PROBLEM TO BE SOLVED: To provide a surface-mounted PPTC device having a welding plate which is integrally formed or is discretely formed, and then is attached. SOLUTION: A surface mount circuit protecting device 10 includes a laminated PTC resistive element 12, having first and second major surfaces and a thickness between them. A first electrode layer which substantially has the same area as that of the first major surface is made of a first metal material of a type adapted to be soldered to a printed circuit board. A second electrode layer, formed on the second major surface, includes a structure forming or defining a weld plate 18. The device is preferably surface mounted on a printed circuit board assembly and forms a battery protection circuit connected to a battery/cell through battery strap interconnections. One of the battery strap interconnections is micro-spot welded to the welding plate of the device. COPYRIGHT: (C)2006,JPO&NCIPI
