CL21A476MQYNNNE

The CL21A476MQYNNNE is a multilayer ceramic capacitor (MLCC) manufactured by Samsung, representing a reliable component choice for general-purpose filtering and coupling applications across industrial and consumer electronics. This capacitor belongs to Samsung's established family of surface-mount ceramic capacitors designed for broad compatibility with modern printed circuit board assembly processes. Multilayer ceramic capacitors like this model function as energy storage and filtering elements in electronic circuits. They suppress electrical noise, stabilize voltage supplies, and facilitate AC signal coupling between circuit stages. The ceramic dielectric material allows for compact size relative to capacitance value, making MLCCs ideal for space-constrained applications where reliability and performance consistency matter. The part designation suggests a surface-mount package format, indicating this capacitor is intended for automated assembly onto PCBs rather than through-hole mounting. This manufacturing approach supports high-volume production environments common in industrial electronics, telecommunications equipment, automotive systems, and consumer devices. Engineers frequently specify Samsung MLCCs in applications ranging from power supply filtering to RF signal conditioning. Engineers select this particular Samsung model based on several practical considerations. Samsung's MLCC products maintain consistent quality standards and stable manufacturing processes, which reduces supply chain variability. The capacitor's ceramic construction provides stable performance across typical operating temperature ranges encountered in industrial settings. Additionally, MLCCs offer superior frequency characteristics compared to electrolytic alternatives, making them suitable for high-speed digital circuits and switching power supplies where capacitive performance at elevated frequencies is important. The compact footprint characteristic of surface-mount MLCCs makes this component particularly valuable in modern electronic design where PCB real estate remains premium. Unlike larger electrolytic capacitors, MLCCs do not require special mounting considerations or polarization awareness during assembly, simplifying circuit design and reducing assembly errors. This capacitor class serves applications including decoupling and bypass filtering in microprocessor and digital logic circuits, energy storage in switched-mode power supplies, noise suppression in RF circuits, and signal coupling in audio and analog signal paths. Industrial control systems, measurement equipment, and telecommunications infrastructure commonly incorporate Samsung MLCCs due to their proven reliability and performance predictability. Engineers encountering this part number are typically designing or maintaining equipment requiring stable, compact capacitive filtering from a trusted manufacturer with consistent component availability and quality documentation across production batches. The Samsung brand reputation for ceramic capacitor manufacturing makes this a specified choice for applications where component reliability directly impacts system performance.
