08055C104KA12A

The AVX 08055C104KA12A is a multilayer ceramic capacitor (MLCC) designed for general-purpose and industrial electronic applications. This component belongs to the 0805 package family, one of the most widely used surface-mount capacitor formats in modern electronics manufacturing. The 0805 designation refers to the physical dimensions of the component (approximately 2.0mm × 1.25mm), making it compact enough for high-density circuit board layouts while remaining accessible for standard assembly equipment and rework procedures. MLLCs like this part are fundamental passive components used to filter noise, stabilize power supplies, couple and decouple AC signals, and support timing circuits across countless applications. The "C" in the part number typically indicates a ceramic dielectric material, which provides excellent frequency response characteristics and stability across industrial temperature ranges. This makes the component suitable for both consumer-grade and demanding industrial environments. The 08055C104KA12A is commonly specified in power management circuits, audio equipment, telecommunications infrastructure, automotive electronics, industrial control systems, and various consumer appliances. Engineers select MLLCs for applications requiring high reliability, compact footprints, and cost-effectiveness at volume. The ceramic dielectric technology offers superior performance in high-frequency applications compared to some alternative capacitor technologies, with minimal parasitic effects. This part number's inclusion of "KA" in its designation suggests specific performance parameters within AVX's product range, likely indicating particular tolerances or performance grades that differentiate it from similar devices in the 0805 family. Engineers typically choose this exact part when their circuit design requires the specific electrical characteristics and reliability ratings that this particular variant provides, rather than opting for generic alternatives with less defined performance envelopes. The 0805 form factor has become an industry standard, ensuring that design teams can source compatible components from multiple suppliers if needed, though many engineers prefer to maintain consistent vendor specifications for critical applications. The multilayer construction of ceramic capacitors in this package provides stable capacitance across temperature ranges and voltage conditions, making them reliable for long-term deployment in harsh industrial environments. Typical applications include decoupling capacitors on power supply rails, AC coupling in signal paths, EMI filtering in power distribution networks, and energy storage in timing circuits. The compact surface-mount design reduces assembly costs and board real estate requirements compared to through-hole alternatives, which is a primary reason these components remain ubiquitous in modern electronics design despite advances in alternative technologies.
