0805YC104J4T2A

The 0805YC104J4T2A is a multilayer ceramic capacitor (MLCC) manufactured by AVX, designed for general-purpose applications in electronic circuits. This component belongs to the 0805 package family, one of the most widely used surface-mount capacitor sizes in modern electronics manufacturing. The 0805 package measures 0.080 by 0.050 inches, making it suitable for compact PCB layouts while remaining easy to handle and inspect during assembly. Multilayer ceramic capacitors like this model are fundamental building blocks in circuit design, providing energy storage, signal filtering, noise suppression, and voltage stabilization functions. They are found in virtually every category of electronic equipment, from consumer devices to industrial control systems, telecommunications infrastructure, automotive electronics, and medical instrumentation. The widespread adoption of this component type reflects its excellent balance of cost, reliability, performance, and size efficiency. The specific designation in this part number indicates this capacitor operates in the Y5V or similar dielectric class, which is commonly used for bypass and decoupling applications where tight tolerance and stable capacitance across temperature variations are less critical than in precision analog circuits. Y5V capacitors deliver good capacitance density and are particularly economical, making them ideal for power supply filtering, high-frequency bypassing, and general-purpose smoothing tasks. This makes the 0805YC104J4T2A a practical choice for cost-sensitive production environments where standard performance is acceptable. Engineers typically specify AVX MLCCs when they require established reliability, consistent quality, and broad availability across their supply chain. AVX's manufacturing processes are recognized for producing capacitors suitable for harsh environments and demanding reliability requirements. The 0805 package itself has become an industry standard, ensuring that design decisions remain compatible with common assembly equipment and supplier ecosystems. When selecting between competing capacitors in this category, designers consider several factors beyond capacitance value: the dielectric class and its temperature stability, equivalent series resistance (ESR), frequency response characteristics, voltage rating, and environmental robustness. The 0805 package size offers a practical middle ground between smaller 0603 packages and larger 1206 packages, making it particularly popular in moderate-density designs where component footprint matters but not to the extreme degree required by ultra-compact applications. This component is ideal for engineers working on refresh designs, cost-optimized products, or applications requiring proven, high-volume standard parts with established supply chains and manufacturing processes.
