I _hold = Hold current: maximum current device will pass without tripping in 23°C still air.
I _trip = Trip current: minimum current at which the device will trip in 23°C still air.
V = Maximum voltage device can withstand without damage at rated current (I )

R _min = Minimum resistance of device in initial (un-soldered) state.
R _1max = Maximum resistance of device at 23°C measured one hour after tripping.
Caution: Operation beyond the specified rating may result in damage and possible arcing
and flame.
* 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.
