Abstract
A high power resistor device and method for making a high power resistor device. A resistor is formed on a first end of a fired, ceramic chip with multiple internal conductor electrodes, and end terminations are then applied to both ends of the chip. A power resistor device having a high power rating is thus provided having buried conductor electrodes electrically connected to end terminations, where the connection at the first end is through the resistor to form a power resistor structured to dissipate heat efficiently. In an alternative method of the present invention, both ends of the chip may be dipped in resistor paste to form resistors on both ends of the chip. In yet another alternative method of the present invention, a conductor under-layer is formed under the resistor, such as by first dipping the end of the chip in a conductor paste and firing the chip.
