CL05C3R3CB5NNNC

The CL05C3R3CB5NNNC is a multilayer ceramic capacitor (MLCC) manufactured by Samsung, representing a component fundamental to modern electronic circuit design. This part belongs to Samsung's established line of compact capacitors engineered for high-volume industrial and consumer applications requiring reliable energy storage, filtering, and signal coupling across diverse frequency ranges. Multilayer ceramic capacitors like this one serve as critical passive components in virtually every electronic device. They function to smooth voltage fluctuations, filter unwanted noise, decouple power supplies, and store electrical energy temporarily within circuits. The compact form factor makes them ideal for space-constrained applications where board real estate is premium, such as mobile devices, computing equipment, telecommunications infrastructure, automotive electronics, and industrial control systems. The "CL" designation identifies this as a Samsung MLCC, while the "05" in the part number indicates a 0402 package size—one of the most widely adopted SMD (surface-mount device) dimensions in the industry. This miniature footprint, approximately 1.0mm x 0.5mm, allows engineers to achieve high component density on printed circuit boards while maintaining manufacturability through standard automated assembly processes. The 0402 package is particularly prevalent in applications requiring compact designs without sacrificing performance or reliability. The character sequence "C3R3" embedded in the part number provides information about the capacitance value and voltage rating, while additional characters denote the specific dielectric material, tolerance class, and temperature coefficient. Samsung's MLCC portfolio spans multiple dielectric types optimized for different performance priorities—whether that means stable capacitance across temperature ranges, high volumetric efficiency, or specialized frequency response characteristics. Engineers typically specify Samsung MLLCs for their consistent quality, proven manufacturing processes, and availability across global supply chains. The brand's reputation for reliability and performance makes these capacitors preferred choices in quality-critical applications where component failure could compromise system function. Industries such as automotive, aerospace, medical devices, and telecommunications often standardize on established manufacturer lines to ensure supply continuity and maintain established qualification histories. The CL05C3R3CB5NNNC represents the type of foundational passive component that underpins modern electronics. While small in size and often overlooked in system design discussions, these capacitors are engineered to exacting standards and play an essential role in power integrity, signal integrity, and overall circuit stability across billions of deployed devices worldwide.
