Abstract
An over-current protection device has a PTC device, first and second electrodes and an insulation layer. The PTC device comprises first and second electrically conductive members and a PTC layer laminated between the first and second electrically conductive members. The first and second electrodes are electrically connected to the first and second electrically conductive members, respectively. The insulation layer is disposed on a surface of the first electrically conductive member. The device is a stack structure extending along a first direction, and comprises at least one hole extending along a second direction substantially perpendicular to the first direction. The value of the covered area of the hole divided by the area of the form factor of the over-current protection device is not less than 2%, and the value of the thickness of the device divided by the number of the PTC devices is less than 0.7 mm.
