22251C155MAT2A

The AVX 22251C155MAT2A is a multilayer ceramic capacitor (MLCC) designed for general-purpose decoupling, filtering, and energy storage applications in industrial and commercial electronics. As a component from AVX's established capacitor portfolio, this part serves as a reliable choice for circuit designers working with standard PCB-level power distribution and signal conditioning requirements. Multilayer ceramic capacitors like this unit are among the most widely used passive components in modern electronics. They function by storing and releasing electrical charge across their ceramic dielectric material, making them essential for smoothing voltage ripple, blocking DC while passing AC signals, and providing localized charge storage near high-speed digital and analog circuits. The compact package format enables high component density on circuit boards while maintaining adequate electrical performance for mainstream industrial applications. This particular part carries the AVX brand designation, which indicates compliance with established manufacturing standards and consistent quality control. AVX capacitors are used across industrial automation, power supplies, telecommunications infrastructure, test and measurement equipment, and consumer electronics sectors where reliable performance and proven supply chain continuity are important factors. The alphanumeric designation "22251C155MAT2A" encodes information about the capacitor's electrical and mechanical specifications, including its capacitance value, voltage rating, temperature characteristics, and physical package format. The "MAT" portion of the part number typically indicates a specific package size and termination style optimized for standard PCB assembly processes. Engineers and procurement teams use these designations to ensure compatibility with existing circuit designs and manufacturing workflows. Industrial buyers often specify multilayer ceramic capacitors for applications requiring cost-effectiveness, compact form factors, and predictable performance across the operating temperature range. Compared to electrolytic or tantalum alternatives, MLCCs offer lower ESR (equivalent series resistance) at higher frequencies, superior frequency response for AC filtering, and greater reliability in harsh environments where temperature and humidity fluctuations are common. The specific configuration encoded in this part number makes it suitable for integration into power management circuits, analog signal processing stages, and digital logic supply rails where filtering and stabilization of supply voltages directly impact system performance and product lifespan. Engineers select this exact part number when their design requirements align with the electrical characteristics, package dimensions, and environmental specifications it provides, and when they need continuity with established component selections across multiple product generations or manufacturing facilities.
