Chip resistor having low resistance and method of making the same
Abstract:
A resistor, including a resistive element made of a metal plate, has a low resistance resulting from connection terminal electrodes formed on both ends of the lower surface of the resistive element. The object thereof is to achieve weight reduction and lower costs by reducing the height of the resistor. To achieve the above object, the ends of the lower surface of the resistive element are provided with recesses for accommodating the connection terminal electrodes, while at least the intermediate area of the lower surface of the resistive element between the connection terminal electrodes is covered with an insulator. Alternatively, a recess may be formed in the middle of the lower surface of the resistive element for using the ends of the lower surface as a pair of connection terminal electrodes, the recess being internally covered with an insulator.
