12103C474MAT4A

The AVX 12103C474MAT4A is a multilayer ceramic capacitor (MLCC) designed for general-purpose filtering, coupling, and decoupling applications across industrial and consumer electronics. As a component in AVX's established 1210 case size family, this capacitor offers a standardized solution for circuit designers requiring reliable energy storage and signal conditioning in compact form factors. Multilayer ceramic capacitors like this part are fundamental building blocks in modern electronic assemblies. They are widely used in power supply circuits for noise filtering, in signal paths for AC coupling, and across digital logic boards for power distribution decoupling. The 1210 package designation indicates a surface-mount device measuring 12.7mm by 10.2mm, making it suitable for high-density PCB layouts while remaining large enough for manual inspection and rework when necessary. AVX is recognized for manufacturing MLCCs with consistent quality and reliable performance across commercial and industrial temperature ranges. Capacitors in this family typically exhibit stable capacitance over the operating temperature window, low equivalent series resistance (ESR), and low equivalent series inductance (ESL)—characteristics that make them suitable for both low-frequency filtering and higher-frequency decoupling tasks. The multilayer construction provides high capacitance density, allowing designers to achieve substantial capacitance values within a modest footprint. The specific capacitor code embedded in this part number indicates a particular capacitance value and voltage rating within AVX's product matrix. Engineers selecting this exact part typically do so when a specific capacitance requirement matches the specifications of this device, when the voltage class is appropriate for their circuit design, or when qualification documentation or supply chain commitments favor this particular AVX offering over functionally equivalent alternatives. This capacitor would be specified in applications ranging from industrial control electronics and instrumentation to telecommunications equipment and automotive systems. In power management circuits, MLCCs of this size serve as bulk or intermediate filtering elements. In digital circuits, they provide local charge storage near integrated circuits to maintain stable power delivery during transient current demands. The 1210 package remains a popular choice in modern design because it balances practicality across manufacturing, testing, and field service considerations. Its widespread adoption means design engineers have extensive reference designs and application notes available, reducing development risk and accelerating time-to-market for new products. For precise electrical performance parameters, recommended operating conditions, and reliability data specific to this part, consulting the manufacturer's published technical documentation is essential for proper circuit integration and long-term reliability assurance.
