Patent ID: 8310334

Claim:
A surface mount resistor, comprising: a resistance body having a first end portion, a second end portion opposite to the first end portion, and a central portion between the first end portion and the second end portion; a first protective layer disposed on the central portion of the resistance body; a first heat-transfer layer disposed on the first end portion of the resistance body and a part of the first protection layer, and having a first heat-transfer portion and a second heat-transfer portion connected to the first heat-transfer portion, wherein the first protective layer is arranged between the first heat-transfer portion and the resistance body, and the second heat-transfer portion is connected to the first end portion of the resistance body; and two electrode layers covering the first end portion and the second end portion of the resistance body, and being electrically connected to the first heat-transfer layer, wherein a central line located between the first and the second end portions and passing through a geometric center of the resistance body is defined, and a part of the central line is covered by the first heat-transfer portion of the first heat-transfer layer.
