  • Patent number: 8698593
    Abstract: There is provided a chip resistor including a ceramic substrate; a first resistance layer formed on the ceramic substrate and including a first conductive metal and a first glass; and a second resistance layer formed on the first resistance layer, including a second conductive metal and a second glass, and having a smaller content of glass than the first resistance layer, thereby obtaining relatively low resistance and a relatively small temperature coefficient of resistance (TCR).
    Type: Grant
    Filed: April 6, 2012
    Date of Patent: April 15, 2014
    Assignee: Samsung Electro-Mechanics Co., Ltd.
    Inventors: Jang Ho Park, Young Key Kim, Ki Won Suh, Jang Seok Yun, Jin Man Han, Sung Jun Kim

  • Patent number: 8284016
    Abstract: The present invention provides an array type chip resistor including: a substrate having a plurality of grooves formed on both sides thereof at equal spaces; lower electrodes formed on both sides of a bottom surface of the substrate; upper electrodes formed on both sides of a top surface of the substrate; side electrodes electrically connected to the upper and lower electrodes; a resistive element interposed between lower electrodes of the bottom surface of the substrate; a protection layer covered on the resistive element, the protection layer having both sides which cover a part of the lower electrodes and the resistive element; leveling electrodes being in contact with the lower electrodes exposed to outside of the protection layer; and a plating layer formed on the leveling electrodes.

  • Patent number: 8179226
    Abstract: The present invention provides an array type chip resistor including: a substrate formed in a rectangular parallelepiped shape; lower electrodes disposed on both sides of a bottom surface of the substrate at equal spaces; side electrodes extended from some of lower electrodes, formed on outermost edges of both sides of the substrate, in all lower electrodes, to a side surface of the substrate; a resistive element interposed between lower electrodes of the bottom surface of the substrate; a protection layer covered on the resistive element, the protection layer having both sides which cover a part of the lower electrodes and the resistive element; leveling electrodes being in contact with the lower electrodes exposed to outside of the protection layer; and a plating layer formed on the leveling electrodes.
