielectric material, potentially contributing to improved long-term reliability in mission-critical applications. This part number's designation indicates it belongs to AVX's established ceramic capacitor portfolio, offering design engineers a trusted option for applications where component reliability, temperature performance, and consistent electrical behavior are important selection criteria. It represents a practical choice for both prototype development and high-volume industrial production.
