1812CA622JAT1A

The 1812CA622JAT1A is a multilayer ceramic capacitor (MLCC) manufactured by AVX, one of the leading suppliers of passive components for industrial and commercial electronics. This component features an 1812 case size, which refers to the imperial dimensions of 0.180 inches by 0.120 inches, making it suitable for compact circuit board layouts while maintaining reasonable capacitance and voltage handling capabilities. Multilayer ceramic capacitors in the 1812 package are widely used across industrial, telecommunications, automotive, and consumer electronics applications where space constraints and cost efficiency are important design considerations. The 1812 form factor represents a popular mid-range size that offers a practical balance between miniaturization and performance, fitting between smaller 0805 and 0603 packages and larger 2220 components. AVX's 1812 series capacitors are commonly specified in power supply circuits, filtering applications, timing circuits, and coupling/decoupling roles throughout industrial control systems, motor drives, LED lighting systems, and embedded computing hardware. The ceramic dielectric material provides stable performance across operational temperature ranges typically encountered in industrial environments, with relatively low equivalent series resistance (ESR) compared to other dielectric types. The CA series designation from AVX indicates this is a standard MLCC line designed for general-purpose industrial applications. These capacitors are known for reliable long-term performance in harsh environments, with construction methods that provide good mechanical robustness and vibration resistance—critical factors in industrial equipment, manufacturing automation, and transportation applications. An engineer might specify the 1812CA622JAT1A over alternatives for several reasons. First, the 1812 package size offers sufficient performance capacity while consuming minimal board space in applications where layout density matters. Second, AVX components generally provide consistent quality and long-term availability, important for production runs and equipment that must remain serviceable over many years. Third, this specific part number indicates a particular capacitance and voltage rating combination optimized for common industrial circuit requirements, reducing the need for design workarounds or compromises in adjacent circuit components. The CA series operates across standard industrial temperature ranges and maintains predictable electrical characteristics within accepted tolerances, making it suitable for equipment designed to function reliably in manufacturing facilities, outdoor installations, and other demanding environments where component stability is essential to overall system performance and longevity.
