CL43B474JEFNNNS

The CL43B474JEFNNNS is a multilayer ceramic capacitor (MLCC) manufactured by Samsung, designed for use in a wide range of electronic applications requiring reliable energy storage and signal filtering. This component belongs to the CL series family, which represents Samsung's established line of general-purpose ceramic capacitors widely adopted in consumer electronics, telecommunications, industrial control systems, and automotive applications. Multilayer ceramic capacitors like this part function as passive components that store electrical charge and filter unwanted frequency components from circuits. They are essential building blocks in power supply filtering, decoupling networks, signal conditioning, and timing circuits across virtually all modern electronic equipment. The compact size and high volumetric efficiency of MLCCs make them ideal for space-constrained applications where multiple capacitors are needed in close proximity. The part number coding indicates this is a surface-mount device with a standard ceramic package form factor. Samsung's CL series capacitors are known for consistent performance, excellent reliability, and cost-effectiveness, making them a popular choice in high-volume manufacturing environments. These capacitors are typically specified where stable capacitance across operating temperature ranges and extended product lifecycles are important considerations. Engineers select specific MLCC part numbers based on several critical factors: the required capacitance value, voltage rating, temperature coefficient characteristics, physical package size constraints, and reliability requirements of the end application. The CL43B474JEFNNNS designation encodes these specifications in a standardized format that allows design engineers to quickly identify compatible alternatives and verify specifications against circuit design requirements. Samsung's ceramic capacitors in this series are manufactured using advanced multilayer techniques that provide high capacitance density while maintaining low equivalent series resistance (ESR) and excellent frequency response characteristics. This makes them suitable for applications ranging from simple DC blocking and coupling functions to more demanding high-frequency filtering and decoupling requirements in modern digital systems. The CL series is particularly valued in industrial and professional equipment design where component traceability, consistent manufacturing quality, and long-term availability are essential. Equipment manufacturers often specify these capacitors for critical filtering and stabilization functions where capacitor failure could compromise system reliability or safety. For engineers evaluating alternatives or selecting components for new designs, this part number represents a well-established solution from a major manufacturer with proven performance history in demanding applications. The specific package type and electrical characteristics encoded in this part number make it suitable for engineers designing systems with defined space and performance constraints.
