Abstract

The invention discloses a resistor type winding fuse. The resistor type winding fuse comprises resistor bodies and a support, wherein the resistor bodies are placed in the support, and sealed in the support by coating materials, resistor inside welding pins are welded at the upper end of the support, and reflux welding pins and wave-welding pins are welded at the bottom of the support. According to the resistor type winding fuse and a manufacturing process thereof provided by the invention, the resistor bodies of the resistor type winding fuse are placed in the support to be prevented from being exposed externally by the coating materials; compared with the traditional technology, the resistor type winding fuse disclosed by the invention is small in size, and strong in the chip processing reliability; and more welding ways on a circuit board can be chosen, that is, reflux welding or wave-welding can be chosen or both the reflux welding or wave-welding can be carried out simultaneously to reduce welding intermediate processes, so as to achieve simple flow and reduce cost.
