CL21A225KAFNNNG

The CL21A225KAFNNNG is a multilayer ceramic capacitor (MLCC) manufactured by Samsung, part of the CL21 series. This is a general-purpose ceramic capacitor designed for widespread use in consumer electronics, industrial control systems, telecommunications equipment, and automotive applications. Multilayer ceramic capacitors are among the most commonly used passive components in modern electronics due to their compact size, reliability, and cost-effectiveness. The CL21A series represents Samsung's offering in the popular 0805 package size (imperial designation), which measures approximately 2.0mm × 1.25mm. This small footprint makes it ideal for high-density PCB designs where space constraints are a priority, particularly in surface-mount assembly applications. The "A" designation in the part number indicates this capacitor operates across a broad temperature range typical for industrial and commercial-grade components. The CL21 series is known for stable capacitance values and low equivalent series resistance (ESR), making these capacitors suitable for decoupling, filtering, and coupling applications in power supplies, audio circuits, and signal processing stages. The specific capacitance value and voltage rating for this part can be determined from the full part number coding system, though engineers should verify exact specifications for their application requirements. Samsung's CL21A series generally offers competitive performance in terms of reliability and consistency, with capacitors in this family experiencing low failure rates when used within their rated specifications. Engineers might choose the CL21A225KAFNNNG over alternative capacitors for several reasons. Samsung MLCCs maintain tight tolerances and stable performance across temperature variations, which is critical in precision circuits. The 0805 package size represents an optimal balance between component miniaturization and ease of handling during assembly. Additionally, as a Samsung product, this capacitor benefits from established supply chain presence and consistent manufacturing quality across production runs. This component is particularly common in consumer product designs requiring multiple decoupling capacitors, in industrial automation controllers, in DC-DC converter circuits, and in radio frequency applications where filtering is essential. The CL21A series' reputation for reliability makes it a preferred choice in designs where component replacement costs or field service logistics present significant concerns. For applications requiring confirmation of exact electrical characteristics, including capacitance value, rated voltage, tolerance class, or operating temperature range, consulting the manufacturer's technical documentation is essential to ensure the part meets specific design requirements.
