P = Power dissipated from device when in the tripped state at 20C still air. hold d I = Trip current: minimum current at which the device will trip in 20C still air. R = Minimum resistance of device in initial (un-soldered) state. trip min V = Maximum voltage device can withstand without damage at rated current (I max) R = Typical resistance of device in initial (un-soldered) state. max typ I = Maximum fault current device can withstand without damage at rated voltage (V ) R = Maximum resistance of device at 20C measured one hour after tripping or reow max max 1max soldering of 260C for 20 sec. Caution: Operation beyond the specied rating may result in damage and possible arcing and ame. *Note: Some devices in this product series may have C in the Part Number. The C should be omitted when placing orders for the device. 2008 Littelfuse, Inc. Revised: October 24, 2008 1812L Series Specications are subject to change without notice.
