CL31C102JDFNNWE

The CL31C102JDFNNWE is a multilayer ceramic capacitor (MLCC) manufactured by Samsung, representing a widely-used passive component in modern electronics. This capacitor belongs to the CL31 series, which is designed for general-purpose applications requiring reliable energy storage and filtering across a broad range of consumer, industrial, and automotive electronics. Multilayer ceramic capacitors are fundamental building blocks in circuit design, serving critical functions such as power supply filtering, signal coupling and decoupling, noise suppression, and timing circuit stabilization. The CL31 series specifically targets applications where cost-effectiveness and compact form factor are priorities without sacrificing performance reliability. These capacitors are engineered to provide stable capacitance across operating conditions, making them suitable for both analog and digital circuit implementations. The "JDF" designation within this part number indicates a surface-mount ceramic capacitor with a 1206 package size (3.2mm x 1.6mm), one of the most common standardized dimensions in modern PCB assembly. This mid-range package size offers a practical balance between component density and ease of manual or automated handling during manufacturing. The 1206 footprint is widely supported across PCB design libraries and assembly equipment, reducing production complications and enabling rapid prototyping and volume manufacturing. Samsung's CL31 series MLCCs are recognized for consistent performance in industrial-grade applications. These capacitors maintain reliable operation across temperature variations and voltage stresses typical in embedded systems, industrial control boards, telecommunications equipment, and consumer electronics. The ceramic dielectric formulation provides good frequency response characteristics, making these components suitable for filtering applications ranging from low-frequency power supplies to higher-frequency RF circuits. Engineers typically specify this exact part when designing circuits that require a proven, readily-available capacitor with established supply chain presence. The combination of Samsung's quality reputation, the standardized 1206 package, and the CL31 series' proven field reliability across diverse applications makes this component an attractive choice for cost-conscious designs that cannot compromise on component availability or long-term performance consistency. The part's suitability for wave soldering and reflow processes, combined with its compatibility with standard manufacturing workflows, further reinforces its appeal in production environments where multiple assembly technologies may be employed. For engineers selecting discrete capacitors, the CL31C102JDFNNWE represents a dependable option where general-purpose filtering and coupling requirements are paramount.
