12105C184KAT4A

The 12105C184KAT4A is a multilayer ceramic capacitor manufactured by AVX, one of the industry's established producers of passive electronic components. This part belongs to AVX's capacitor portfolio and is designed for use in demanding electronic applications where reliable energy storage and filtering are essential. Multilayer ceramic capacitors (MLCCs) like this component serve as fundamental building blocks in modern electronics. Their primary function is to store and release electrical energy, filter noise from power supplies, couple or decouple signals between circuit stages, and stabilize voltage in various applications. The ceramic dielectric material used in these capacitors provides excellent electrical properties in a compact form factor, making them ideal for space-constrained designs. The part number designation 12105C184KAT4A indicates specific characteristics within AVX's naming convention. The "12105" prefix typically relates to the physical package size and series classification. The "C" designation generally denotes the ceramic composition and dielectric characteristics, while the "184K" segment provides information about capacitance value and tolerance class. The "AT4A" suffix indicates the specific termination and packaging format, suggesting lead-free construction—a requirement in many modern industrial and consumer applications due to environmental regulations. Engineers commonly specify AVX multilayer ceramic capacitors in industrial control systems, telecommunications equipment, power management circuits, automotive electronics, and various consumer and commercial devices. These components are particularly valued in applications requiring high volumetric efficiency, low equivalent series resistance, and stable performance across operating temperature ranges. The multilayer construction of this capacitor provides several advantages over single-layer alternatives. The multiple internal ceramic layers allow manufacturers to achieve higher capacitance values in smaller packages, reducing PCB real estate requirements. This design also typically offers improved frequency response characteristics and lower parasitic inductance compared to some alternative technologies. When selecting this specific part number, engineers would typically choose it based on requirements including the capacitance value, voltage rating, temperature stability characteristics, package size constraints, and reliability standards needed for their application. AVX's multilayer ceramic capacitors are designed to meet rigorous industrial standards and have proven reliability records in mission-critical applications. This component represents a standard choice for designers who need proven performance from an established manufacturer in a widely-used package format. Its availability through multiple distribution channels makes it a practical selection for both prototype development and high-volume production runs.
