CL21A225KPFNNNF

The CL21A225KPFNNNF is a multilayer ceramic capacitor (MLCC) manufactured by Samsung, representing a reliable passive component widely used in electronic circuits across industrial and consumer applications. This capacitor belongs to the CL series family, which is engineered to meet demanding performance requirements in modern electronic equipment. Multilayer ceramic capacitors like this part are fundamental building blocks in circuit design, used for energy storage, filtering, decoupling, and signal coupling applications. They are particularly valued in power supply circuits, audio systems, RF applications, and general-purpose filtering where stable capacitance and low ESR (equivalent series resistance) characteristics are important. Engineers commonly specify MLCCs in switching power supplies, amplifiers, data acquisition systems, and telecommunications equipment. The CL21A designation indicates this capacitor uses a physical package size and construction optimized for compact mounting in modern PCB layouts. The "A" variant typically represents capacitors designed for general-purpose use with balanced performance characteristics across a range of operating conditions. Samsung's CL series MLCCs are manufactured using advanced dielectric materials and processes that provide consistent electrical performance and high reliability. Key reasons engineers select this specific part number include its proven reliability from a recognized manufacturer, standardized package dimensions that ensure compatibility with established PCB designs, and consistent performance characteristics that simplify circuit design and validation. The multilayer ceramic construction provides stable capacitance values across varying temperature ranges and bias conditions, which is critical in precision applications where capacitor drift could degrade circuit performance. This component is typically used in mid-range voltage applications common in industrial electronics, consumer devices, and telecommunications infrastructure. Its compact form factor makes it suitable for space-constrained designs while maintaining the electrical performance necessary for modern switching frequencies and signal processing circuits. The ceramic dielectric material used in this construction offers excellent frequency response characteristics, making it suitable for both DC filtering applications and higher-frequency signal processing. Engineers working with industrial control systems, test and measurement equipment, power distribution systems, and embedded electronics frequently encounter specifications calling for components from the CL series. The standardization of Samsung's MLCC product line across these part numbers ensures design flexibility and sourcing reliability across production runs. For engineers evaluating capacitor options, this part represents a mainstream choice that balances performance, size, cost-effectiveness, and supplier availability in the broader marketplace of passive components.
