0805YC684M4T2A

The 0805YC684M4T2A is a multilayer ceramic capacitor (MLCC) manufactured by AVX, one of the industry's established capacitor producers. This component uses the industry-standard 0805 surface mount package, which measures approximately 2.0mm by 1.25mm, making it suitable for compact circuit board layouts where space constraints are critical. Multilayer ceramic capacitors like this model are fundamental passive components used extensively in electronic circuits for energy storage, filtering, decoupling, and signal coupling applications. The 0805 package size represents a common middle ground in the SMD capacitor spectrum—larger than 0603 packages but smaller than 1206—offering designers flexibility in board density while maintaining reasonable manufacturing accessibility and hand-solderability margins. This particular AVX part belongs to the general class of general-purpose ceramic capacitors, which are widely used across consumer electronics, industrial control systems, telecommunications equipment, and automotive applications. These capacitors excel in high-frequency filtering, power supply decoupling near integrated circuits, and bypass applications where cost-effectiveness and reliability are balanced requirements. The ceramic dielectric material provides stable performance across a wide temperature range, making these components suitable for applications from consumer to industrial environmental conditions. Engineers typically specify this exact part number when they need a compact, cost-effective capacitor solution that meets specific voltage and capacitance requirements within the 0805 footprint. AVX's reputation for manufacturing consistency and reliability makes their capacitors preferred choices in applications where component failure rates must be minimized. The standardized 0805 package also ensures broad compatibility with automated assembly processes and design tool libraries, reducing engineering and manufacturing complexity. The ceramic construction of multilayer capacitors like this one offers excellent frequency response characteristics, making them particularly valuable in RF and high-speed digital circuits where capacitive reactance across frequency bands must be carefully controlled. Unlike some alternative technologies, ceramic capacitors provide dependable performance without requiring the volumetric footprint of electrolytic alternatives, though engineers must consider the dielectric absorption characteristics typical of ceramic formulations when precision analog applications demand it. For replacement or new design applications, this part number offers a proven, readily-sourced solution that integrates easily into established manufacturing processes. The 0805 footprint has remained standardized across decades of electronics manufacturing, ensuring long-term component availability and manufacturing continuity—an important consideration for industrial equipment with extended service life requirements.
