1812CA200KAT1A

The 1812CA200KAT1A is a multilayer ceramic capacitor (MLCC) manufactured by AVX in the 1812 surface-mount package format. This component belongs to the general family of ceramic capacitors designed for broad industrial and commercial electronics applications where compact size, reliability, and cost-effectiveness are important considerations. Multilayer ceramic capacitors like this unit are fundamental building blocks in modern electronics, used primarily for filtering, decoupling, and energy storage functions in power supply circuits, signal processing stages, and high-frequency applications. The 1812 package designation refers to the physical dimensions (approximately 4.5mm × 3.2mm × 1.6mm), making it a medium-sized surface-mount component that balances real estate efficiency with handling ease in automated assembly processes. The "CA" designation in AVX's naming convention typically indicates this capacitor is designed for general-purpose applications with standard performance characteristics. The "200K" element of the part number relates to the capacitance value, suggesting this unit falls within a mid-range capacitance class suitable for typical filtering and coupling applications in consumer and industrial electronics. Engineers often specify AVX multilayer ceramic capacitors for their consistent quality, proven field reliability, and availability across global supply chains. The 1812 case size represents a practical middle ground—larger than smaller 0603 or 0805 packages, which allows for higher capacitance values or better voltage ratings, while remaining significantly more compact than larger through-hole or 1825-sized alternatives. This makes the 1812 package particularly popular in space-constrained designs where component density matters. The ceramic dielectric technology used in these capacitors provides good stability across temperature ranges typical for industrial environments. Designers also appreciate the inherent low equivalent series resistance (ESR) and inductance (ESL) characteristics of multilayer ceramic construction, which make these components effective for high-frequency decoupling and noise suppression tasks alongside traditional bulk filtering functions. Common application areas include motherboards, industrial control systems, telecommunications equipment, automotive electronics, and various power conversion circuits. The combination of AVX's manufacturing reputation, the proven 1812 package form factor, and the general-purpose design of this series makes it a reliable specification choice when engineers need a dependable mid-range ceramic capacitor that integrates easily into standard surface-mount assembly workflows. For specific electrical performance details, rated voltage, temperature coefficients, and tolerance specifications, consulting the manufacturer's datasheet is recommended to ensure this component meets your particular design requirements.
