MF-RG1100-AP

PTC Resettable Fuses
PTC (Positive Temperature Co-efficient) Resettable Fuses or PTCR, are devices used to protect electrical circuits from overload and short circuit. They work on the principle of electromechanical resistance, where the resistance increases as the current flowing through it increases beyond a certain level. Unlike traditional fuses, which need to be replaced after they trip, PTCR can be reset easily after the over-current condition is removed. They are also known as polyfuses, polyswitches or self-resettable fuses.MF-RG1100-AP is a PTCR that has been designed for use in a wide range of applications. It has an operating temperature range of -40 to +85°C and a high current rating of up to 1.1A. The device has a low resistance of 12mΩ which makes it suitable for low power applications. This PTCR also features a special quenching system that ensures fast recovery at the end of an overload state.In terms of its working principle, MF-RG1100-AP works as a linear resistor that is triggered and opens when an overload current passes through it. The point at which the overload current is triggered is known as the ‘trip point’. When a high current passes through the fuse and increases beyond the trip point, the fuse changes from a low resistance to a high resistance, which limits the current flow in the circuit. Once the over-current condition is removed and the current passes below the trip point, the fuse reset itself to its normal low resistance state, ready to repeat the same process of protection once more if required.MF-RG1100-AP’s can be applied in various applications such as automotive, consumer electronics, portable device, medical, and industrial. In terms of automotive applications, it is used in the power management circuit, safety systems, and other safety features of cars and trucks. For consumer electronics, it is used to protect circuits from short circuits and overloads. In portable devices, it is used to protect circuits from over-current and over-voltage situations. In medical applications, it is used in smart medical devices, body sensors, monitoring, and imaging systems. Lastly, in industrial applications, it is used to protect motors, machinery, and electronic equipment from over-current conditions.In conclusion, MF-RG1100-AP is a PTCR designed to be used in a wide range of applications. It has a high operating temperature range, a high current rating, and a low resistance. Furthermore, it has a special quenching system that ensures fast recovery. In terms of applications, it can be used in automotive, consumer electronics, portable device, medical, and industrial applications. It is a reliable and cost-effective solution for protecting circuits from overloads, short circuits, and over-current conditions.
