12065C822KHT1A

The 12065C822KHT1A is a multilayer ceramic capacitor (MLCC) manufactured by AVX, one of the leading producers of passive electronic components. This part belongs to the 1206 case size family, which is a widely used surface-mount package measuring approximately 3.2mm by 1.6mm. Capacitors of this type are fundamental building blocks in modern electronic circuits, serving functions such as filtering, decoupling, energy storage, and signal coupling across countless applications. Multilayer ceramic capacitors are constructed from alternating layers of ceramic dielectric material and metal electrodes, all fired together into a monolithic structure. This construction enables high capacitance values in relatively small packages, making them ideal for space-constrained designs common in industrial and consumer electronics. The 1206 case size represents a popular middle ground between smaller packages like 0805 and larger ones, offering good handling characteristics during assembly while maintaining compact dimensions suitable for modern PCB layouts. The "C822" designation in this part number indicates a specific capacitance value within AVX's naming convention. MLLCs in this general family are typically used in applications requiring stable, reliable capacitance performance across temperature variations and operating conditions. Common applications include power supply filtering on digital control boards, decoupling networks in microprocessor circuits, timing circuits, and signal conditioning in industrial measurement equipment. They are also frequently found in automotive electronics, telecommunications infrastructure, and factory automation systems where reliability is critical. Engineers specify MLLCs like this part for several practical reasons. Surface-mount ceramic capacitors offer excellent high-frequency performance compared to older through-hole alternatives, with low equivalent series resistance and inductance. The 1206 package size provides a good balance between component cost and handling ease during manufacturing, reducing assembly complications that can arise with extremely small packages. AVX components are recognized for consistent quality and long-term availability, which matters significantly for industrial applications where supply chain continuity is essential. The multilayer construction also provides advantages in terms of voltage derating curves and temperature stability compared to single-layer ceramic designs. For engineers designing systems that must operate reliably in industrial environments—with temperature fluctuations, vibration, and demanding electrical conditions—specifying established component families from major manufacturers like AVX reduces risk and simplifies design qualification and long-term field support.
