Ballast fuses provide overcurrent protection in light ballasts and power inverters. Littelfuse makes two versions of these flat, fast-acting fuses. Our surface mount ballast fuse is designed specifically for soldering onto a printed circuit board. Our axial radial thru hole ballast fuse comes with wire leads attached. Both boast miniature designs and high reliability.
