CL21B103JBANNNC

The CL21B103JBANNNC is a thin-film ceramic capacitor manufactured by Samsung, part of the CL21 series designed for general-purpose electronic applications. This component falls into the category of multilayer ceramic capacitors (MLCCs), which are among the most widely used passive components in modern electronics due to their small size, reliability, and cost-effectiveness. Thin-film ceramic capacitors like this model are constructed using multiple layers of ceramic dielectric material with interspersed metal electrodes, all contained within a compact surface-mount package. The "CL21" designation indicates this is a smaller format device suitable for space-constrained applications, making it ideal for compact consumer electronics, industrial control boards, telecommunications equipment, and automotive systems. The standardized package format ensures compatibility with automated assembly processes used in high-volume manufacturing. This capacitor type serves several critical functions in electronic circuits. Engineers commonly specify ceramic capacitors for bypass and decoupling applications, where they filter high-frequency noise from power supply rails to protect sensitive integrated circuits. They are also used in timing circuits, coupling and blocking applications, and as part of filter networks in analog and mixed-signal designs. The multilayer construction provides excellent high-frequency performance characteristics compared to older component technologies. The CL21 series from Samsung represents a reliable, proven family of components with established track records in demanding industrial and commercial applications. These capacitors are designed to meet rigorous quality and reliability standards, making them suitable for equipment requiring long operational lifespans. Engineers appreciate the consistency and predictability of Samsung's component lines, knowing that specified parts will perform reliably across production batches. Engineers might choose this specific part number for several practical reasons. The CL21 form factor offers an optimal balance between performance and space efficiency for many circuit designs. Samsung's manufacturing quality ensures minimal variation between units, supporting consistent circuit behavior. The part's established presence in supply chains means it has proven availability and competitive sourcing options compared to less common alternatives. When selecting a capacitor, engineers must consider package size, voltage rating, capacitance value, temperature characteristics, and frequency response requirements for their specific application. The CL21B103JBANNNC represents a standard solution where these parameters align with common engineering requirements across industrial and commercial electronics.
