CL21B102KBANNND

# CL21B102KBANNND - Samsung Film Capacitor The CL21B102KBANNND is a film capacitor manufactured by Samsung, representing a widely-used component in industrial electronics and consumer device applications. Film capacitors are passive components constructed with thin plastic film dielectrics and metal electrodes, offering reliable performance in circuits requiring stable capacitance values and low leakage characteristics. This particular part belongs to Samsung's CL21 series, which encompasses general-purpose film capacitors designed for mainstream industrial applications. These capacitors are typically utilized in power supply circuits, audio equipment, motor control systems, and various AC coupling applications where consistent performance and cost-effectiveness are priorities. Film capacitors like the CL21B102KBANNND are valued for their inherent reliability and low failure rates compared to some alternative technologies. They exhibit excellent frequency characteristics and minimal temperature drift, making them suitable for applications spanning standard operating temperature ranges. The stable capacitance behavior of film dielectrics is particularly advantageous in circuits where precision and long-term performance stability matter. The part designation itself conveys important information about its electrical classification. The CL21 designation indicates the series and physical package size, while the alphanumeric suffix provides additional specification details regarding capacitance value, voltage rating, tolerance class, and lead configuration. This standardized naming convention allows engineers to quickly identify compatible alternatives within Samsung's capacitor portfolio. Engineers typically specify the CL21B102KBANNND when they need a dependable film capacitor for standard industrial applications where the part's specific characteristics align with circuit requirements. Film capacitors in this series find use in EMI filtering, AC line applications, DC bus filtering in power electronics, and signal coupling circuits. Their construction provides inherent safety characteristics, as film capacitors are self-healing and demonstrate graceful degradation patterns rather than catastrophic failure modes. The choice of this specific part over alternatives often depends on matching the required capacitance value, voltage rating, and physical dimensions to available board space. Original equipment manufacturers and system integrators frequently standardize on proven components like Samsung's CL21 series to streamline supply chain management and reduce qualification costs across multiple production platforms. For applications requiring flame-rated or specialized environmental certifications, or where specific voltage and capacitance combinations are necessary, consulting detailed component specifications ensures proper selection and reliable long-term circuit performance.
