0805YC821KAT2A

The 0805YC821KAT2A is a multilayer ceramic capacitor (MLCC) manufactured by AVX, one of the world's leading capacitor suppliers. This component belongs to the 0805 package family, which is one of the most widely adopted surface-mount sizes in modern electronics manufacturing. The 0805 designation refers to imperial dimensions of 0.080 inches by 0.050 inches, making these capacitors compact enough for dense circuit boards while remaining straightforward to assemble using standard pick-and-place equipment. Multilayer ceramic capacitors like this model serve as essential building blocks in virtually every electronic device produced today. They function as energy storage elements, noise filters, and signal coupling components across countless applications. The 0805 package strikes an ideal balance between physical size and performance capability, which explains its prevalence in consumer electronics, industrial control systems, telecommunications equipment, automotive modules, and medical devices. The "Y" designation in this part number indicates the temperature coefficient classification, which means this capacitor maintains relatively stable capacitance across a defined temperature operating range. This stability is critical in circuits where capacitance drift could compromise performance or reliability. The ceramic dielectric material used in these capacitors provides good volumetric efficiency, allowing manufacturers to achieve substantial capacitance values in compact packages. AVX's 0805 ceramic capacitors are engineered for high-reliability applications and typically feature excellent frequency response characteristics. These components handle the demands of modern high-speed circuits, from DC blocking and power supply bypassing to RF and analog signal conditioning. The robust construction and proven design make them suitable for both commercial and industrial-grade applications where long-term dependability matters. Engineers often specify this exact part number when their designs require a proven, readily available component with established manufacturing consistency. The 0805 format offers significant advantages over smaller packages in terms of handling during assembly and rework, while offering more space efficiency than larger alternatives. AVX's reputation for quality and their extensive product validation across industries make their capacitors a standard choice for designers who prioritize supply chain reliability alongside performance. Whether you're designing new equipment or maintaining critical industrial systems, 0805 ceramic capacitors remain the go-to solution for decoupling, filtering, and energy storage needs where size, cost, and dependability converge.
