CL31B221KGFNNNG

The CL31B221KGFNNNG is a multilayer ceramic capacitor (MLCC) manufactured by Samsung, representing a reliable passive component widely used in industrial electronics, telecommunications equipment, and consumer device applications. This capacitor belongs to Samsung's established MLCC portfolio, which is known for consistent quality and performance across demanding environments. Multilayer ceramic capacitors like this part function as energy storage and filtering elements in electronic circuits. They are essential for decoupling, bypassing, noise suppression, and signal coupling applications. The CL31B series designates this as a surface-mount component, making it suitable for automated assembly processes and compact PCB layouts that characterize modern industrial electronics. The part number structure indicates specific electrical and physical characteristics. The "CL31B" prefix identifies the series type, while subsequent characters encode the capacitance value, voltage rating, tolerance, temperature coefficient, and packaging specifications. This particular variant uses a standard ceramic dielectric formulation optimized for general-purpose industrial applications where moderate temperature stability and cost-effectiveness are priorities. Engineers typically specify MLCCs from Samsung's established series like this one for applications requiring dependable performance without premium pricing. These capacitors appear frequently in power supply circuits, audio equipment, instrumentation, industrial control systems, and automotive electronics. Their small form factor and surface-mount design enable high-density circuit boards while maintaining electrical performance. The multilayer construction provides several advantages relevant to industrial specifications. Multiple ceramic layers increase effective capacitance in a compact package, reducing board space requirements. The ceramic dielectric material delivers stable capacitive properties across typical operating temperature ranges encountered in industrial environments. Samsung's manufacturing processes ensure consistent performance and low failure rates, which is critical for equipment designed for long service life. Key reasons engineers select this specific part include Samsung's reputation for quality consistency, the proven reliability of the CL31B series in established designs, and straightforward integration into existing supply chains. The standard form factor ensures compatibility with typical PCB assembly equipment, reducing manufacturing complexity and cost. For applications requiring higher voltage ratings, specialized temperature coefficients, or tighter tolerances, alternative capacitor series may be more suitable. However, for standard industrial decoupling, filtering, and coupling applications where the CL31B220 series characteristics align with circuit requirements, this Samsung capacitor represents an efficient and proven choice that balances performance, cost, and availability for design engineers and procurement specialists.
