CL31B104KCFNNNE by Samsung is a ceramic capacitor commonly used in general-purpose filtering, decoupling, and noise-suppression roles across consumer, industrial, and embedded electronic designs. Components in this category are often selected to stabilize power rails, support signal integrity, and improve overall circuit reliability in compact PCB layouts. For design engineers and sourcing teams, this part is relevant where a dependable multilayer ceramic capacitor solution from a major manufacturer is preferred for volume production or maintenance procurement. Because the exact lifecycle status provided here is unknown, teams should treat long-term supply planning with caution and confirm current manufacturer status before locking it into new designs. RoHS compliance information is not available from the input provided, so engineers should verify compliance, material declarations, and any applicable environmental documentation directly through the official Samsung datasheet, manufacturer portal, or authorized distribution channels before qualification or regulated-market deployment.
