RF3041-000 is a quick-acting and resettable PolyFuse from Littelfuse. It is a current-limiting inrush device designed to protect power supplies, charging systems, and other sensitive electronics when subjected to high inrush currents. The device is housed in a surface-mount package, allowing it to be easily integrated into any printed circuit board (PCB) assembly process. Its quick response time helps protect against potential risks, such as component damage and fire, when equipment is powered up. Its resettable nature also allows for longer-term protection, allowing the component to automatically reset itself after over-current or short-circuit events.
