CL43B103KIFNNWE

The CL43B103KIFNNWE is a multilayer ceramic capacitor (MLCC) manufactured by Samsung, part of their extensive capacitor product line designed for high-reliability industrial and consumer electronics applications. This component falls within the general category of passive electronic components used for energy storage, filtering, and signal coupling in circuit designs. Multilayer ceramic capacitors like this model are fundamental building blocks in modern electronics, found in power supplies, audio equipment, telecommunications infrastructure, automotive systems, and industrial control circuits. The capacitor works by storing electrical charge between conductive plates separated by ceramic dielectric material, allowing it to perform critical functions such as decoupling power supply noise, filtering unwanted frequency components, and coupling AC signals between circuit stages. The part number structure indicates this is a surface-mount component, which is the dominant packaging standard in contemporary electronics manufacturing. Surface-mount MLCCs offer significant advantages over through-hole alternatives, including smaller footprint requirements, reduced manufacturing costs through automated assembly, and reliable soldering compatibility with modern production techniques. The compact size makes these capacitors especially valuable in space-constrained applications where board real estate is premium. Samsung's MLCC products are recognized for consistent quality and reliability across industrial temperature ranges and voltage ratings. Engineers typically specify Samsung capacitors in demanding applications requiring proven performance, stable capacitance values across temperature variations, and low equivalent series resistance (ESR). The manufacturer's quality certifications and long operational history make these components suitable for mission-critical systems where component failure could result in significant downtime or safety concerns. This particular part would be selected by design engineers when their circuit requirements align with its specific electrical characteristics—whether for bulk energy storage in power delivery networks, high-frequency filtering in signal processing circuits, or noise suppression in sensitive analog or digital systems. The choice of a specific capacitor part number depends on several interrelated factors including required capacitance value, voltage rating, size constraints, temperature performance needs, and reliability specifications. Designers working with industrial control systems, power management circuits, or consumer electronics requiring stable, proven components often standardize on Samsung MLCCs due to their consistent availability, documented performance history, and compatibility with established manufacturing processes. This part represents Samsung's commitment to providing dependable passive components for the global electronics industry.
