CL21A225KACLNNC

# CL21A225KACLNNC - Samsung Film Capacitor The CL21A225KACLNNC is a film capacitor manufactured by Samsung, representing a core passive component used extensively in industrial electronics, power supplies, audio equipment, and consumer appliances. This component belongs to Samsung's established line of general-purpose film capacitors, which are valued for their reliability and consistent performance across diverse applications. Film capacitors like this model utilize a thin plastic film dielectric material, typically polypropylene or polyester, sandwiched between metal electrodes. This construction provides several inherent advantages over other capacitor technologies, including low equivalent series resistance (ESR), excellent frequency response characteristics, and robust handling of transient voltages. These properties make film capacitors the preferred choice for AC filtering, signal coupling, noise suppression, and energy storage applications where stability and longevity are critical. The part number format reveals this is a cylindrical through-hole component, which indicates it is mounted by inserting wire leads through holes in a printed circuit board. This radial or axial lead configuration is particularly common in industrial and retrofit applications where compatibility with existing PCB designs or hand-soldering processes is required. The through-hole form factor also allows for easier replacement and maintenance in field service scenarios compared to surface-mount alternatives. Samsung's film capacitor series is recognized for consistent dielectric strength and voltage rating performance, making these components suitable for use in both AC and DC circuits. They are commonly specified in power factor correction circuits, motor run applications, speaker crossover networks, and general-purpose smoothing or filtering stages in power supplies and electronic control systems. Engineers typically select this specific part when they need a dependable, general-purpose film capacitor with through-hole package compatibility, particularly in applications where the long operational life and low failure rate associated with film technology justify the component's size and cost versus electrolytic alternatives. The Samsung brand heritage in capacitor manufacturing provides confidence in production consistency and adherence to published specifications. This component is frequently stocked by distributors serving industrial maintenance, repair, and operations (MRO) segments, as well as manufacturers producing equipment requiring robust passive components. Its established design means cross-reference compatibility with earlier equipment designs is often straightforward, reducing redesign risk in maintenance or upgrade scenarios. For precise electrical specifications including capacitance value, voltage rating, tolerance, temperature characteristics, and frequency response, consultation of the manufacturer's technical documentation is recommended to ensure correct application in your specific circuit design.
