12103C105JAT2A

The 12103C105JAT2A is a multilayer ceramic capacitor manufactured by AVX, one of the industry's established suppliers of passive electronic components. This part represents the type of general-purpose capacitor commonly specified in industrial electronics, consumer devices, and telecommunications equipment where reliable energy storage and filtering are required. Multilayer ceramic capacitors (MLCCs) like this unit function as charge storage devices in electrical circuits. They are essential for power supply filtering, signal coupling and decoupling, noise suppression, and timing applications. The ceramic dielectric material allows these capacitors to deliver stable performance across a wide range of operating conditions, making them suitable for both analog and digital circuit designs. The part number structure indicates this is from AVX's established ceramic capacitor family. The "C" designation in the part number identifies it as a capacitor, while the remaining alphanumeric sequence specifies the particular capacitance value, voltage rating, tolerance, temperature coefficient, and package style. The "2A" suffix typically indicates the component's physical size and lead configuration, suggesting a standard surface-mount or conventional package format familiar to design engineers working with industrial-grade components. AVX MLCCs in this series are known for consistent performance in demanding environments. These capacitors are valued for their stability across temperature ranges, low equivalent series resistance (ESR), and reliability in high-cycle applications. Engineers often specify ceramic capacitors from established manufacturers like AVX when circuit designs require components with predictable behavior and proven field performance histories. This particular part would be selected by engineers for applications requiring a specific capacitance value combined with particular voltage handling and temperature characteristics. The specific package style influences its suitability for board layout and thermal management considerations in compact designs. In industrial applications ranging from power conversion equipment to control systems and instrumentation, having the exact part number ensures compatibility with existing designs and maintains procurement consistency. Designers choosing this component over alternatives typically prioritize AVX's manufacturing consistency, the proven reliability of multilayer ceramic technology, and the certainty that this exact part number will meet established circuit requirements. In production environments where component qualification and traceability are important—common in aerospace, medical, and industrial sectors—specifying a known manufacturer's established part number reduces technical risk. For engineers integrating this capacitor into new designs or replacements for existing systems, understanding the component's role in filtering, coupling, or energy storage applications will ensure proper circuit design and optimal system performance.
