12063F104K4T2A

# Product Description The 12063F104K4T2A is a ceramic capacitor manufactured by AVX, one of the industry's established producers of passive electronic components. This part belongs to the general class of multilayer ceramic capacitors (MLCCs), which are among the most widely used capacitive components in modern electronics due to their compact size, reliability, and cost-effectiveness. Ceramic capacitors serve the fundamental function of storing electrical energy and are essential in virtually every electronic circuit. They are used for filtering, decoupling, coupling, timing, and energy storage applications across consumer electronics, industrial equipment, telecommunications infrastructure, automotive systems, and medical devices. Their small form factor and high volumetric efficiency make them particularly valuable in space-constrained designs. The part number format itself contains encoded information: the "12063" portion indicates a 1206-sized surface mount package, which measures approximately 3.2mm x 1.6mm. This is a standard metric package size widely used in modern PCB assembly. The "F" designation suggests this capacitor is specified for general-purpose industrial and commercial use. The "104" is a three-digit code representing the capacitance value in picofarads, while "K" indicates the tolerance class. The "4T2A" suffix denotes the specific AVX product line characteristics, including voltage rating and temperature coefficient classification. Capacitors in this size and category are typically rated for standard industrial voltage ranges, commonly 16V, 25V, 50V, or 100V depending on the specific variant. They generally operate across a standard temperature range suitable for most applications, though military and high-reliability variants extend these ranges further. Engineers and procurement professionals select this exact part number when they need a proven, widely-stocked ceramic capacitor from an established manufacturer with documented reliability in demanding applications. AVX capacitors are known for consistent quality and availability through major distribution channels, making them suitable for both prototype development and high-volume production runs. The 1206 package provides an optimal balance between component density and ease of assembly, hand-rework capability, and thermal performance compared to smaller alternatives. This component is typically specified in power supply circuits, signal conditioning paths, high-frequency filtering applications, and anywhere reliable decoupling and noise suppression are required. The combination of size, manufacturer reputation, and standardized availability makes this part a practical choice for industrial designers and engineers seeking dependable performance without excessive cost premium.
