CL21B102KCANNWC

The CL21B102KCANNWC is a multilayer ceramic capacitor (MLCC) manufactured by Samsung, representing a reliable passive component widely used in modern electronic applications across industrial, consumer, and telecommunications sectors. This capacitor belongs to Samsung's CL21 series, which encompasses general-purpose film and ceramic capacitors designed for mainstream electronic assembly. The part's designation indicates it uses a compact surface-mount package suitable for automated production environments where space efficiency and consistent performance are required. MLCCs like this component are fundamental building blocks in circuit design, serving functions such as signal filtering, power supply decoupling, noise suppression, and AC coupling in various electronic systems. Engineers typically specify MLCCs in this family for applications requiring stable capacitance values across normal operating temperature ranges and reasonable voltage ratings. These capacitors are commonly found in consumer electronics, industrial control systems, power management circuits, RF and microwave applications, and automotive electronics where reliability and miniaturization are important. The CL21 series specifically targets applications where engineers need cost-effective, dependable passive components without requiring specialized high-voltage, high-temperature, or ultra-low-ESR characteristics. What distinguishes multilayer ceramic capacitors like the CL21B102KCANNWC from alternatives is their excellent volumetric efficiency—delivering significant capacitance in a very small footprint. This makes them ideal for space-constrained PCB layouts common in modern compact devices. Samsung's manufacturing quality ensures consistent electrical characteristics across production batches, which is particularly valuable in industrial applications where part-to-part variation must be minimized. The CL21 series is known for straightforward application and integration into standard manufacturing processes, as these components are compatible with conventional reflow soldering and automated pick-and-place assembly. This compatibility reduces manufacturing complexity and cost compared to components requiring specialized handling or assembly techniques. Engineers might choose this specific Samsung part over alternatives when they need a proven, widely-available capacitor with established supply chains, consistent quality documentation, and reliable performance in mainstream applications. The part's presence in established design libraries and its use across numerous commercial products makes it a low-risk specification choice. For applications requiring specialized performance—such as extremely high-frequency operation, ultra-wide temperature ranges, very high voltage ratings, or exceptional stability—engineers would typically evaluate alternative capacitor families with those specific capabilities. The CL21B102KCANNWC represents the type of fundamental component that enables efficient, cost-effective electronics manufacturing at scale.
