1812GA221JAT1A

The 1812GA221JAT1A is a multilayer ceramic capacitor (MLCC) manufactured by AVX, one of the established producers of passive electronic components. This part belongs to the 1812 package family, which refers to the physical dimensions of the component in metric notation—a rectangular form factor that measures 4.5mm by 3.2mm with a thickness suitable for standard PCB assembly processes. Multilayer ceramic capacitors like this model are fundamental building blocks in modern electronics, used to store and filter electrical energy across a wide range of applications. The 1812 package size represents a mid-range option that balances capacitance capability with practical circuit board real estate, making it popular in applications where space is moderately constrained but higher capacitance values are needed compared to smaller packages. This component would typically be found in industrial control systems, power supply circuits, audio equipment, telecommunications infrastructure, and consumer electronics where voltage filtering, decoupling, or signal coupling functions are required. Engineers often specify capacitors in this package size for applications demanding moderate capacitance values with good frequency response characteristics. The 1812 form factor also provides mechanical robustness suitable for harsh industrial environments where component vibration or thermal cycling is a concern. AVX's 1812 series capacitors are generally recognized for reliable performance in mainstream industrial applications. The specific variant designation suggests this is a capacitor with particular dielectric material and construction chosen for stability across typical operating temperature ranges. Industrial buyers often prefer established manufacturers like AVX for critical applications because of consistent performance, availability of documentation, and proven field reliability data. When comparing alternatives, engineers might choose the 1812GA221JAT1A specifically because it offers the right balance of package size, capacitance value, and electrical performance for their particular circuit requirements. The part number's structure indicates it is part of a larger family with variations in capacitance values and electrical ratings, so availability within an established series makes design flexibility easier. This capacitor would typically be soldered to a PCB using standard surface-mount assembly processes, making it compatible with modern manufacturing workflows. Its reliability and performance characteristics make it suitable for designs requiring long operational life and predictable electrical behavior across varying environmental conditions commonly encountered in industrial settings.
