The SCF035-1210R with PTC Resettable Fuses SMD1210 RoHS is a RoHS compliant, single-pole Normal Open (N.O) Surface Mount Resettable Fuses manufactured by SOCAY. The fuse has a rating of 3A, 250VAC and features a tin-plated copper conductivity material for maximum power dissipation and minimize fire risk. Its integrated PTC (Positive Temperature Coefficient) Resettable Fuse automatically cuts off current flow and reset when the temperature of the fuse surpasses its reset temperature. This provides protection against high current over-loads, short circuits, and helps in avoiding damage to sensitive electronic components such as processors, voltage regulators, and more. This part is designed for use in power supplies, lighting fixtures, solar charge controllers, audio systems, lighting control systems and other applications.
