CL21A475KPFNFNE

# CL21A475KPFNFNE - Samsung Film Capacitor The CL21A475KPFNFNE is a film capacitor manufactured by Samsung, representing a reliable choice for general-purpose AC and DC filtering applications across industrial and commercial electronics. This component belongs to Samsung's established line of polyester film capacitors, which are widely used in power supplies, audio equipment, instrumentation, and general signal conditioning circuits. Film capacitors like this part offer several inherent advantages over ceramic alternatives in many applications. They provide excellent stability across temperature ranges, consistent performance over the operational life of equipment, and low equivalent series resistance (ESR), making them suitable for circuits that require predictable capacitance retention and minimal distortion. The polyester film construction also delivers good mechanical robustness and resistance to voltage spikes, which is valuable in industrial environments where power quality may be inconsistent. The part number designation indicates this is a leaded component in a through-hole package format, making it compatible with conventional PCB assembly methods and suitable for designs where surface-mount technology isn't necessary or preferred. This package style remains common in industrial control boards, test equipment, and retrofit applications where maintainability and ease of hand-soldering are important considerations. Engineers typically specify film capacitors from this family when they need a cost-effective solution that balances performance with reliability. These capacitors are particularly common in AC power circuits, timing networks, coupling and decoupling stages, and filtering applications where moderate capacitance values are required. The polyester dielectric material provides better voltage linearity and temperature stability compared to standard ceramic capacitors, though at a different cost-performance point. The CL21A475KPFNFNE designation follows Samsung's standard marking convention, and the component can be readily identified and cross-referenced using this part number. For engineers working in product development, maintenance, or repair scenarios, this part serves as a direct replacement option when compatibility with existing circuit designs is required. This component is especially valuable in applications where long-term reliability and predictable behavior under varying load conditions matter more than miniaturization. Its through-hole package also simplifies prototype testing, troubleshooting, and field-level repairs in legacy equipment or custom industrial systems.
