0805YA821KAT2A

The 0805YA821KAT2A is a multilayer ceramic capacitor (MLCC) manufactured by AVX, featuring the widely-used 0805 surface-mount package format. This component is designed for general-purpose energy storage, filtering, and decoupling applications in electronic circuits where space efficiency and reliability are important considerations. Multilayer ceramic capacitors represent one of the most common passive component types in modern electronics. The 0805 package size offers a practical balance between component density and ease of assembly, making it suitable for both consumer and industrial-grade applications. These capacitors are constructed from alternating layers of ceramic dielectric material and metal electrodes, enabling high capacitance values in a compact form factor. The "YA" designation in this part number indicates this capacitor belongs to AVX's established MLCC family, which is engineered for stable performance across standard operating temperature ranges. Components in this category are typically specified in applications requiring temperature stability and long-term reliability. The 821 character sequence in the part number encodes the capacitance value using standard EIA coding conventions. Engineers commonly specify 0805 MLCCs in power supply filtering circuits, signal coupling and decoupling networks, and various RF and analog applications. These capacitors are particularly prevalent in circuit board designs where PCB real estate is constrained, as the 0805 package provides significantly smaller footprint compared to larger packages while maintaining adequate capacitance and voltage ratings for many applications. AVX's MLCC components are known for consistent dielectric performance and manufacturing quality across high-volume production runs. The ceramic formulation used in these capacitors typically supports operation across industrial temperature ranges, making them suitable for equipment designed to function in demanding environments. This consistent performance characteristic makes 0805 MLCCs from established manufacturers like AVX a preferred choice for engineers designing products requiring high reliability and predictable long-term behavior. When selecting a specific MLCC part number like the 0805YA821KAT2A, engineers typically consider the required capacitance value, voltage rating, temperature coefficient of capacitance, and the physical constraints of their PCB layout. The 0805 package remains an industry standard due to its widespread availability, mature manufacturing processes, and compatibility with modern automated assembly equipment. Whether used in consumer electronics, industrial control systems, telecommunications equipment, or automotive applications, 0805 multilayer ceramic capacitors continue to serve as fundamental building blocks in circuit design. This particular AVX component represents a reliable choice for applications demanding proven performance in a compact surface-mount format.
