CL21A105KOFNNNG

The CL21A105KOFNNNG is a multilayer ceramic capacitor (MLCC) manufactured by Samsung, representing a reliable choice for general-purpose filtering and coupling applications across industrial and consumer electronics. This component belongs to Samsung's established ceramic capacitor family, designed to meet the performance requirements of mainstream electronic assemblies where cost-effectiveness and proven reliability are priorities. Multilayer ceramic capacitors like this unit function as energy storage and signal conditioning elements in circuit design. They are commonly specified for power supply filtering, noise decoupling, signal coupling and decoupling, and transient suppression across DC and AC applications. The compact package footprint typical of this series makes it well-suited for space-constrained designs while maintaining adequate performance for standard industrial applications. The part number structure indicates this capacitor features a surface-mount package format, which is standard for modern PCB assembly. This enables automated placement and reflow soldering, reducing manufacturing cost and improving reproducibility compared to through-hole alternatives. The package is engineered for standard industrial temperature ranges and is compatible with lead-free soldering processes. Engineers typically specify Samsung MLCCs of this class when designing cost-sensitive applications that do not demand exotic characteristics or extreme operating conditions. The manufacturer's broad production volume and established supply chain make these capacitors readily accessible for both prototype development and high-volume production runs. Samsung's quality reputation and consistency in this commodity component category provides confidence in long-term device reliability. Compared to alternatives, this specific part represents a balance between performance, cost, and availability. While specialty capacitors offer enhanced temperature stability, higher voltage ratings, or tighter tolerances, the CL21A105KOFNNNG serves applications where general-purpose performance suffices. Its prevalence in industrial design means engineers often have prior experience with the part's behavior and characteristics, reducing design validation risk. Common application contexts include power management circuits, audio equipment, test and measurement instruments, industrial control systems, and auxiliary electronics within larger assemblies. The part's long production history suggests stable manufacturing processes and consistent quality metrics across production lots. For exact electrical specifications, operating temperature ranges, and detailed performance curves, engineers should consult the official Samsung component datasheet. This ensures that the selected capacitor meets all specific circuit requirements, including voltage derating, frequency response, and environmental constraints relevant to the intended application environment.
