The MF-FSMF050X-2 is a Resettable Fuses - PPTC (Polymeric Positive Temperature Coefficient) model manufactured by Bourns. It is designed for low-voltage applications from 6 to 32 volts, and can withstand current up to 40 amps. It features a surface-mountable package with a standoff height of 1.75mm. Its quick-stabilizing fuse characteristics help protect against short-circuits and surges by limiting current spikes, while allowing for constant current flow during normal operation. The fuse also features an off-state resistance of less than one ohm, and a low-temperature coefficient that maintains a stable time-delay at operating temperature.
