Abstract
An activatable thermal fuse includes a first electrical terminal, a second electrical terminal, and an electrically conductive bridge element having a first electric contact with the first electrical terminal and a second electric contact with the second electrical terminal. At least a part of the bridge element is displaceable from a first position in which the first contact is established to a second position in which the first contact is opened, and a thermally sensitive member releases the part when exposed to a predetermined temperature value. An activating element blocks displacement of the part from the first position, in a first position of the activating element, and enables the displacement of the part in a second position of the activating element. A method of manufacturing a printed circuit board, a method of monitoring, and an electronic circuit including the thermal fuse are also provided.
