CL21A106KPFNN5E

The CL21A106KPFNN5E is a multilayer ceramic capacitor (MLCC) manufactured by Samsung, representing a reliable and cost-effective passive component widely used in electronic circuits and industrial applications. This capacitor belongs to Samsung's CL series family, which is engineered for general-purpose use across consumer, commercial, and industrial electronics. Multilayer ceramic capacitors are fundamental building blocks in modern electronics, serving critical functions including energy storage, signal coupling, filtering, and noise suppression in power supply circuits, audio equipment, telecommunications hardware, and industrial control systems. The CL series is specifically designed for applications where moderate performance and compact packaging are required, making these capacitors popular choices for high-volume manufacturing and cost-sensitive designs. The "21" designation in the part number indicates a 1206 package size (3.2mm x 1.6mm), which represents a standard surface-mount footprint widely supported by automated assembly equipment. This package size offers a practical balance between component density and ease of handling, making it suitable for both dense PCB layouts and applications with moderate current-carrying requirements. The compact form factor allows engineers to minimize board space while maintaining accessibility for rework and repair operations. Samsung's CL series capacitors are manufactured using multilayer ceramic technology with X7R dielectric properties, a common classification that provides stable capacitance across a broad temperature range compared to less expensive alternatives. This characteristic makes the part suitable for applications exposed to varying environmental conditions, from consumer electronics operating near room temperature to industrial equipment experiencing moderate thermal fluctuations. Engineers typically specify this exact part number when designing circuits that require a general-purpose capacitor with proven reliability, wide availability, and compatibility with standard PCB assembly processes. The combination of established manufacturing processes, cost efficiency, and predictable performance characteristics makes the CL21A106KPFNN5E an appropriate choice for applications where premium performance capacitors are unnecessary. Additionally, Samsung's global distribution network and consistent quality standards help reduce supply chain risks for manufacturers planning long-term production runs. The part number designation follows Samsung's systematic naming convention, allowing engineers to quickly identify key characteristics including package size, dielectric type, and configuration. This standardization facilitates circuit design, procurement planning, and cross-reference documentation across engineering teams.
