Bourns MF-PSML300/12-2 PPTC resettable fuse 3A, 12V, 0805
The Bourns MF-PSML300/12-2 is a very low resistance PPTC resettable fuse (Polymeric Positive Temperature Coefficient) that protects electronic devices from overcurrent and short circuits. In a fault condition the component’s resistance rises rapidly, automatically limiting the current. Once the fault is cleared the fuse returns to its normal state without the need for replacement.
The compact 0805-sized SMD package and low resistance make the component an excellent choice for protecting USB ports, battery-powered devices, mobile electronics, and other space-constrained applications.
