12105C105MAT2A

The AVX 12105C105MAT2A is a multilayer ceramic capacitor (MLCC) designed for general-purpose applications across industrial, consumer, and telecommunications equipment. This component belongs to AVX's established capacitor families and represents a common choice for circuit designers requiring reliable energy storage and filtering capabilities in compact form factors. Multilayer ceramic capacitors function as passive components that store electrical energy in an electric field between conductive plates separated by dielectric material. The 12105 designation indicates this part uses a surface-mount package format, making it suitable for modern automated assembly processes. The ceramic construction provides stable performance across temperature ranges typical for industrial environments, with relatively low equivalent series resistance (ESR) that makes these capacitors particularly useful for noise filtering and signal coupling applications. This capacitor would typically be specified in power supply circuits, decoupling networks near integrated circuits, timing circuits, and filter applications where compact size and cost-effectiveness are important design considerations. Engineers commonly use MLCCs like this model in consumer electronics, industrial control boards, automotive electronics, and telecommunications infrastructure where high-volume production justifies the use of surface-mount technology. The ceramic dielectric composition of this component provides several practical advantages. Ceramic capacitors offer excellent frequency response characteristics, making them suitable for both DC blocking and AC coupling tasks. They exhibit good stability over time and are less prone to the aging effects sometimes seen in other dielectric materials. The volumetric efficiency of ceramic technology means designers can achieve necessary capacitance values in minimal board space, which is critical in modern compact device designs. An engineer might select the AVX 12105C105MAT2A specifically because AVX is an established manufacturer with consistent quality standards and reliable supply chains. The part's designation suggests it meets specifications for industrial-grade applications where component reliability directly impacts system uptime. The surface-mount package accommodates high-speed assembly processes and wave soldering or reflow techniques, reducing manufacturing costs while maintaining quality. Additionally, the specific capacitance value this part number represents makes it a standard choice for common voltage regulation, EMI suppression, and frequency compensation roles. For designers working with AVX component families, standardizing on parts like this simplifies supply chain management, reduces qualification time, and leverages existing manufacturing and quality data. This component represents the type of fundamental building block upon which reliable electronic systems are constructed, particularly in applications where proven performance and cost efficiency matter more than specialized high-frequency or extreme environmental capabilities.
