0805YC684K4T2A

The 0805YC684K4T2A is a multilayer ceramic capacitor (MLCC) manufactured by AVX, designed for general-purpose filtering, decoupling, and signal coupling applications across a wide range of electronic equipment. This component belongs to the 0805 package family, one of the most widely used surface-mount capacitor sizes in modern electronics due to its balance between compact footprint and ease of assembly. The "0805" designation refers to the component's physical dimensions in hundredths of an inch (0.080" × 0.050"), making it suitable for high-density circuit boards where space optimization is critical. This size is particularly popular in consumer electronics, industrial control systems, telecommunications equipment, and automotive applications where designers need reliable capacitance in a small form factor. The part number's construction indicates this is a ceramic capacitor with specific material composition and performance characteristics optimized for standard industrial operating conditions. MLLCs like this part are essential building blocks in modern electronics. They serve multiple functions including power supply decoupling near integrated circuits, high-frequency filtering in signal paths, AC coupling between amplifier stages, and noise suppression in analog and digital circuits. Engineers often specify ceramic capacitors for their excellent frequency response, compact size, and cost-effectiveness compared to alternative technologies like film or electrolytic capacitors. The 0805 package offers several practical advantages for manufacturing and maintenance. The standardized size ensures compatibility with automated assembly equipment found in virtually all PCB manufacturing facilities, reducing production costs and lead times. The component's small footprint allows designers to fit more capacitance into confined spaces, which is particularly valuable in portable devices and space-constrained industrial modules. Additionally, the robustness of modern ceramic technology means these capacitors exhibit good reliability across temperature cycling and vibration, making them suitable for harsh industrial environments. Engineers typically choose AVX multilayer ceramic capacitors when they require a balance of performance, reliability, and availability. AVX is a well-established manufacturer with consistent quality standards and worldwide distribution, making replacement and future sourcing straightforward. The 0805 package represents a mature, proven technology with extensive design reference materials available from the manufacturer and the broader electronics community. This component would be selected by design engineers working on applications ranging from power management circuits to sensor interfaces, where a general-purpose, surface-mount ceramic capacitor meeting standard industrial specifications is appropriate. The combination of proven technology, compact form factor, and manufacturer reputation makes this part a reliable choice for production equipment requiring standard ceramic capacitance.
