CL21A225KOFNNNE

The CL21A225KOFNNNE is a multilayer ceramic capacitor manufactured by Samsung, designed for general-purpose applications across consumer electronics, industrial equipment, and telecommunications infrastructure. This component belongs to the CL21A series, which represents Samsung's established line of film and ceramic capacitors engineered for reliability and consistent electrical performance in demanding environments. As a ceramic capacitor, this component stores and releases electrical energy, functioning as a filtering element, noise suppressor, or timing component within circuits. Multilayer ceramic capacitors like this one are constructed from alternating layers of ceramic dielectric material and metal electrodes, a design that enables compact size while maintaining adequate capacitance in a small footprint. This architecture makes ceramic capacitors ideal for high-density circuit boards where space constraints are critical. The part number designation indicates this capacitor is housed in a surface-mount package, making it compatible with modern automated assembly processes used in manufacturing electronics. The CL21A series is commonly specified in applications requiring stable performance across temperature variations and extended operational lifespans, such as power supply circuits, signal coupling and decoupling applications, and EMI filtering stages. Engineers typically specify Samsung's CL21A series capacitors when reliability and consistency across production batches are priorities. Samsung's manufacturing standards ensure minimal variation between units, which is important in applications where component drift or failure could impact system performance or require costly field replacements. The series has established track records in both commercial and industrial segments, making it a trusted choice for designs requiring qualified components with proven performance history. Common application areas include switching power supplies, DC-DC converter circuits, audio amplifier stages, and various digital logic circuits requiring noise filtration. The compact form factor allows designers to meet space and weight requirements on modern circuit boards while maintaining the electrical performance needed for stable operation. When selecting this specific part number versus alternatives, engineers consider factors including package size compatibility with existing board designs, the established performance characteristics of the CL21A family within their application, and supply chain reliability. For applications where component performance consistency and historical field data are important, this Samsung capacitor represents a practical choice that balances cost, availability, and proven reliability across diverse industrial and consumer electronics applications.
