Abstract
A chip resistor includes an insulating substrate, top terminal electrodesformed on top surface of the substrate using silver-based cermet, bottom electrodes, resistive elementthat is situated between the top terminal electrodesand overlaps them partially, an optional internal protective coatingthat covers resistive elementcompletely or partially, an external protective coatingthat covers completely the internal protection coatingand partially covers top terminal electrodes, a plated layer of nickelthat covers face sides of the substrate, topand bottomelectrodes, and overlaps partially external protective coating, finishing plated layerthat covers nickel layer. The overlap of nickel layerand external protective layerpossesses a sealing property because of metallization of the edges of external protective layerprior to the nickel plating process.
