I hold = Hold current: maximum current device will pass without tripping in 20°C still air.
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)
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 typ = Typical resistance of device in initial (un-soldered) state.
I max = Maximum fault current device can withstand without damage at rated voltage (V max ) R 1max = Maximum resistance of device at 20°C measured one hour after tripping or re?ow
soldering of 260°C for 20 sec.
Caution: Operation beyond the speci?ed rating may result in damage and possible arcing and ?ame.
1 Effective September 15, 2009 onward, all 1812L PTC products will be manufactured Halogen Free (HF). Existing Non-Halogen Free 1812L PTC products will continue to be
sold until supplies are depleted. Effective January 1, 2010, all 1812L PTC product will be manufactured and sold as Halogen Free by default, and the “HF” part number suf?x
code will be discontinued -- Refer to Part Ordering Number System and Packaging Options sections for additional information.
2 Some older references to these devices may include “ –C “ in the Part Number. The “ –C “ should be omitted when placing new orders for the device.
3 Part numbers ending in “ TH ” refer to new lower pro?le devices. For these items the “ TH ” suf?x 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.
