CL31B475KBHNNNE

The CL31B475KBHNNNE is a multilayer ceramic capacitor (MLCC) manufactured by Samsung, part of Samsung's established family of general-purpose film and ceramic capacitors designed for industrial and commercial electronic applications. This component falls within the standard performance class of capacitors suitable for a broad range of circuit protection, filtering, and energy storage functions in power supplies, audio equipment, instrumentation, and consumer electronics. Multilayer ceramic capacitors like this model are constructed from multiple layers of ceramic dielectric material interleaved with metal electrodes, then stacked and fired into a single compact package. This construction method allows manufacturers to achieve relatively high capacitance values in a small physical footprint, making MLCCs extremely popular in space-constrained applications where engineers need reliable energy storage without significant board real estate commitment. The part designation "CL31B" identifies this as belonging to Samsung's standard general-purpose MLCC product line, with the "475" segment indicating the nominal capacitance value in the series. These capacitors are typically specified for applications requiring stable performance across moderate temperature ranges and at standard operating voltages common in consumer and industrial electronics. Engineers commonly select Samsung's MLCC products when they need proven reliability, consistent quality, and wide availability across multiple distributors and geographic regions. Typical applications for components in this family include decoupling and bypass filtering in digital circuits, energy storage in switched-mode power supplies, EMI suppression in power conversion stages, and general smoothing functions in analog and mixed-signal designs. The compact size and standardized package dimensions make them suitable for high-density PCB layouts, automated assembly processes, and cost-sensitive production environments where minimizing component size directly reduces manufacturing costs. What distinguishes this specific part number versus alternative capacitor options is the combination of Samsung's manufacturing reputation, the MLCC technology itself (which offers excellent frequency response characteristics compared to older electrolytic capacitor designs), and compatibility with existing engineering specifications that may reference this exact part. Engineers often specify MLCCs from established manufacturers when they have validated designs requiring predictable dielectric behavior, low equivalent series resistance, and minimal microphonic effects—particularly important in sensitive audio, measurement, or RF applications. For designers working on next-generation products or redesigns, this part offers a direct replacement path from prior Samsung MLCC selections, simplifying qualification and supply chain management while maintaining design continuity.
