Abstract
Provided are a laminated chip composite resistor combining a thermistor and a varistor, and a preparation method thereof. The composite resistor comprises a varistor part, a transition layer part and a thermistor part overlapped sequentially, wherein the varistor part is formed by alternately laminating a ceramic layer of a varistor, a first electrode layer, another ceramic layer of a varistor and a second electrode layer; the thermistor part is formed by alternately laminating a ceramic layer of a thermistor, a third electrode layer, another ceramic layer of a thermistor and a fourth electrode layer; and the transition layer part is located between the thermistor part and the varistor part. Co-firing is employed and the base metal Ni is the main material of inner electrodes, which can reduce costs, simplify the preparation process, and improve the reliability.
