ABSTRACT:
A surface mountable PTC device includes a PTC layer, first and second electrodes formed on the PTC layer, first and second insulating layers formed respectively on the first and second electrodes, and first and second terminals connected respectively and electrically to the first and second electrodes. Each of the first and second electrodes is formed with a hole. Each of the first and second insulating layers fills the electrode hole in the respective one of the first and second electrodes and is formed with an insulating hole surrounded by the electrode hole. Each of the first and second terminals extends through the insulating hole in the respective one of the first and second insulating layers.
