Surface-mounted polymer PCT overcurrent protection element having small package size

A surface-mounted polymer PTC overcurrent protection element having a small package size, comprising:

• a first conductive electrode, a second conductive electrode, a PTC chip located between the first and second conductive electrodes, an insulating layer having a first layer side in contact with the first conductive electrode, a second layer side in contact with a first end electrode and a second end electrode,
• a dividing gap on the first conductive electrode to form first and second conductive areas, at least one conductive member arranged at an edge or at least a corner of the first conductive area for conducting the first conductive area and the second conductive electrode,
• wherein at least one portion in the dividing gap is parallel to the longitudinal direction of the first end electrode and the second end electrode, and wherein the dividing gap is filled with a resin material.
