12061C821KAT2A

The AVX 12061C821KAT2A is a multilayer ceramic capacitor (MLCC) from AVX's established capacitor product line. This component is designed for general-purpose energy storage and signal coupling applications across industrial, commercial, and consumer electronics equipment. Multilayer ceramic capacitors are fundamental passive components used in virtually every electronic circuit. They provide capacitance for filtering, decoupling, blocking, and bypassing functions. The 12061C821KAT2A is part of AVX's 1206 case size family, which denotes a surface-mount package measuring approximately 3.2mm by 1.6mm. This standard metric package size is widely used in modern PCB designs due to its compact footprint and ease of automated assembly. The part number designation "821K" indicates a capacitance value in the mid-range for general industrial applications. The "AT2A" suffix references AVX's specific dielectric formulation and performance characteristics within their product catalog. This particular variant is typically selected for applications requiring stable performance across standard operating temperature ranges found in industrial environments. Engineers commonly specify MLCCs like this model for power supply decoupling near digital logic ICs, filtering in analog signal chains, and energy storage in timing circuits. The ceramic dielectric provides good frequency response characteristics, making these capacitors suitable for both DC blocking and AC coupling tasks. The surface-mount configuration enables high-density PCB layouts while maintaining reliable solder joint integrity through thermal cycling. AVX MLCCs in the 1206 package are manufactured to IPC and industry standards, ensuring consistent electrical performance and mechanical reliability. The compact size does not compromise robustness—these components are widely used in mission-critical industrial control systems, power electronics, and telecommunications equipment where long service life is essential. When selecting between capacitor alternatives, engineers choose this specific part for several reasons: the proven reliability of AVX's manufacturing processes, compatibility with standard pick-and-place equipment, availability in bulk quantities for volume production, and consistent performance across large manufacturing batches. The 1206 package also represents an optimal balance between size reduction and practical handling during assembly, avoiding the difficulty of smaller packages while providing adequate real estate for the required capacitance value. This capacitor is suitable for applications with moderate voltage and current demands in controlled environments. Its stable ceramic dielectric makes it a dependable choice for industrial equipment requiring consistent performance without specialized environmental conditioning.
