12105C474KAT4A

The 12105C474KAT4A is a multilayer ceramic capacitor (MLCC) manufactured by AVX, a well-established supplier of passive electronic components. This capacitor belongs to the 1210 package family, which refers to its physical dimensions and fits within the mid-range size category for surface-mount applications. Multilayer ceramic capacitors are fundamental passive components used extensively across industrial, consumer, and commercial electronics for energy storage, filtering, decoupling, and signal conditioning purposes. Multilayer ceramic capacitors function by storing electrical charge across multiple layers of ceramic dielectric material interleaved with metal electrodes. The 1210 package size offers a practical balance between capacitance density and ease of handling during PCB assembly. These components are widely specified in power supplies, audio equipment, telecommunications infrastructure, automotive electronics, industrial control systems, and medical devices where reliable capacitive performance is required. The AVX manufacturing heritage ensures consistent quality and reliability. AVX's MLCC products are designed to meet strict performance standards commonly required in industrial applications where component longevity and stable operation across temperature and voltage ranges are critical. The 1210 package is particularly favored in applications where space constraints are moderate and higher capacitance values are needed compared to smaller packages like 0805 or 0603. An engineer might specify this particular part number for several reasons. The 1210 form factor provides better volumetric efficiency than smaller packages while remaining practical for standard PCB assembly processes. AVX's reputation for consistent dielectric performance and low equivalent series resistance (ESR) makes their capacitors suitable for demanding applications. The specific designation within this part number indicates particular electrical characteristics—likely related to voltage rating, capacitance value, and temperature coefficient—that satisfy precise circuit requirements. This component would typically be selected when designers need reliable energy storage or filtering in applications ranging from industrial control boards to embedded systems. The multilayer ceramic construction provides stable performance across the operating temperature range typical of industrial environments, and the robust manufacturing process minimizes the risk of premature failures. Engineers comparing alternatives would evaluate factors such as capacitance value, voltage rating, temperature stability, and physical footprint compatibility with their PCB layout. The 1210 package offers advantages over both smaller packages (which may have insufficient capacitance) and larger packages (which consume more board space). For applications where AVX's specific performance characteristics align with circuit requirements, this part number represents a proven, manufactured solution with established supply chains.
