Abstract: A low-capacitance multilayer chip varistor has capacitance lower than 0.5 pF at 1 MHz and has a characteristic of resisting more than thousands of times of 8 KV electrostatic shock, which comprises a ceramic main body, outer electrodes disposed at two ends of the ceramic main body and inner electrodes disposed therein; the ceramic main body comprises inorganic glass of 3˜50 wt % and semi-conductive or conductive particles of 50˜97 wt % with particle size of more than 0.1 ?m, and a layer of inorganic glass film covers the surface of semi-conductive or conductive particles, wherein the inorganic glass film contains semi-conductive or conductive particles of submicron or nanometer which is smaller than 1 micron, and the quantity contained of semi-conductive or conductive particles is less than 20 wt % of that of inorganic glass.
