1812CC221KAT1A

The 1812CC221KAT1A is a multilayer ceramic capacitor (MLCC) manufactured by AVX, representing a reliable component widely used in electronic circuit design and assembly. This capacitor belongs to the 1812 package family, which refers to its physical dimensions in metric notation (approximately 4.5mm x 3.2mm), making it a mid-sized surface-mount component suitable for modern PCB layouts where space efficiency matters but component density isn't at maximum levels. Multilayer ceramic capacitors like this model serve as fundamental building blocks in electronic circuits, functioning primarily to store and release electrical energy, filter signals, and decouple power supplies. The ceramic dielectric material composition determines the capacitor's electrical behavior, stability, and suitability for specific applications. This part number indicates a general-purpose ceramic capacitor configuration commonly employed across numerous industries. The 1812 package format offers practical advantages in manufacturing and assembly. Its size provides adequate capacitance capability while maintaining reasonable cost efficiency compared to larger packages, and it's substantial enough to handle common circuit requirements without requiring specialized handling equipment. The surface-mount design integrates seamlessly with automated assembly processes used in high-volume production environments. Engineers typically specify AVX ceramic capacitors in this package for applications including power supply filtering, signal coupling and decoupling, noise suppression, and timing circuits. Common use cases span consumer electronics, industrial control systems, telecommunications equipment, automotive electronics, and computing devices. The reliability and consistency of AVX components make them suitable for applications demanding predictable performance across production runs. When selecting between capacitor alternatives, engineers consider several factors beyond basic capacitance value: package size constraints on the PCB, voltage rating requirements for the specific circuit node, temperature stability characteristics needed for the operating environment, and cost-performance optimization. The 1812 package represents a middle ground in the capacitor size spectrum, offering a balance that suits many mainstream applications without overspecification. AVX's manufacturing standards ensure consistent quality and performance characteristics across production batches, which is particularly important for industrial and professional applications where component reliability directly impacts system performance. The 1812CC series represents a proven platform with established performance history in field applications. For engineers designing circuits requiring a mid-sized ceramic capacitor with general-purpose characteristics and proven reliability, the 1812CC221KAT1A provides a straightforward specification choice backed by a reputable manufacturer's quality standards.
