Patent ID: 8451084

Claim:
A laminated SMD-type thermistor, comprising: a multi-part conductive module, the multi-part conductive module including a core conductive module including a conductive unit which includes an upper metal foil, a conductive polymer chip with a PTC property, and a lower metal foil, wherein the upper metal foil, the conductive polymer chip and the lower metal foil are laminated in sequence from a top to a bottom of the core conductive module, and a multi-layer insulating layer, the multi-layer insulating layer including an upper insulating layer, a lower insulating layer, a left insulating layer, and a right insulating layer, wherein the upper insulating layer and the lower insulating layer are coated on the upper surface and the lower surface of the core conductive module respectively, the left insulating layer and the right insulating layer are coated on the left side and the right side of the core conductive module respectively; and a left conductive metal layer and a right conductive metal layer being coated on the left part and the right part of the multi-part conductive module respectively, wherein the left conductive metal layer electrically connects with the upper metal foil/the lower metal foil by penetrating a groove of the left insulating layer, and the right conductive metal layer electrically connects with the lower metal foil/the upper metal foil by penetrating a groove of the right insulating layer.
