CL21B104KOANNNC

The CL21B104KOANNNC is a multilayer ceramic capacitor (MLCC) manufactured by Samsung, belonging to the CL21 series of general-purpose film and ceramic capacitors widely used in electronics manufacturing and industrial applications. This component represents a standard choice for coupling, decoupling, and filtering functions across a broad range of consumer, industrial, and commercial electronic equipment. Multilayer ceramic capacitors like this part are fundamental building blocks in modern circuit design. They provide compact energy storage and signal coupling capabilities in a small package footprint, making them ideal for space-constrained applications where board real estate is at a premium. The CL21 series is recognized as a reliable, cost-effective option for applications that do not require specialized performance characteristics such as extremely high voltage ratings, extended temperature ranges, or precision tolerance matching. This particular part is commonly specified in power supply circuits, audio equipment, telecommunications hardware, computer peripherals, and general industrial control systems. Engineers select MLCCs from this series when designing boards that operate in standard environmental conditions and require stable performance across typical operating temperature ranges. The component's ceramic dielectric material provides good frequency response characteristics, making it suitable for both DC and AC applications across a wide frequency spectrum. The CL21 designation indicates a specific package and performance class within Samsung's capacitor portfolio. Parts in this series are designed to meet international standards for reliability and performance in mass-production environments. They offer a balance between cost-effectiveness and functional reliability, which has made them a standard choice for decades in electronics manufacturing. Engineers might specify the CL21B104KOANNNC over alternative capacitors when they require a proven, readily available component with established supply chains and well-understood performance characteristics. The Samsung brand backing provides additional confidence in manufacturing consistency and long-term availability, which is critical for products with extended lifecycles or high production volumes. Additionally, the extensive field history of this series means design teams can reference established application notes and proven circuit implementations, reducing development risk and time-to-market. For applications requiring extreme precision, specialized dielectric properties, or operation in harsh environmental conditions, designers would typically look toward alternative capacitor families with enhanced specifications. However, for the vast majority of standard industrial and commercial electronics applications, components from this series provide a reliable, economical solution that continues to be specified in new designs and supported in production environments worldwide.
