08053C821KAT2A

The AVX 08053C821KAT2A is a multilayer ceramic capacitor (MLCC) in the 0805 surface-mount package, designed for general-purpose filtering, decoupling, and bypassing applications across a wide range of electronic equipment. This component represents a common building block in modern circuit design, offering the compact form factor and reliable performance characteristics that industrial and commercial applications demand. Multilayer ceramic capacitors are among the most widely used passive components in electronics manufacturing. The 0805 package—measuring approximately 2.0mm by 1.25mm—strikes a practical balance between size efficiency and ease of handling during automated assembly. This package format is standard across consumer, industrial, and aerospace-grade electronics, making it a versatile choice for designers who need to minimize board space without sacrificing component availability or manufacturability. The "C821" designation in this part number indicates a specific capacitance value within AVX's standard product family. MLCCs in this general range are typically applied in power supply filtering, signal conditioning, and high-frequency decoupling roles. Engineers commonly specify ceramics of this type on power rails, analog signal paths, and mixed-signal circuit nodes where stable, predictable capacitive behavior is essential. Their low equivalent series resistance (ESR) and inductance (ESL) make them suitable for both low and moderate frequency applications. AVX is a well-established manufacturer of capacitive components with a strong presence in industrial and defense sectors. Their MLCC product lines are known for consistent performance and traceability, which appeals to engineers working on regulated or mission-critical systems where component genealogy and reliability documentation matter. The company's manufacturing processes and quality certifications align with the standards expected in automotive, telecommunications, and industrial control markets. Selecting the 08053C821KAT2A over alternative capacitor technologies or values typically comes down to specific circuit requirements: the known dielectric properties of ceramic materials, the precise capacitance value needed for impedance matching or filtering, the thermal and frequency response characteristics of the MLCC family, and the assured availability of a mainstream part number from an established supplier. Engineers may also choose this exact part to maintain consistency across multiple production batches or design revisions, where component switching could introduce unexpected electrical behavior or require extensive re-qualification. This capacitor serves as a critical passive element in countless industrial electronics applications, from control systems and power conditioning circuits to telecommunications infrastructure and instrumentation, where reliability and predictable electrical performance are non-negotiable.
