0805YC102KA12A

The AVX 0805YC102KA12A is a multilayer ceramic capacitor (MLCC) in the 0805 surface-mount package size. This component belongs to AVX's Y5V dielectric family, which represents a general-purpose ceramic capacitor series designed for cost-effective applications where moderate capacitance stability across temperature ranges is acceptable. Multilayer ceramic capacitors are among the most widely used passive components in modern electronics. They function as energy storage and filtering elements in circuits, helping to smooth power supply voltages, couple AC signals, and bypass high-frequency noise to ground. The 0805 package format—measuring approximately 2.0mm × 1.25mm—offers a practical balance between compact size and ease of hand-soldering or automated assembly, making it ideal for both prototyping and high-volume production environments. The Y5V designation indicates this capacitor has a broad but temperature-dependent capacitance characteristic. Y5V-rated ceramics typically experience more significant capacitance variation across temperature extremes compared to premium dielectric classes like X7R or C0G, but this trade-off enables higher volumetric efficiency and lower cost. This makes Y5V capacitors particularly suitable for non-critical filtering, decoupling, and general energy storage roles where precise capacitance stability is less important than density and affordability. Typical applications for 0805 MLCCs include decoupling power supply rails in digital circuits, filtering in audio and analog signal chains, energy storage in switching power supplies, and general-purpose bypass functions across consumer electronics, industrial control boards, and telecommunications equipment. The 0805 format is also common in automotive electronics and IoT devices where space constraints favor smaller components. Engineers might specify the AVX 0805YC102KA12A over alternatives for several reasons. AVX is a well-established manufacturer with consistent quality and wide distribution, ensuring long-term availability for production runs and field repairs. The Y5V family offers predictable performance in non-demanding applications, reducing design complexity. When integrated into larger assemblies requiring hundreds or thousands of capacitors, the standardized 0805 package and Y5V characteristics simplify inventory management and procurement. This part is compatible with standard surface-mount reflow soldering processes and RoHS-compliant manufacturing workflows, meeting regulatory requirements for many markets. Its relatively forgiving electrical performance characteristics make it a reliable workhorse component in applications where cost efficiency and density matter more than exceptional precision or stability.
