I = Hold current: maximum current device will pass without tripping in 20C still air. R = Minimum resistance of device in initial (un-soldered) state. hold min I = Trip current: minimum current at which the device will trip in 20C still air. R = Typical resistance of device in initial (un-soldered) state. trip typ V = Maximum voltage the device can withstand without damage at rated current (I max) R = Maximum resistance of device at 20C measured one hour after tripping. int 1max V = The device regular operation voltage op * Effective February 11, 2010 onward, all 600R PTC products will be manufactured Halogen Free (HF). Existing I = Maximum fault current device can withstand without damage at rated voltage (V ) max max Non-Halogen Free 600R PTC products may continue to be sold, until supplies are depleted.
