Abstract:
1. A chip resistor, comprising: a substrate, having a back face, two side faces, and a main face; a pair of bottom electrodes, disposed on the back face of the substrate and separate from each other, and each bottom electrode having an outer side face; a resistive film, disposed on the main face of the substrate; a pair of main upper electrodes, disposed on the main face of the substrate and separate with each other, and each main upper electrode having an outer side face; a first protective coat, disposed over the resistive film, and covering part of the main upper electrodes; a pair of barrier layers, disposed on the main upper electrodes, and covering part of the first protective coat; a second protective coat, disposed on the first protective coat, and covering part of the barrier layers; a pair of side electrodes, each disposed on the side face of the substrate, the outer side face of the main upper electrode, an outer side face of the barrier layer, and the outer side face of the bottom electrode, for electrically connecting the main upper electrode, the barrier layer, and the bottom electrode; and at least one plated layer, covering the barrier layers, the bottom electrodes, and the side electrodes.
