12101C103KAT2A

The 12101C103KAT2A is a multilayer ceramic capacitor (MLCC) manufactured by AVX, a leading supplier of passive electronic components. This capacitor belongs to the 1210 package family, which refers to its physical dimensions in metric notation (12.7mm × 10.2mm), making it a moderately sized surface-mount component suitable for a wide range of industrial and commercial applications. MLCCs like this part are fundamental passive components used in virtually every modern electronic circuit. They function primarily to store electrical charge, filter noise from power supplies, couple and decouple signals, and stabilize voltage in analog and digital circuits. The "C103" designation in the part number indicates this is a ceramic capacitor with a specific capacitance value and voltage rating within AVX's naming convention, positioning it as a general-purpose component for mainstream industrial applications. The 1210 package size represents a practical middle ground in surface-mount capacitor selection. It offers better volumetric efficiency than larger packages while providing more robust mechanical and electrical performance than smaller variants like 0805 or 0603 packages. This makes it particularly popular in power distribution circuits, filtering stages, and decoupling applications in industrial control systems, instrumentation, telecommunications equipment, and consumer electronics. AVX capacitors in this package family are typically designed for applications requiring reliable performance across extended temperature ranges and operational lifespans. The MLCC construction provides excellent frequency response characteristics, making these parts suitable for both DC bias and AC signal applications. Engineers often specify 1210 package capacitors when they need a component that balances cost-effectiveness with sufficient electrical performance and physical robustness. An engineer might select the 12101C103KAT2A specifically when design requirements call for the precise capacitance value it represents, combined with AVX's established reliability in industrial environments. AVX's multilayer ceramic capacitors are known for consistent quality and availability, factors that matter significantly in manufacturing environments where supply chain predictability is critical. The 1210 package also provides adequate board real estate and handling characteristics for automated assembly processes while delivering the electrical performance needed in modern power electronics and signal processing circuits. This component would typically be found in power supply filter networks, decoupling circuits near integrated circuits, signal coupling stages, and noise suppression applications throughout industrial equipment, factory automation systems, and networked devices requiring dependable passive component performance.
