CL05C100DB5NNNC

The CL05C100DB5NNNC is a multilayer ceramic capacitor (MLCC) manufactured by Samsung, belonging to the CL series of chip capacitors designed for general-purpose electronics applications. This component is housed in a 0402 package, one of the most widely used surface-mount form factors in modern PCB assembly, making it suitable for space-constrained consumer and industrial electronics. Multilayer ceramic capacitors like this part function as energy storage and filtering elements in electronic circuits. They are used to smooth voltage ripple, decouple power supply noise, block DC signals while passing AC signals, and provide high-frequency filtering near integrated circuits. The CL series represents Samsung's mainstream offering for applications where standard performance and cost-effectiveness are priorities. The 0402 package size makes this capacitor ideal for compact electronic devices where board space is at a premium. Despite its small footprint, the part delivers reliable capacitive performance across a broad range of operating conditions. Engineers frequently specify MLCCs in this package for smartphone circuits, wearable electronics, automotive infotainment systems, industrial control boards, and IoT devices where miniaturization is essential. Engineers might select the CL05C100DB5NNNC specifically when they need a proven, high-volume component from a reputable manufacturer that offers excellent cost-to-performance ratio. Samsung's CL series capacitors are known for consistent quality and wide availability, which reduces supply chain risk in production environments. The part's designation indicates it is suited for standard temperature range applications found in most commercial and light industrial equipment. The 0402 package size also enables automated pick-and-place assembly and reflow soldering using standard SMT processes, making manufacturing simpler and more cost-effective than larger alternatives. This part would typically be used in multiple locations on a single board — for instance, as decoupling capacitors near microcontrollers, analog-to-digital converters, or voltage regulators, where multiple identical units provide comprehensive power supply filtering. For applications requiring extended temperature ranges, specialized dielectric materials, or higher voltage ratings, alternative parts within Samsung's capacitor portfolio or from competing manufacturers may be more appropriate. However, for general-purpose filtering and decoupling in standard commercial electronics, the CL05C100DB5NNNC represents a reliable, economical choice that has proven itself across millions of deployed devices.
