CL31C270JBCNBNC

The CL31C270JBCNBNC is a multilayer ceramic capacitor (MLCC) manufactured by Samsung, a leading producer of passive electronic components. This part belongs to the CL31 series, which represents a standard line of general-purpose ceramic capacitors widely used across industrial, commercial, and consumer electronics applications. Multilayer ceramic capacitors are fundamental passive components found in virtually every modern electronic circuit. They serve critical functions including signal coupling and decoupling, noise filtering, energy storage, and frequency tuning. The CL31 series specifically targets applications requiring reliable performance in compact form factors without demanding specialized temperature coefficients or extreme voltage ratings. Based on the part number nomenclature, this capacitor utilizes a 1206 package size, a standard surface-mount format measuring 3.2mm by 1.6mm. This size represents a practical balance between miniaturization and handling ease, making it ideal for dense circuit board layouts while remaining compatible with standard automated assembly equipment. The 1206 package is ubiquitous in modern PCB design and offers excellent thermal characteristics for heat dissipation during reflow soldering. The designation within the part number indicates this is likely a 27 nanofarad capacitance value with a J tolerance rating, meaning the actual capacitance falls within ±5% of the marked value. This tolerance class suits general-purpose filtering and coupling applications where tight tolerance control is unnecessary. Samsung's CL31 series capacitors typically operate across a broad temperature range suitable for most industrial environments, with X7R or similar dielectric characteristics providing stable capacitance across temperature and frequency variations. Engineers frequently specify Samsung CL31 series capacitors for applications including power supply filtering, high-speed digital circuits, audio signal conditioning, and RF filtering. The series' reputation for consistent quality and availability makes it a preferred choice in high-volume manufacturing environments. Designers may select this specific part over alternatives based on several factors: Samsung's manufacturing reliability and supply chain strength, proven performance in established circuit designs, compatibility with standard board assembly processes, and cost-effectiveness for non-critical applications. The CL31C270JBCNBNC is particularly suited for applications where component reliability matters but specialized performance characteristics are not required. Its broad applicability makes it a stock item in many design reference libraries and manufacturing environments, reducing qualification time for new product development.
