0805YC823KAT4A

The 0805YC823KAT4A is a multilayer ceramic capacitor (MLCC) manufactured by AVX in the widely-used 0805 surface-mount package. This component belongs to the Y5V dielectric class, which is characterized by capacitors designed for general-purpose applications where moderate capacitance stability across temperature and voltage ranges is acceptable. The part designation indicates a nominal capacitance value in the low microfarad range, making it suitable for coupling, decoupling, and filtering applications throughout industrial and consumer electronics. The 0805 package size represents one of the most standardized surface-mount formats in modern PCB design. At approximately 2.0mm × 1.25mm, this compact footprint allows for high-density board layouts while remaining large enough for reliable hand-soldering and automated assembly processes. The 0805 form factor has become the practical sweet spot for engineers balancing space constraints with ease of manufacture and repairability. Y5V capacitors like this part are typically specified in applications where cost-effectiveness and board space are priorities, and where strict capacitance stability is not critical. Common use cases include power supply filtering on secondary rails, EMI suppression, signal coupling between stages, and general-purpose energy storage in industrial control circuits, telecommunications equipment, and consumer electronics. These capacitors excel in applications operating at moderate to elevated temperatures where their relaxation characteristics remain acceptable for the intended function. AVX's 0805YC series represents a mainstream offering in the capacitor market, backed by established manufacturing processes and widespread availability through distribution channels. Engineers often specify this series when designing cost-sensitive applications that require reliable, proven components with well-documented assembly characteristics. The 0805 package's dominance in the industry means that design tools, assembly equipment, and replacement stock are readily available, reducing supply chain risk. Key reasons an engineer might select this exact part include the combination of package standardization, manufacturer reputation for quality, and the proven track record of the Y5V dielectric class in consumer and industrial applications. While Y5V capacitors exhibit greater capacitance drift with temperature and applied voltage compared to more stable C0G or X7R alternatives, their lower cost and smaller physical size make them the appropriate choice when application requirements permit. For engineers designing new products or upgrading existing designs, the 0805YC823KAT4A offers a proven, economical solution within a trusted component family. Verification of electrical requirements against your specific application parameters is recommended before final design approval.
