0805YD474KAT2A

The AVX 0805YD474KAT2A is a multilayer ceramic capacitor (MLCC) designed for general-purpose energy storage and filtering applications in electronic circuits. This component belongs to the 0805 package family, one of the most widely used surface-mount capacitor formats in modern electronics manufacturing, offering a compact footprint that balances performance with ease of assembly on standard production equipment. Multilayer ceramic capacitors are fundamental building blocks in virtually all electronic applications. They function as charge storage devices, noise filters, and coupling/decoupling elements in power distribution networks. The 0805 package—measuring approximately 2.0mm × 1.25mm—represents an industry-standard size that fits between larger 1206 packages offering greater capacitance and smaller 0603 packages used in space-constrained designs. This middle-ground positioning makes 0805 capacitors the default choice for many general industrial and consumer applications. The "YD" designation in this part number indicates this capacitor uses a Y5V dielectric material. Y5V dielectrics are characterized by broader operating temperature ranges and higher volumetric efficiency compared to other ceramic dielectric classes, making them suitable for applications where temperature stability is secondary to achieving necessary capacitance in limited board space. This material class is commonly found in automotive, industrial control, telecommunications infrastructure, and consumer electronics where cost and compactness are prioritized over tight tolerance specifications. Engineers typically specify this part for applications such as power supply bypassing, noise suppression on signal lines, EMI filtering, and general smoothing functions in DC circuits. The 0805 form factor integrates seamlessly into high-density PCB designs and works reliably with automated pick-and-place assembly processes. The AVX brand brings established manufacturing quality and consistency, making this component a dependable choice for production environments where supply chain reliability matters. When selecting among competing 0805 capacitors, engineers choose the 0805YD474KAT2A based on matching the specific capacitance value and voltage rating required by their circuit design. The widespread availability of 0805 components means designers have flexibility in sourcing, and the standardized package dimensions ensure compatibility across different manufacturers' component libraries and assembly workflows. This capacitor is suitable for use in industrial automation, power electronics, test and measurement equipment, and embedded systems where rugged operation across varying environmental conditions is expected. Its proven reliability in field applications across multiple decades of electronic design makes it a conservative specification choice for engineers prioritizing predictability and long-term availability over exotic performance characteristics.
