摘要： A multi layer fuse device includes a substrate and an elongated fuse element, having a pair of contact pads formed therewith at opposed longitudinal ends thereof formed on one surface of the substrate. A pair of passivation layers are provided covering the fuse and contact pads. Windows may be opened through both passivation layers above both of the contact pads, and conductive electrode material is electroplated through the windows to contact the contact pads and to extend partially above a top surface of the passivation layers. Exposed electroplated material may be coated with solderable conductive material or a surface mount termination may be provided. Electroplated material may cover a portion of the fuse surface prior to application of the passivation layers and extend to an end of the substrate so that windows are not required.
