12103C473MAT2A

# 12103C473MAT2A Product Description The 12103C473MAT2A is a multilayer ceramic capacitor (MLCC) manufactured by AVX, a recognized supplier of passive electronic components. This component belongs to the 1210 case size family, which is one of the most widely used footprints in modern electronics manufacturing. The "03" designation indicates this is part of AVX's 0603 metric equivalent series (approximately 3.2mm × 2.5mm), making it suitable for both surface-mount assembly on PCBs and integration into compact electronic devices where space efficiency is critical. Multilayer ceramic capacitors of this type serve essential functions in electronic circuits as energy storage and filtering elements. They are commonly used for decoupling and bypass applications, signal coupling and blocking, timing circuits, and noise suppression. The 1210 package size represents a popular middle ground between smaller capacitors and larger components, offering reasonable capacitance values while maintaining reasonable board space utilization—an important consideration in cost-sensitive production environments. The part number breakdown suggests this is a capacitor with a capacitance value in the 47nF range (the "473" coding indicates 47 followed by three zeros in picofarads, or 47,000pF/47nF). The "MAT2A" suffix denotes AVX's specific construction variant and electrical rating class. Capacitors with this nominal value are particularly common in RF circuits, digital logic power supply networks, and general-purpose analog applications where moderate capacitance values are required. Engineers typically specify the 12103C473MAT2A over alternatives based on several factors. AVX's reputation for consistency and reliability makes this part attractive for industrial applications requiring predictable component behavior across production batches. The 1210 package strikes a practical balance—larger than 0603 packages but smaller than 1812 or 1825 sizes, allowing designers to meet performance targets without excessive board area consumption. The specific material composition and construction indicated by the part number affects voltage rating, temperature stability, and aging characteristics, making it suitable for applications with particular environmental or reliability requirements. This component is widely found in telecommunications equipment, industrial control systems, automotive electronics, medical devices, and consumer electronics. Its standardization across the industry means it is readily available through multiple distribution channels and integrates easily into established manufacturing processes. For engineers designing circuits requiring stable, compact capacitive elements with proven long-term reliability, the 12103C473MAT2A represents a standard solution backed by a manufacturer with extensive experience in demanding applications.
