12061A271KAT2A

The AVX 12061A271KAT2A is a multilayer ceramic capacitor (MLCC) designed for general-purpose energy storage and filtering applications in electronic circuits. This component belongs to the 1206 package family, one of the most widely used surface-mount capacitor formats in modern electronics manufacturing. Multilayer ceramic capacitors like this part are fundamental building blocks in contemporary circuit design. They function by storing electrical energy in an electric field between multiple ceramic layers, with metallic electrodes deposited between them. Engineers rely on these capacitors for essential functions including power supply filtering, signal coupling, decoupling, and bypassing applications across countless industries. The 1206 package designation refers to the component's physical dimensions in imperial notation (0.126 inches by 0.063 inches), making it a mid-sized surface-mount device. This package size offers a practical balance between capacitance density and ease of assembly with standard pick-and-place equipment. It's large enough to accommodate reasonable capacitance values while remaining compact enough for space-constrained designs. AVX Corporation, a leading manufacturer of passive electronic components, produces capacitors known for reliability and consistent performance across temperature and frequency ranges. The "A" designation in the part number typically indicates the component's temperature coefficient class, affecting how capacitance varies with temperature changes—an important consideration in applications subject to thermal cycling or extreme environmental conditions. Engineers specify this exact part number when their circuit design calls for a specific capacitance value combined with the dimensional and electrical characteristics of the 1206 package. Common scenarios include filtering and stabilizing power delivery in consumer electronics, industrial control systems, telecommunications equipment, automotive electronics, medical devices, and computing hardware. The ceramic composition provides excellent frequency response, making these capacitors suitable for both DC filtering and AC coupling applications. The MLCC format offers advantages over alternative capacitor technologies in many applications, including compact size, low equivalent series resistance, high volumetric efficiency, and cost-effectiveness at volume. Engineers often select MLCCs when weight and board space are constrained, when rapid charge-discharge cycles are required, or when the application demands reliable performance over extended product lifecycles. Proper selection of MLCC part numbers requires careful consideration of working voltage, capacitance value, and application environment. The 1206 package remains a versatile choice across industrial and commercial electronics design, from prototype development through high-volume manufacturing. This particular AVX offering represents a proven solution for designers seeking standardized, dependable passive component performance.
