Trip current: minimum current at which the device will trip in 25℃ still air. Maximum voltage device can withstand without damage at rated current (Imax). Maximum fault current device can withstand without damage at rated voltage (Vmax). Typical power dissipated from device when in the tripped state at 25℃ still air. Minimum resistance of device in initial (un-soldered) state. 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 prolonged 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.
