CL21B102KECSNNC

The CL21B102KECSNNC is a film capacitor manufactured by Samsung, representing a reliable component choice for general-purpose filtering and coupling applications in electronic equipment. This part belongs to Samsung's established line of polyester film capacitors, which are widely used across industrial control systems, consumer electronics, power supplies, and telecommunications equipment. Film capacitors like this model are constructed with a dielectric film material that provides stable performance across a wide range of operating conditions. The "CL21B" designation indicates this is a compact radial-lead capacitor designed for through-hole PCB mounting, making it suitable for both automated assembly and manual installation in industrial production environments. The radial lead configuration allows for straightforward placement in standard PCB layouts where space efficiency and reliable mechanical attachment are important. Samsung's CL21B series capacitors are specified for general industrial and consumer applications where moderate performance requirements and cost-effectiveness are balanced considerations. These components are commonly selected for AC filtering in power supplies, signal coupling between amplifier stages, and general-purpose energy storage applications. The film dielectric provides inherent safety characteristics including self-healing properties, which help maintain functionality even after minor electrical stress. Engineers typically specify this particular part number when designing circuits that require a standard capacitor with proven reliability in moderate-performance applications. The CL21B series has established compatibility with standard PCB assembly processes and fits well within conventional component libraries used in industrial equipment design. This familiarity and proven track record across many installations make it a pragmatic choice for OEM and contract manufacturers seeking components with predictable sourcing and consistent performance. The compact radial package of the CL21B series makes it space-efficient compared to some alternative film capacitor designs, while maintaining the electrical stability that film dielectrics are known for. This balance between size, cost, and performance has contributed to the series' adoption across decades of industrial equipment design. For applications requiring certification documentation, specific electrical parameters, or integration into complex circuit designs, consulting the manufacturer's technical specifications is recommended. The CL21B series' long production history means this component integrates readily into established designs and serves as a reliable replacement option in equipment maintenance and upgrade scenarios.
