2220HA101JAT12

The 2220HA101JAT12 is a multilayer ceramic capacitor (MLCC) manufactured by AVX, one of the leading suppliers of passive electronic components. This part belongs to the 2220 package family, which refers to its physical dimensions in metric notation (approximately 5.6mm x 5.1mm), making it a relatively large surface-mount capacitor suitable for applications requiring moderate to higher capacitance values in compact form factors. Multilayer ceramic capacitors like this unit are fundamental passive components used across virtually all modern electronic equipment. They function to store and release electrical charge, filter noise, decouple power supplies, and stabilize voltage in circuits. The MLCC construction—consisting of multiple layers of ceramic dielectric material interleaved with metal electrodes—allows manufacturers to achieve significant capacitance in a small footprint while maintaining reliable performance across temperature ranges and operating conditions typical in industrial and commercial environments. The 2220 package size positions this capacitor in the mid-range of surface-mount offerings. It provides better volumetric efficiency than smaller packages (0603, 0805, 1206) while remaining easier to handle and reflow than larger alternatives. This makes the 2220 package popular in applications where space is moderately constrained but where designers need adequate capacitance without resorting to bulky through-hole components or multiple smaller units in parallel. AVX's ceramic capacitors are widely specified in industrial electronics, automotive systems, telecommunications equipment, power management circuits, and consumer electronics. The 2220 format is particularly common in power supply filtering, where capacitors must handle moderate to high current ripple and maintain stability across varying load conditions. Engineers often choose this package size when designing boards that require a balance between component density and thermal management, or when working with established design standards that call for 2220-rated capacitors. The specific designation within AVX's product line indicates particular electrical characteristics suited to general-purpose applications. Engineers select the 2220HA101JAT12 when their circuit requirements align with this part's voltage, capacitance, and temperature coefficient specifications. Compared to smaller alternatives, the 2220 package offers lower equivalent series resistance (ESR) and better current handling per unit, which reduces heat generation in demanding applications. Compared to larger packages, it saves board space and weight while still providing practical capacitance levels. This component is suitable for designers prioritizing reliability and performance consistency in industrial and commercial electronics where proven component families from established manufacturers are preferred over cost-minimized alternatives.
