1812HA470KAT1A

The 1812HA470KAT1A 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 1812 case size family, which is a surface-mount package measuring approximately 4.5mm × 3.2mm. The "HA" designation within AVX's product line indicates this capacitor is formulated for standard commercial applications where moderate voltage and temperature stability are required. Multilayer ceramic capacitors like this part are among the most widely used passive components in modern electronics due to their compact size, cost-effectiveness, and reliable performance across a broad range of operating conditions. The 1812 package size represents a popular midrange option that balances capacitance density with ease of assembly on standard surface-mount manufacturing equipment. This capacitor is commonly specified in filtering circuits, decoupling applications, and energy storage stages within power supplies, audio equipment, telecommunications infrastructure, industrial control systems, and consumer electronics. Engineers select 1812 case capacitors when they need more capacitance than smaller packages can provide, but don't require the space occupied by larger discrete components or electrolytic alternatives. The multilayer ceramic construction of this component offers several advantages relevant to industrial and engineering applications. MLCCs provide excellent high-frequency performance, stable behavior across temperature ranges typical of industrial environments, and inherently lower equivalent series resistance (ESR) compared to electrolytic capacitors. This makes them particularly valuable in switching power supplies, RF filtering circuits, and applications where reliability and long operational life are critical. AVX's 1812HA series capacitors are manufactured to commercial-grade standards, making them suitable for general industrial use while remaining cost-competitive for high-volume production. These components are RoHS compliant and lead-free, meeting regulatory requirements for modern electronics manufacturing in most markets. Engineers typically specify the exact 1812HA470KAT1A part number when their circuit design calls for the specific capacitance value indicated by this component's designation, combined with the electrical characteristics and temperature stability of AVX's HA formulation and the proven manufacturing reliability of this particular series. The 1812 package also provides a practical balance between component density on the PCB and handling compatibility with standard pick-and-place assembly equipment, making it economical for both prototype and production environments.
