12065F104M4T2A

The AVX 12065F104M4T2A is a surface-mount multilayer ceramic capacitor (MLCC) designed for general-purpose applications in industrial and commercial electronics. This component belongs to the 1206 package family, one of the most widely used capacitor formats in modern PCB design due to its balance of compact footprint and ease of assembly with standard manufacturing equipment. Multilayer ceramic capacitors like this model are fundamental building blocks in circuit design, serving functions such as decoupling, filtering, coupling, and energy storage across power supply circuits, signal conditioning networks, and RF applications. The 1206 package size (approximately 3.2mm x 1.6mm) makes it suitable for space-constrained designs while remaining large enough for reliable soldering and rework without specialized handling. The "F" designation in AVX's naming convention typically indicates a standard dielectric material formulation optimized for capacitance stability and general-purpose use. This type of capacitor is commonly specified in consumer electronics, industrial control systems, telecommunications equipment, automotive electronics, and medical devices where moderate performance requirements and cost efficiency are priorities. The 4T2A suffix refers to AVX's specific termination and packaging configuration, indicating RoHS-compliant construction with standard nickel-barrier termination suitable for lead-free soldering processes. This is particularly important for engineers working in markets or applications where RoHS compliance is mandatory or preferred. Engineers typically specify this exact part number when designing circuits that require a proven, widely-available capacitor with established supply chain reliability. The 1206 package strikes an optimal balance for many applications: it's larger than 0603 or 0402 packages, offering better reliability and easier manual rework if needed, while remaining significantly smaller than through-hole or larger surface-mount alternatives. This makes it the default choice for many industrial OEMs and contract manufacturers. The component's performance characteristics are suitable for applications operating at typical industrial voltage levels and temperature ranges. Its multilayer ceramic construction provides stable capacitance across frequency ranges from DC through RF, making it versatile for both low-frequency filtering and higher-frequency decoupling applications. Designers frequently stock this part number as a standard capacitor for general use, reducing design complexity by minimizing the number of unique part numbers in their bill of materials. The combination of AVX's manufacturing reputation, the commonality of the 1206 package, and the widespread compatibility of this capacitor type across PCB assembly facilities makes it a dependable choice for both prototype and production applications.
