CL21B102KDCNNNC

# CL21B102KDCNNNC Product Description The CL21B102KDCNNNC is a film capacitor manufactured by Samsung, designed for general-purpose applications in industrial electronics and power conditioning circuits. As a component in Samsung's established CL21 series, this capacitor represents a reliable choice for engineers requiring stable performance in demanding environments. Film capacitors like this part are constructed using a polymer or polyester film dielectric with metallic electrodes, offering inherent advantages in terms of self-healing properties and reliability. This construction method makes film capacitors particularly suitable for applications where component longevity and consistent electrical behavior are critical. The CL21 series typically serves applications ranging from consumer electronics to industrial control systems, where the capacitor must withstand varying operating conditions without premature failure. The part number structure indicates this is a standard non-polarized capacitor, meaning it can be installed in either direction within a circuit. This characteristic simplifies circuit board layout and reduces assembly errors during manufacturing. The standard through-hole or surface-mount package format associated with this series allows for straightforward integration into both legacy and modern PCB designs. Film capacitors from this series are commonly specified in filtering applications, noise suppression circuits, and DC coupling stages where low distortion and stable capacitance over time are required. Industrial equipment designers often select this type of component for power supply filtering, EMI suppression, and timing circuits where the predictable behavior of film technology provides advantages over ceramic alternatives. The construction and materials used in Samsung's CL21 series generally provide good temperature stability and low equivalent series resistance (ESR) across typical operating ranges. Engineers might choose the CL21B102KDCNNNC specifically when they need a proven film capacitor solution with Samsung's manufacturing quality in a compact, cost-effective package. The standardized part from an established manufacturer ensures consistent performance across production batches, simplifies inventory management, and provides confidence in long-term availability and reliability. This part number's continued presence in active distribution channels makes it an appropriate choice for both new equipment designs and replacement applications in existing systems. The component's suitability spans HVAC controls, instrumentation, telecommunications infrastructure, and general industrial power electronics where film capacitor technology is preferred over alternatives. For applications requiring detailed electrical parameters, component selection guidance, or application-specific recommendations, consulting technical documentation specific to your circuit requirements is advised.
