CL31B222KDCNFNC

The CL31B222KDCNFNC is a multilayer ceramic capacitor (MLCC) manufactured by Samsung, designed for general-purpose applications in electronic circuits requiring reliable energy storage and filtering capabilities. This component represents Samsung's established line of ceramic capacitors widely used across industrial, consumer, and telecommunications equipment. As a ceramic capacitor, this component functions as an electrical energy storage device that blocks direct current while allowing alternating current to pass. Its primary roles in circuit design include power supply filtering, signal coupling and decoupling, noise suppression, and voltage spike protection. Engineers rely on ceramic capacitors like this model for applications demanding compact form factors and cost-effective solutions without sacrificing performance. The part number structure indicates this capacitor belongs to Samsung's standard MLCC family, which is recognized throughout the electronics industry for consistent quality and availability. MLCCs are preferred in modern electronics because they offer high capacitance density in minimal physical space, making them ideal for densely populated printed circuit boards common in industrial control systems, power distribution modules, telecommunications infrastructure, automotive electronics, and consumer devices. This component is typically specified in circuits requiring general-purpose capacitance where the application doesn't demand specialized high-voltage, high-temperature, or extreme tolerance characteristics. Engineers might select this exact part number based on several factors: compatibility with existing designs already qualified with Samsung components, established supply chain relationships, proven performance history in similar applications, or specific board layout constraints that favor this particular package type and size. The MLCC category generally offers advantages including long shelf life, stable performance across normal operating temperature ranges, low equivalent series resistance suitable for high-frequency filtering, and excellent reliability when properly derated. These characteristics make ceramic capacitors the default choice for the vast majority of modern electronic equipment. Specifications for this part, including exact capacitance value, voltage rating, tolerance class, temperature coefficient, and package dimensions, should be verified against Samsung's technical documentation specific to this part number. Engineers designing or troubleshooting circuits should consult the complete datasheet to ensure proper application, particularly regarding voltage derating curves, frequency response characteristics, and thermal considerations. This component represents the type of fundamental building block common across industrial electronics manufacturing, suitable for designers seeking reliable, readily available capacitive solutions from a globally recognized manufacturer with established distribution channels.
