Speciﬁcations are subject to change without notice.

Please refer to www.littelfuse.com/series/1812L.html for current information.

Caution: Operation beyond the speciﬁed rating may result in damage and possible arcing and ﬂame.

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 sufﬁx

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 proﬁle devices. For these items the “TH” sufﬁx 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.
