Bourns MF-PSMF Multifuse® PTC Resettable Fuses

Bourns MF-PSMF Multifuse® PTC Resettable Fuses feature a compact 0805 package with a fast reaction time to short circuit and overcurrent conditions. These fuses have low impedance and can be driven to high impedance by an overcurrent condition or an increase in ambient temperature. Unlike standard single-blow fuses, these fuses can be reset by cycling the power on/off. Bourns MF-PSMF fuses are ideal for USB port protection, HDMI 1.4 source protection, PC motherboards, game console port protection, electronic control modules, mobile phones, and digital cameras.
