CL03C101JB3ANNC

The CL03C101JB3ANNC is a multilayer ceramic capacitor (MLCC) manufactured by Samsung, belonging to the general-purpose film and ceramic capacitor category widely used in modern electronics. This component represents a standard passive element essential to countless industrial, consumer, and automotive applications where energy storage, filtering, and signal coupling are required. Multilayer ceramic capacitors like this Samsung part are among the most commonly specified passive components in electronics manufacturing. They are constructed from alternating layers of ceramic dielectric material and metal electrodes, compressed into a small package that provides reliable capacitance in a compact footprint. The CL series designation indicates Samsung's commodity-grade offering, designed for cost-sensitive applications where performance requirements are moderate and standardized. The part number structure suggests a 0603 package size (metric designation 1608), which represents a widely standardized surface-mount format measuring approximately 1.6mm × 0.8mm. This size sits in the middle ground of the MLCC spectrum—larger than 0402 packages but smaller than 1206 packages—making it suitable for modern PCB designs where space efficiency matters but component accessibility during assembly and repair remains practical. The "101" designation within the part number indicates a nominal capacitance value in the picofarad range, typical for decoupling and high-frequency filtering applications. Engineers specify Samsung MLCCs for several practical reasons. Samsung maintains stringent quality control and consistent manufacturing processes across large production volumes, reducing the risk of supply chain variability that can plague smaller manufacturers. The company's broad distribution network ensures availability across global supply chains. Additionally, Samsung capacitors are characterized by stable performance across temperature ranges and voltage conditions relevant to industrial applications, making them suitable for equipment operating in variable environmental conditions. Common application areas include PCB decoupling near integrated circuits, RF filtering in communication systems, power supply filtering, signal conditioning in measurement equipment, and general-purpose energy storage in control systems. The relatively small physical size makes these capacitors ideal for modern compact designs while their ceramic construction provides excellent frequency response characteristics, particularly important in high-speed digital and RF applications. When selecting this specific part, engineers often consider its proven reliability, established design precedent across thousands of existing products, availability from multiple authorized distributors, and compatibility with standard reflow soldering processes. For industrial buyers, the combination of proven performance, cost-effectiveness, and supply reliability makes Samsung's CL-series ceramics a logical specification choice in applications where specialized high-performance capacitors are not required.
