08055C221KAT2A

The AVX 08055C221KAT2A is a multilayer ceramic capacitor (MLCC) in the 0805 surface-mount package, a standard form factor widely used in modern electronics manufacturing. This component belongs to AVX's established portfolio of general-purpose ceramic capacitors designed for applications requiring compact, reliable energy storage and signal conditioning. Multilayer ceramic capacitors like this model function as passive components that store and release electrical energy, filter noise from power supply lines, and couple or decouple signals in circuits. The 0805 package designation indicates physical dimensions of approximately 2.0mm by 1.25mm, making it suitable for high-density circuit board layouts where space is at a premium. This compact footprint has become standard in consumer electronics, industrial control systems, telecommunications equipment, and automotive electronics. The "221" designation in the part number typically indicates the capacitance value within AVX's naming convention. MLCCs in this general range are employed in numerous roles: smoothing ripple on DC power rails, bypassing high-frequency noise near integrated circuit power pins, timing circuit applications, and AC coupling between amplifier stages. Engineers frequently specify capacitors of this type in power management circuits, audio signal paths, RF circuitry, and digital logic subsystems. AVX ceramic capacitors are known for consistent dielectric performance across temperature ranges typical of industrial and commercial environments. The 0805 package offers advantages including ease of automated placement during assembly, reliable soldering characteristics with lead-free processes, and proven field reliability across decades of production. These capacitors can be sourced with various dielectric materials and voltage ratings to match specific circuit requirements, from low-voltage consumer applications to higher-voltage industrial control scenarios. Engineers might select this particular AVX part when designing circuits that require a proven, readily-available capacitor in a standard package. The combination of established manufacturer reputation, widespread circuit board design compatibility, and availability through multiple distribution channels makes it a practical choice for production applications where supply chain consistency matters. The 0805 form factor also simplifies design flexibility—many reference designs and application notes reference components in this package, reducing engineering validation time. For applications demanding specific electrical performance characteristics such as particular voltage ratings, temperature coefficients, or ESR specifications, engineers would confirm the exact variant's suitability through published technical documentation. The modular nature of AVX's ceramic capacitor offerings means multiple versions of the 08055C221KAT2A designation exist, each optimized for different performance requirements and operating conditions.
