Electronic part and electronic control unit

An electronic part mounted to a printed board comprising:

• a main body arranged at a position above and separated from a board surface of the printed board, the main body having at least one electronic element and multiple electrodes for the electronic element;
• and
• multiple terminals, each of which is connected at its one end to each of the electrodes and electrically and mechanically connected at its other end to a land formed in the printed board, each of the terminals extending from the main body toward the printed board so as to hold the main body at the position above and separated from the board surface in a condition that each of the terminals is electrically and mechanically connected to the respective electrodes and the respective lands;
• wherein each of the terminals has an electrode-connected portion electrically and mechanically connected to the corresponding electrode, a land-connected portion electrically and mechanically connected to the corresponding land, and an intermediate portion for connecting the electrode-connected portion and the land-connected portion with each other,
• wherein the terminals include at least one fuse terminal,
• wherein the fuse terminal has a first connecting portion at least as a part of the intermediate portion, the first connecting portion extending in a direction parallel to the board surface or in a direction inclined with respect to the board surface by an angle smaller than 90 degrees,
• wherein the fuse terminal further has a cut-off portion formed in the first connecting portion,
• wherein the cut-off portion, which has a width smaller than that of other portions of the fuse terminal, is melted down due to heat generation by excess current, and
• wherein the fuse terminal has tapered portions at both sides of the cut-off portion, so that the cut-off portion is respectively connected to the electrode-connected portion and the land-connected portion via the respective tapered portions.
