Multifuse® PTC Resettable Fuses

Bourns Multifuse® PTC Resettable Fuses are available in polymer or ceramic with surface-mount, through-hole, or strap-mount configurations. The materials used in these fuses allow them to reset after a fault condition has been removed, and the increase in resistance changes exponentially rather than in a linear manner. Resettable overcurrent protection offers reliability and a longer part life. Bourns Multifuse PTCs provide resettable overcurrent protection, extra-low resistance, and are RoHS compliant. These fuses are ideal circuit protection for a variety of industrial and consumer applications, including computer, battery, automotive, and telecommunications.
