1808HA220KAT1A

The AVX 1808HA220KAT1A is a multilayer ceramic capacitor (MLCC) designed for general-purpose applications in industrial and commercial electronics. This component belongs to the 1808 package family, which represents a surface-mount chip capacitor with compact dimensions suitable for high-density circuit board layouts. The part is manufactured by AVX, a recognized producer of passive components widely used in demanding applications. Multilayer ceramic capacitors like this unit are fundamental building blocks in modern electronic equipment. They are used for decoupling, filtering, energy storage, and signal coupling across a broad range of circuits. The 1808 package size offers a practical balance between capacitance density and ease of handling during manufacturing, making it popular in both consumer and industrial product design. This specific part number indicates a capacitor with a capacitance value in the 22 microfarad range, though the precise tolerance and temperature coefficient are encoded in the complete designation. The HA designation in AVX's naming convention typically points to a component optimized for temperature stability and reliability across extended operating ranges, characteristics that matter significantly in industrial control systems, power supplies, audio equipment, and telecommunications infrastructure. Engineers typically select parts from this family when they need reliable capacitive filtering in power delivery networks, or when space constraints demand efficient use of board real estate. The 1808 footprint is small enough to fit densely packed circuit boards while remaining large enough to achieve substantial capacitance values without excessive cost. The AVX family of MLCCs is known for consistent quality and availability, which reduces design risk for manufacturers planning long production runs. Applications commonly encountered with this component include power management modules, LED driver circuits, automotive electronics, industrial frequency drives, and embedded control systems. The multilayer construction provides self-healing characteristics, enhancing reliability in field environments where voltage transients or thermal cycling might occur. When selecting between competing alternatives, engineers consider several factors specific to their design: the exact capacitance and voltage rating required, the temperature operating range needed, the physical space available on the board, and the cost implications of the chosen solution. The 1808 package sits at an accessible price point while delivering performance suitable for non-critical filtering and decoupling duties, making it a pragmatic choice for cost-conscious designs that still demand dependable component behavior. This capacitor is suitable for engineers designing systems requiring proven, readily-available passive components that prioritize reliability and thermal stability in industrial environments.
