CL31C220JBNC

The CL31C220JBNC is a multilayer ceramic capacitor (MLCC) manufactured by Samsung, designed for general-purpose applications across industrial electronics, consumer devices, and telecommunications equipment. This component belongs to the CL31 series, which represents Samsung's established family of reliable ceramic capacitors widely used in mainstream electronic assemblies. Multilayer ceramic capacitors function as energy storage and filtering elements in circuits. They are essential for smoothing power supply ripple, coupling and decoupling signals, bypassing high-frequency noise, and stabilizing voltage rails in digital and analog circuits. The CL31 series serves applications where consistent performance and cost-effectiveness are priorities rather than extreme size reduction or specialized electrical properties. The part number structure indicates specific characteristics. The "CL31" designation identifies this as a standard MLCC from Samsung's established portfolio. These capacitors typically feature a conventional surface-mount package suitable for automated assembly on printed circuit boards. The construction uses multiple layers of ceramic dielectric material with interleaved metallic electrodes, a proven technology that delivers stable capacitance across normal operating conditions. Engineers commonly specify CL31 series capacitors in power distribution networks, audio circuits, switching power supplies, and general signal conditioning applications. The series is particularly valued in designs where proven reliability, reasonable performance tolerances, and broad availability are important factors. These capacitors work well in environments requiring moderate voltage and temperature stability without specialized requirements for extremely high Q-factor performance or ultraminiaturization. Compared to alternatives, the CL31 series offers a practical balance for industrial and commercial applications. While specialized capacitor families exist for high-reliability military use, extreme temperature ranges, or minimal board space, the CL31 addresses the majority of standard engineering requirements. This broad applicability, combined with Samsung's manufacturing scale and distribution, makes these components accessible and cost-competitive for volume production. The MLCC technology in this part provides several inherent advantages: small physical footprint relative to older film or electrolytic capacitor technology, good high-frequency performance, excellent reliability in stable environments, and compatibility with standard surface-mount assembly processes. These characteristics have made MLCCs the dominant capacitor technology across most industrial electronics sectors. For engineers evaluating this component, it represents a dependable choice for applications where standard electrical performance, proven field reliability, and inventory availability are the primary selection criteria.
