POLY-FUSE Resettable PTCs 2017 Littelfuse, Inc. Specifications are subject to change without notice. Revised: 03/22/17 Surface Mount > LoRho Series I hold = Hold current: maximum current device will pass without tripping in 20C still air. I trip = Trip current: minimum current at which the device will trip in 20C 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 (V max ) P d = Power dissipated from device when in the tripped state at 20C still air. R min = Minimum resistance of device in initial (un-soldered) state. R 1max = Maximum resistance of device at 20C measured one hour after tripping or reflow soldering of 260C for 20 sec. Caution: Operation beyond the specified rating may result in damage and possible arcing and flame. Notes: 0805L150SL and 1206L150SL are ideal for overcurrent protection in VBUS of USB 3.0 / USB 2.0 ports. * 1206L380SLTH has I hold 2.82A for at least 15min @ 55C. It is ideal for overcurrent protection in Li-ion / Li-Polymer battery packs of smartphones. ** 1812L350SL Typical Time-To-Trip is 50A at 0.013-0.020 seconds. R1min=0.015ohm (resistance range 0.015-0.025ohm). *** 2920L700SL is ideal for overcurrent protection in Li-ion / Li-Polymer battery packs of tablet PC.
