0805YC103KAT2A

The 0805YC103KAT2A is a multilayer ceramic capacitor (MLCC) manufactured by AVX in the compact 0805 surface-mount package size. This component belongs to the broad family of film and ceramic capacitors used across countless electronics applications, from consumer devices to industrial control systems. Multilayer ceramic capacitors in the 0805 package are among the most widely used passive components in modern electronics. They serve as energy storage, filtering, decoupling, and noise suppression elements in power supplies, signal conditioning circuits, and digital logic boards. The 0805 form factor—measuring 2.0mm by 1.25mm—offers a practical balance between compact footprint and ease of hand assembly or automated pick-and-place manufacturing, making it the default choice for most mainstream applications where space is moderately constrained but not critically limited. AVX's ceramic capacitor series emphasizes reliability and cost-effectiveness for high-volume production environments. These capacitors are constructed from multiple layers of ceramic dielectric material with alternating metal electrodes, then terminated with solderable end caps. This construction allows the manufacturer to achieve useful capacitance values in very small volumes while maintaining reasonable voltage ratings for most general-purpose circuits. The "Y" in the part designation typically indicates this capacitor is formulated for general-purpose, mid-range performance rather than specialized military or high-reliability specifications. This positioning makes it suitable for standard industrial, automotive, telecommunications, and consumer applications where performance requirements are well-defined but not extreme. Engineers specify AVX ceramic capacitors for several practical reasons: consistent lead times and broad availability through distribution channels, proven field reliability across millions of deployed units, straightforward electrical characteristics that simplify circuit design, and cost efficiency when purchasing in volume. The 0805 package remains the industry standard reference point for passive component miniaturization, ensuring compatibility with established manufacturing processes and design tools. Common use cases include DC power supply filtering, AC coupling in amplifier stages, EMI/RFI suppression near high-speed digital logic, and stabilization of voltage regulator circuits. The MLCC family's temperature stability characteristics and frequency response make them particularly valuable for applications experiencing thermal cycling or wide operating temperature ranges. For engineers evaluating this part, consideration should be given to the specific voltage rating, capacitance value, and temperature coefficient required by the application. AVX produces variants of this package and designator family across a range of electrical specifications to support different circuit requirements, so confirming the exact electrical properties matches your design needs is essential before procurement.
