1812CA390JAT1A

The 1812CA390JAT1A is a multilayer ceramic capacitor (MLCC) manufactured by AVX, a leading supplier of passive electronic components. This capacitor features a 1812 package size, which refers to its physical dimensions in the metric system (approximately 4.5mm × 3.2mm), making it suitable for applications requiring moderate capacitance in a compact form factor. The component is designed for use in standard industrial and commercial electronic assemblies where space efficiency and reliability are important considerations. Multilayer ceramic capacitors like this model are fundamental building blocks in modern electronics, serving critical functions in filtering, coupling, decoupling, and energy storage applications. They are widely used in power supply circuits, audio equipment, telecommunications infrastructure, industrial control systems, and consumer electronics. The 1812 package size represents a middle ground in the MLCC spectrum, offering more capacitance than smaller packages while remaining relatively compact for PCB integration. AVX's ceramic capacitor products are engineered to meet strict industrial standards and are commonly specified in applications demanding consistent performance across temperature and voltage ranges. MLCCs in this size category typically offer good volumetric efficiency, meaning they can store substantial charge relative to their physical footprint. This makes them particularly valuable in designs where board space is constrained or where multiple capacitors must work together in filtering networks. Engineers select this specific part number when they need a reliable, proven ceramic capacitor solution that fits established design requirements and manufacturing processes. The 1812 form factor has decades of industry adoption, meaning compatibility with standard PCB assembly equipment, well-documented thermal characteristics, and widespread familiarity among design teams. Choosing an established manufacturer like AVX provides engineers with confidence in component longevity, consistent electrical performance, and availability across multiple production runs. The multilayer ceramic construction provides stable performance and excellent high-frequency characteristics compared to some alternative capacitor technologies. This makes the 1812CA390JAT1A and similar components suitable for signal conditioning, noise suppression, and bypass applications in both analog and digital circuits. Industrial and engineering buyers typically specify MLCCs from established manufacturers when designing equipment requiring high reliability, predictable performance over time, and minimal field failures. For specific electrical characteristics, operating conditions, and application guidance, technical documentation from the manufacturer should be consulted during the design phase to ensure proper component selection for your particular application requirements.
