Itrip = Trip current: minimum current at which the device will trip in 25℃ still air. Vmax = Maximum voltage device can withstand without damage at rated current (Imax) Imax = Maximum fault current device can withstand without damage at rated voltage (Vmax) Pd typ. = Typical power dissipated from device when in the tripped state at 25℃ still air. Rmin = Minimum resistance of device in initial (un-soldered) state. R1max = Maximum resistance of device at 25℃ measured one hour after tripping or reflow soldering of 260℃ for 20 sec. Caution：Operation beyond the specified ratings may result in damage and possible arcing and flame.  WARNING  Users shall independently assess the suitability of these devices for each of their applications.  Operation of these devices beyond the stated maximum ratings could result in damage to the devices and lead to electrical arcing and/or fire.  These devices are intended to protect against the effects of temporary over-current or over-temperature conditions and are not intended to perform as protective devices where such conditions are expected to be repetitive or prolonged in duration.  Exposure to silicon-based oils, solvents, electrolytes, acids, and similar materials can adversely affect the performance of these PPTC devices.  These devices undergo thermal expansion under fault conditions, and thus shall be provided with adequate space and be protected against mechanical stresses.  Circuits with inductance may generate a voltage (L di/dt) above the rated voltage of the PPTC device.
