The mSMD125 with PTC Resettable Fuses 1812 RoHS manufactured by TECHFUSE is an ultra-compact, surface mounted, self-resetting fuse designed to protect electronics from overcurrent and short-circuiting. It is RoHS compliant and has a current rating of 125A. The fuse features a PTC reset element that increases the resistance when overloaded, preventing further overcurrent and allowing the device to reset automatically when the current returns to normal. This fuse is an ideal solution for applications such as solar fans, electric vehicles, appliances, power supplies, three-phase inverters, and other types of relatively high-current consumer and industrial electronics.
