I trip = Trip current: minimum current at which the device will trip in 20°C still air. V max = Maximum voltage device can withstand without damage at rated current (I max) I max = Maximum fault current device can withstand without damage at rated voltage (Vmax) P d = Power dissipated from device when in the tripped state at 20°C still air. R min = Minimum resistance of device in initial (un-soldered) state. R 1max = Maximum resistance of device at 20°C measured one hour after tripping or reflow soldering of 260°C for 20 sec. Caution: Operation beyond the specified rating 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. © 2015 Littelfuse, Inc.
