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. Notes: 1 Effective September 15, 2009 onward, all 1210L PTC products will be manufactured Halogen Free (HF). Existing Non-Halogen Free 1210L PTC products will continue to be sold until supplies are depleted. Effective January 1, 2010, all 1210L PTC product will be manufactured and sold as Halogen Free by default, and the HF part number sufx code will be discontinued -- Refer to Part Ordering Number System and Packaging Options sections for additional information. 2 Part numbers ending in TH refer to new lower prole devices. For these items the TH sufx must be included in the ordering instructions. Please refer also to the Dimensions and Part Ordering Number System sections of this document for additional information. Orders for the original thicker product (No TH in part number) may be accepted in some instances through October 31, 2009. Please contact Littelfuse for additional information or arrangements. 33 2010 Littelfuse, Inc 1210L Series Specications are subject to change without notice.
