1812CA470JAT1A

The 1812CA470JAT1A is a multilayer ceramic capacitor (MLCC) manufactured by AVX, belonging to the widely-used 1812 package family. This component is designed for general-purpose energy storage, filtering, and signal coupling applications across industrial and commercial electronics. Multilayer ceramic capacitors in the 1812 form factor are among the most common passive components found in modern electronics. The "1812" designation refers to the physical dimensions of the component (approximately 4.5mm × 3.2mm × 1.6mm), making it suitable for compact circuit board layouts while offering reasonable capacitance values and voltage ratings. AVX's 1812 series components are engineered for reliability in demanding environments, from consumer devices to industrial control systems and power supplies. This particular part carries the "CA" dielectric designation, which typically indicates a standard ceramic dielectric suited for applications where moderate capacitance stability and good high-frequency performance are required. The "470J" marking indicates the nominal capacitance value and tolerance class. Capacitors in this range are frequently selected for decoupling, bypass filtering, and EMI suppression in digital circuits, power distribution networks, and analog signal conditioning stages. Engineers commonly specify AVX 1812 ceramic capacitors when they need a balance between cost-effectiveness, reliability, and performance. The compact 1812 package allows designers to achieve effective filtering and energy storage without consuming excessive board space—a critical consideration in dense PCB layouts. These capacitors exhibit stable performance across typical industrial temperature ranges and are resistant to mechanical stress from thermal cycling, making them suitable for both consumer and harsh industrial environments. Typical applications include power supply filtering in microprocessor circuits, decoupling in mixed-signal designs, timing circuits, and noise suppression near high-speed digital logic. The multilayer construction provides low equivalent series resistance (ESR) and inductance (ESL), which is important for high-frequency filtering and signal integrity in modern electronics. When selecting this specific part, engineers appreciate AVX's manufacturing consistency, the proven reliability of the 1812 package in high-volume production, and the availability of detailed performance data from the manufacturer. The ceramic dielectric formulation offers good temperature stability while maintaining cost competitiveness compared to alternative dielectric materials. This part is particularly favored in applications requiring standard, off-the-shelf components with established supply chain presence and no exotic material requirements.
