0805YC563KAT4A

The 0805YC563KAT4A is a multilayer ceramic capacitor (MLCC) manufactured by AVX in the widely-used 0805 surface mount package. This component belongs to the general-purpose ceramic capacitor family, designed for applications requiring reliable energy storage, filtering, and signal coupling in electronic circuits. The 0805 package size represents a standard footprint measuring approximately 2.0 mm by 1.25 mm, making it suitable for modern compact circuit board designs. This package format has become the industry workhorse for mid-range capacitance values in consumer, industrial, and automotive electronics due to its excellent balance between physical size, electrical performance, and cost-effectiveness. The component is intended for surface mount assembly, enabling high-speed automated production processes. AVX's ceramic capacitor portfolio, which includes this part, is recognized for consistent manufacturing quality and reliable performance across commercial and industrial temperature ranges. Multilayer ceramic capacitors in this class are commonly specified in applications including power supply filtering, decoupling near integrated circuits, timing circuit stabilization, and AC signal coupling. They are particularly valuable in digital logic circuits where quick transient response and compact form factor are important design considerations. Engineers typically select the 0805YC563KAT4A based on several factors specific to their circuit requirements. The exact capacitance value encoded in the part number makes this component suitable for particular resonant frequencies, filter cutoff points, or charge storage needs within a defined circuit topology. When compared to alternative package sizes or dielectric materials, the 0805 format offers practical advantages: it is large enough to achieve useful capacitance values without excessive cost, yet small enough to support high-density PCB layouts. The ceramic dielectric provides stable performance across moderate temperature variations, acceptable for most industrial and consumer applications. The "YC" designation within AVX's naming convention typically indicates this capacitor falls within their standard commercial-grade ceramic capacitor line, which has established reliability data from widespread deployment in field applications. This makes it a lower-risk specification choice for design engineers who can reference proven performance history. For applications requiring extreme reliability, specialized temperature coefficients, or unusual electrical characteristics, alternative capacitor families or manufacturers might be more appropriate. However, for general-purpose filtering, coupling, and decoupling applications in standard industrial and commercial electronics, the 0805 multilayer ceramic capacitor remains the default choice due to its proven performance, cost efficiency, and broad availability across the electronics supply chain.
