1812AA202KAT1A

The 1812AA202KAT1A is a multilayer ceramic capacitor (MLCC) manufactured by AVX, designed for general-purpose energy storage and filtering applications across a wide range of electronic systems. This component belongs to the 1812 package family, which uses a surface-mount form factor measuring 1812 in imperial notation (approximately 4.5mm x 3.2mm), making it suitable for high-density circuit board layouts common in modern industrial and consumer electronics. Multilayer ceramic capacitors like this part are fundamental passive components used to store electrical charge and smooth voltage fluctuations in power distribution networks. The 1812 package size represents a mid-range option that balances capacitance value, voltage handling capability, and physical footprint—making it popular in applications where board space is moderately constrained but higher capacitance values are required compared to smaller packages. AVX's MLCC products are widely specified in automotive electronics, industrial control systems, telecommunications infrastructure, medical devices, and power management circuits. The 1812AA series typically serves roles including bulk capacitance in power supply decoupling, AC coupling and signal filtering, timing circuits, and energy storage in switching power supplies. Engineers often choose MLCCs from established manufacturers like AVX for their consistency, reliability data, and availability across global supply chains. When selecting the 1812AA202KAT1A specifically, engineers benefit from AVX's manufacturing quality standards and the proven performance history of this package family. The part number designation indicates this is a standard variant within AVX's commercial product line, designed to meet typical industrial operating conditions. Compared to alternatives, MLCCs offer advantages including low equivalent series resistance (ESR), minimal temperature drift in controlled designs, and cost-effectiveness at volume. The 1812 package provides more capacitance than smaller packages (0603, 0805) while remaining more practical than larger ceramic packages for most circuit applications. Industries selecting this component typically require reliable bulk capacitance solutions that can withstand the thermal cycling and vibration stresses common in manufacturing environments, automotive systems, and outdoor installations. The multilayer construction provides stability across repeated charge-discharge cycles, making MLCCs particularly valuable in power conversion and regulation circuits where consistent performance over product lifetime is critical. For engineers evaluating this part, working with detailed component specifications, application notes, and compatibility verification with your specific circuit requirements is recommended to ensure optimal performance within your intended design.
