CL31B106KOHNNNF

The CL31B106KOHNNNF is a multilayer ceramic capacitor (MLCC) manufactured by Samsung, designed for general-purpose decoupling and filtering applications in electronic circuits. This component belongs to Samsung's established line of ceramic capacitors widely used across industrial, consumer, and automotive electronics. Multilayer ceramic capacitors are fundamental passive components found in virtually every modern electronic device. They serve critical functions including power supply filtering, signal coupling and decoupling, noise suppression, and EMI mitigation. The compact form factor and reliability of ceramic capacitors make them the preferred choice for high-volume manufacturing and space-constrained applications. The CL31B designation indicates this capacitor uses a specific case size format commonly encountered in industrial and commercial electronics. Samsung's CL series represents a mature, well-established product family with proven performance across decades of deployment. These capacitors are manufactured using multilayer ceramic technology, which provides stable capacitance across a wide temperature range and delivers excellent frequency response characteristics essential for modern switching power supplies and digital circuits. Typical applications for this component family include power supply circuits in industrial controllers, telecommunications equipment, server power distribution, automotive engine control modules, LED drivers, and renewable energy inverters. Engineers specify these capacitors in situations requiring reliable filtering of DC bus voltages, smoothing of rectified AC power, and high-frequency noise rejection near switching device switching nodes. The ceramic material composition and construction method provide several advantages that make capacitors like this particularly attractive for engineering specifications. They exhibit low equivalent series resistance (ESR) and equivalent series inductance (ESL), making them effective at higher frequencies where electrolytic capacitors become ineffective. This characteristic is especially valuable in modern switching power supplies operating at frequencies ranging from hundreds of kilohertz to several megahertz. Ceramic capacitors also demonstrate excellent reliability, with very low failure rates when operated within rated parameters, and they maintain consistent performance over extended temperature ranges typical of industrial environments. Unlike electrolytic alternatives, ceramic capacitors contain no liquid electrolyte, eliminating concerns about leakage current, electrolyte drying, or degradation over time. This makes them particularly suitable for applications requiring long operational lifespans without maintenance or replacement. The Samsung CL31B series represents a cost-effective solution for engineers balancing performance requirements against Bill of Materials constraints. Engineers select this specific part number when they require a proven, widely-available ceramic capacitor that meets established performance criteria for filtering and decoupling applications in industrial-grade electronic systems.
