12105C104JAT4A

The AVX 12105C104JAT4A is a multilayer ceramic capacitor (MLCC) from AVX's established capacitor product line. This component is designed for general-purpose energy storage, filtering, and coupling applications across a wide range of industrial and commercial electronic equipment. Multilayer ceramic capacitors like this one are among the most widely used passive components in modern electronics. They provide compact size, high reliability, and cost-effectiveness compared to many alternative capacitor technologies. The 12105C series designation indicates this is a standard format MLCC with industry-recognized dimensions that allow for consistent PCB layout and assembly across different designs. The "104" designation in the part number refers to the capacitance value using standard component marking conventions. Capacitors in this family are commonly used in power supply circuits, signal filtering on digital and analog boards, decoupling applications near integrated circuits, and as part of tuning or compensation networks. Engineers frequently specify MLCCs like the 12105C104JAT4A in applications requiring stable performance across temperature ranges and long operational life. AVX is a recognized manufacturer of ceramic capacitors with decades of experience producing components for telecommunications, military, aerospace, automotive, and industrial sectors. The company maintains consistent quality standards and offers broad product families to serve different voltage and capacitance requirements. This particular part number's "JAT4A" suffix indicates specific termination and packaging details that define how the component is mounted and processed. The designation suggests this is a standard lead-free termination suitable for modern manufacturing processes and environmental compliance requirements. Engineers selecting this exact part typically need to match specific footprint requirements, termination specifications, or qualification standards that may apply to their equipment or application. Common reasons to specify this particular part include matching existing board designs, meeting qualification requirements for specific industries, ensuring compatibility with established supply chains, or fulfilling requirements for temperature stability and long-term reliability. The standardized nature of MLCCs means this component is suitable for design engineers working across consumer, industrial, and specialized equipment manufacturing. For applications involving high-frequency circuits, high-voltage systems, or extreme temperature environments, engineers would typically need to evaluate this component alongside alternatives or specify other capacitor types. However, for standard industrial and commercial applications where moderate voltage and temperature performance are adequate, multilayer ceramic capacitors remain the default choice for most circuit designers.
