12063A103KAT2A

The 12063A103KAT2A is a multilayer ceramic capacitor (MLCC) manufactured by AVX, one of the leading producers of passive electronic components. This part represents a standard, general-purpose capacitor designed for use in a wide range of electronic circuits and applications where reliable energy storage and filtering are required. Multilayer ceramic capacitors like this model are among the most widely used passive components in modern electronics. They function by storing electrical charge between ceramic layers and metal electrodes, making them essential for applications including power supply filtering, signal coupling and decoupling, noise suppression, and timing circuits. The compact size and relatively low cost of ceramic capacitors have made them the default choice across consumer electronics, industrial control systems, telecommunications equipment, and automotive applications. The part designation 12063A103KAT2A indicates this capacitor uses a 1206 package format, which refers to surface-mount dimensions of approximately 3.2mm by 1.6mm. This size strikes a practical balance—small enough for modern high-density PCB designs, yet large enough to handle reasonable power levels and provide adequate physical durability during manufacturing and field use. The 1206 package remains one of the most common footprints in industrial and consumer electronics because it offers good manufacturability with standard pick-and-place equipment while maintaining reasonable performance characteristics. AVX's capacitors in this family are generally specified for general industrial and commercial applications. Engineers typically select MLCCs like this model when cost-effectiveness, reliability, and space constraints are balanced priorities. These capacitors work well in non-critical filtering roles, decoupling applications, and circuits where the operating environment is relatively stable. Engineers might specify this exact part when they need a proven, readily available capacitor from a recognized manufacturer with established supply chain reliability. AVX components are known for consistent quality and broad distribution through electronics suppliers, which can be important for production continuity. The 1206 package size also provides compatibility with standard PCB assembly processes and rework procedures, reducing manufacturing complexity. This capacitor would typically be used alongside other passive and active components in applications ranging from industrial automation and power management circuits to consumer electronics and embedded systems. When specifying ceramic capacitors for any application, engineers consider factors including the required capacitance value, voltage rating, operating temperature range, and the specific role the capacitor plays in the circuit—whether for high-frequency filtering, DC blocking, or energy storage.
