The SMD1812P200TF/24 with PTC Resettable Fuses 1812 RoHS manufactured by Ruilongyuan is a surface-mount device that combines a 200A polymeric positive temperature coefficient (PPTC) Resettable Fuse with a dual-channel semiconductor switch in an 1812 package. It features low on-resistance, low power dissipation, and wide operating temperature range. The Resettable Fuse provides fast-acting over-current protection including protection against AC/DC short-circuit, overvoltage, over-temperature, and over-power conditions. It is RoHS compliant and compatible with lead-free soldering methods (including Wave, Reflow, and IR Reflow soldering). The device is suitable for use in AC/DC circuits, automotive, consumer electronics, and industrial applications.
