Abstract: A device assembly for surface mount devices includes a matrix of SMD skeletons and a polymeric positive temperature coefficient (PPTC) material disposed over the matrix. The matrix consists of multiple rows, with each SMD skeleton having a pair of terminals and multiple whiskers perpendicular to and between the terminals. The PPTC material connects the terminals to the whiskers.
