0805YD474MAT2A

The 0805YD474MAT2A is a multilayer ceramic capacitor (MLCC) manufactured by AVX, one of the largest and most established capacitor manufacturers in the electronics industry. This component belongs to the 0805 package family, which refers to its physical dimensions of 0.08 by 0.05 inches (2.0 by 1.25 millimeters). The 0805 form factor is one of the most widely used surface-mount capacitor sizes in modern electronics, offering an optimal balance between board space efficiency and ease of handling in both manual and automated assembly processes. Multilayer ceramic capacitors like this unit are fundamental passive components found in virtually every category of electronic equipment. They serve multiple critical functions including power supply filtering, signal coupling and decoupling, noise suppression, and frequency tuning. The ceramic dielectric material used in these capacitors provides stable performance across a broad range of frequencies and environmental conditions, making them suitable for applications from DC blocking to high-frequency RF circuits. The "YD" designation in the part number indicates this capacitor belongs to AVX's standard general-purpose ceramic capacitor line, designed for reliable performance in mainstream industrial and consumer applications. The "474" portion of the part number encodes the capacitance value in picofarads using standard electronics notation. The "2A" suffix specifies the voltage rating and tolerance class, indicating this component is rated for relatively low voltage operation, making it ideal for modern low-voltage digital and analog circuits commonly found in consumer electronics, telecommunications equipment, and industrial control systems. Engineers typically specify the 0805YD474MAT2A when designing circuits that require stable, predictable capacitance in a compact package without premium performance requirements. Compared to other capacitor technologies, MLCCs offer superior frequency response, excellent temperature stability across typical operating ranges, extremely small leakage currents, and proven long-term reliability in high-volume production environments. The 0805 package specifically is preferred when PCB real estate is limited but component accessibility for repair or rework must be maintained. This capacitor finds common use in decoupling applications near integrated circuits, in filtering stages of power management circuits, and in impedance matching networks. Its ceramic construction means it exhibits minimal performance degradation over extended operational periods, making it suitable for both consumer products with three to five year lifecycles and industrial equipment designed for decades of service.
