    摘要： A surface mount current fuse of the present invention includes a first base which has a recess and is smaller in width at the other end than at one end in the longitudinal direction, and a second base which has the same shape as the first base. The first base and the second base are combined to form a box-shaped body by joining the lower surface of the second base to the upper surface of the upper surface of the first base in such a manner that one end of the first base and the other end of the second base are in contact with each other. The recess of the first base and the recess of the second base form a space portion in which to dispose an element portion. The borderline between the first base and the second base passes through the center point on a side surface of the body. As a result, the surface mount current fuse has high production efficiency.

    摘要： A chip PTC thermistor comprising a conductive polymer having PTC properties, a first outer electrode, a second outer electrode, one or more inner electrodes sandwiched between the conductive polymer, a first electrode electrically directly coupled with the first outer electrode, and a second electrode. The odd-numbered inner electrode among the one-or-more inner electrodes is directly coupled with the second electrode, while the even-numbered inner electrode, with the first electrode. When total number of the inner electrodes is an odd number the second outer electrode makes direct electrical contact with the first electrode, when it is an even number the second outer electrode makes direct electrical contact with the second electrode. Defining a distance from the odd-numbered inner electrode to the first electrode, or from the even-numbered inner electrode to the second electrode, as “a”, while a distance between the adjacent inner electrodes, or a distance between the inner electrode placed the most adjacent to the first outer electrode, or the second outer electrode, and the first outer electrode, or the second outer electrode, as “t”; the PTC thermistors are constituted so that a ratio a/t is within 3-6. The chip PTC thermistors in accordance with the present invention effectively prevent an overcurrent in large current circuits.
