Abstract
The invention relates to a chip resistor. A method of manufacturing a chip resistor comprises the steps of: (a) applying a conductive paste on an insulating substrate, wherein the conductive paste comprises, (i) 40 to 80 weight percent (wt. %) of a conductive powder; (ii) 1 to 14 wt. % of a glass frit, (iii) 0.01 to 3 wt. % of magnesium oxide (MgO), and (iv) 10 to 55 wt. % of an organic vehicle, wherein the wt. % is based on weight of the conductive paste; (b) firing the applied conductive paste to form the front electrodes.
