Surface mountable electrical device

摘要

A surface mountable electrical devices includes a PTC resistive element having opposite first and second surfaces and lateral faces interconnecting the first and second surfaces, spaced apart first and third electrode layers formed on the first surface, a second electrode layer formed on the second surface, and a conductive layer. Each two adjacent lateral faces defines a corner that has a terraced face. The conductive layer has a first lateral segment formed on the third electrode layer, a second lateral segment formed on the second electrode layer, and a transverse segment formed on the terraced face of one of the corners and having a terraced cross-section.
