0805YD684MAT2A

The 0805YD684MAT2A is a multilayer ceramic capacitor (MLCC) manufactured by AVX, designed for use in a wide range of electronic applications requiring reliable energy storage and filtering. This component belongs to the general-purpose film and ceramic capacitor family, making it suitable for both consumer and industrial electronics where cost-effectiveness and compact form factors are priorities. The part uses a 0805 surface-mount package, which is one of the most common standardized sizes in modern electronics manufacturing. This package type measures 0.08 by 0.05 inches (approximately 2.0 by 1.25 millimeters), making it small enough for high-density PCB layouts while remaining straightforward to handle and solder with standard automated assembly equipment. The 0805 form factor strikes a practical balance between miniaturization and ease of production, which explains its widespread adoption across automotive, telecommunications, consumer, and industrial control sectors. MLCCs like this part are fundamental building blocks in power supply circuits, decoupling networks, signal filtering, and timing applications. Engineers commonly specify ceramic capacitors in bypass configurations to suppress high-frequency noise near integrated circuit power pins, in input and output filters for switched-mode power supplies, and in RF and analog signal paths where stable capacitance is required across operating temperature ranges. AVX's ceramic capacitor lines are recognized in the industry for consistent quality and reliable performance in mainstream applications. The "YD" designation in the part number indicates this is a general-purpose ceramic capacitor rather than a specialized high-reliability, high-temperature, or high-voltage variant. This positioning makes it appropriate for cost-sensitive designs where standard commercial-grade performance meets application requirements. An engineer might select this exact part when the application calls for a standard ceramic capacitor in a compact surface-mount package, when design boards are already committed to 0805 footprints, or when supply chain standardization on AVX components is a manufacturing priority. The 0805 size also allows for straightforward substitution with other vendors' parts in the same package should supply considerations arise, though component-level electrical matching remains important in sensitive circuits. This capacitor is commonly found in consumer electronics, industrial control systems, LED drivers, audio amplifiers, DC-DC converters, and general-purpose filtering applications where reliability and cost are both important considerations.
