  • Patent number: 9947443
    Abstract: A chip resistor includes a base member, a resistive element formed on the base member, a first inner electrode held in contact with a first end portion of the resistive element, a second inner electrode held in contact with a second end portion of the resistive element, a first reverse surface electrode reaching a first end portion of the base member, and a second reverse surface electrode reaching a second end portion of the base member. The length of the first and the second reverse surface electrodes is in a range of 2/10 to 3/10 of the length of the base member. Also, the length of the first and the second reverse surface electrodes is greater than the length of the first and the second inner electrodes.

  • Patent number: 8514052
    Abstract: A surface-mounted resistor includes a flat-type base member having a first surface, a second surface, and a lateral surface. Each of the first and second surfaces has a rectangular shape. The surface-mounted resistor also includes a resistance element formed on the first surface; a pair of internal electrodes formed on both ends of the resistance element by being partially superposed with the resistance element; and a pair of external electrodes. Each of the external electrodes has a first bended portion having an L-shape formed by an internal electrode connection portion and a lateral portion, and a second bended portion having an L-shape formed by the lateral portion and a substrate connection portion. The internal electrode and the internal electrode connection portion are fixed to each other through a conductive fixation material, and a position of the base member is biased in a thickness direction toward the first bended portion.

    Abstract: A surface-mounted resistor includes a flat-type base member having a first surface, a second surface, and a lateral surface. Each of the first and second surfaces has a rectangular shape. The surface-mounted resistor also includes a resistance element faulted on the first surface; a pair of internal electrodes formed on both ends of the resistance element by being partially superposed with the resistance element; and a pair of external electrodes.
