POLY-FUSE Resettable PTCs 2017 Littelfuse, Inc. Specifications are subject to change without notice. Revised: 03/22/17 Axial Leaded Battery Strap Type > SL Lo Rho Series Description Agency Approvals Features Low Profile Lo Rho (low resistance at normal operating hold current) Installs Directly on battery cell RoHS Compliant, lead- free and halogen-free The new Littelfuse SL LoRho Battery Strap Series PPTC (polymer positive temperature coefficient) is designed with a proprietary conductive polymer material, to provide both over-current and over-temperature protection for rechargeable battery cells. This series features a slim, low profile and low resistance design to install directly on the latest generations of battery cells for a longer battery run time.

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 max = Maximum resistance of device in initial (un-soldered) state. R 1max = Maximum resistance of device at 20C measured one hour after tripping Caution: Operation beyond the specified rating may result in damage and possible arcing and flame.
