1206CA221KAT1A

The 1206CA221KAT1A is a multilayer ceramic capacitor manufactured by AVX in the widely-used 1206 surface-mount package. This component is part of AVX's established ceramic capacitor product family, designed to serve as a general-purpose energy storage and filtering element in electronic circuits across industrial and commercial applications. Multilayer ceramic capacitors like this unit function as passive components that store and release electrical charge, making them essential for power supply filtering, signal coupling, decoupling, and noise suppression in modern electronics. The 1206 package format—measuring approximately 3.2mm by 1.6mm—represents one of the most common and economical surface-mount sizes in the industry, offering a practical balance between component density and ease of assembly. This capacitor is suitable for inclusion in applications ranging from power management circuits and audio equipment to telecommunications infrastructure, industrial control systems, and consumer electronics. Engineers frequently specify ceramic capacitors in this package type when board space is constrained but component reliability and performance are critical. The 1206 format provides superior mechanical robustness compared to smaller packages, with better resistance to mechanical stress and thermal cycling during manufacturing and field operation. AVX's ceramic capacitor series is known for stable performance across typical industrial operating conditions. Components in this family generally exhibit predictable behavior with temperature and voltage variations, making them suitable for applications where consistent capacitive characteristics are required. The multilayer ceramic construction provides high capacitance density, meaning designers can achieve required capacitance values without excessive board area consumption. Typical selection criteria for specifying a capacitor of this type include the required capacitance value, voltage rating, operating temperature range, and dielectric class. Engineers choose surface-mount ceramic capacitors over alternatives like film or electrolytic capacitors when compact size, high reliability, cost-effectiveness, and compatibility with automated assembly processes are priorities. The 1206 size remains the preferred choice in many industrial applications because it delivers a proven combination of performance, manufacturability, and long-term supply availability. The 1206CA series represents a mature, widely-deployed component technology with extensive manufacturing experience and established supply chains, making it a reliable choice for both new designs and replacement requirements in legacy systems. This familiarity and standardization make the 1206 format a logical specification for engineers designing circuits with stringent reliability requirements.
