Bourns Multifuse Polymer PTC Resettable Fuses
Bourns Multifuse Polymer Positive Temperature Coefficient (PPTC) resettable fuses are used in a wide variety of circuit protection applications and in a wide variety of industries. While many materials exhibit a PTC effect when heated, what makes the material used in resettable fuses unique is that the increase in resistance changes exponentially rather than in a linear manner. The fuse will rise exponentially and remain in a tripped state when under fault conditions. This provides continuous circuit protection until the fault is removed.
