CL21B104KCC5PNC

The CL21B104KCC5PNC is a multilayer ceramic capacitor (MLCC) manufactured by Samsung, part of the popular CL series designed for general-purpose applications in consumer and industrial electronics. This component represents a standard choice for circuit designers seeking reliable energy storage and signal coupling across a wide range of voltage and frequency conditions. Multilayer ceramic capacitors like this model are fundamental building blocks in modern electronics, serving critical functions including power supply filtering, signal coupling and decoupling, noise suppression, and timing circuit stabilization. The CL21B series designation indicates this capacitor belongs to Samsung's established lineup of surface-mount ceramic capacitors, widely adopted across industries for their consistency and proven field performance over decades of deployment. The part number coding reveals this capacitor uses Class B dielectric material, which provides stable capacitance characteristics across a moderate temperature operating range. This makes it suitable for applications where temperature stability matters but extreme performance across wide temperature extremes is not required. Class B ceramics are commonly selected for mainstream industrial equipment, telecommunications infrastructure, consumer appliances, automotive electronics, and general-purpose power conversion circuits where cost-effectiveness and reliable operation meet practical requirements. As a surface-mount component, the CL21B104KCC5PNC integrates easily into modern automated manufacturing processes, enabling high-volume production with consistent placement accuracy. This package style has become the industry standard for most contemporary electronic designs, replacing through-hole alternatives in the vast majority of applications. Engineers favor surface-mount capacitors for their compact footprint, enabling denser circuit layouts without sacrificing electrical performance. Engineers might specify this particular part when designing circuits that require a capacitor with predictable behavior in standard temperature environments, moderate voltage ratings appropriate for logic and mixed-signal circuits, and the established supply chain advantages that come with a popular Samsung part number. The CL21 footprint size offers a practical balance between component miniaturization and ease of board-level rework and repair, which remains important for industrial equipment servicing in the field. The CL series has earned widespread adoption because it delivers straightforward capacitive performance without premium pricing, making it the default choice for thousands of circuit designs. Whether serving in consumer power supplies, industrial control systems, or telecommunications equipment, this capacitor family provides the reliable filtering and coupling functionality that engineers have come to expect from established mainstream components.
