R min = Minimum resistance of device in initial (un-soldered) state. I trip = Trip current: minimum current at which the device will trip in 20°C still air. R 1max = Maximum resistance of device at 20°C measured one hour after tripping. V max = Maximum voltage device can withstand without damage at rated current (Imax) Caution: Operation beyond the specified rating may result in damage and possible arcing and flame. I max = Maximum fault current device can withstand without damage at rated voltage (Vmax) Pd = Power dissipated from device when in the tripped state at 20°C still air. * Effective January 1, 2010, all 30R PTC products will be manufactured Halogen Free (HF). Existing Non-Halogen Free 30R PTC products may continue to be sold, until supplies are depleted. © 2015 Littelfuse, Inc. Specifications are subject to change without notice.
