Abstract

The invention relates to a stacking wire wound resistor and a manufacturing method thereof. The stacking wire wound resistor comprises: a ceramic rod having a resistance value, and a basic insulating laser plated thereon, in which the ceramic road is provided with a first end and a second end; a first wire wound resistor, including a first metal wire, having a first wire head and a first wire tail, and wiring surround from the first end to the second end of the ceramic rod, wherein a first insulating layer is plated thereon; and at least a second wire wound resistor, being vertically stacked on the first wire wound resistor and the ceramic rod having a resistor value, and the ceramic rod having a resistor value, the first wire wound resistor and the second wire wound resistor are constituted into a predetermined circuit connection in parallel to raise the ability of anti-surge.

Description

technical field [0001] The present invention relates to a superimposed wire-wound resistor and its manufacturing method, in particular to a vertically superimposed wire-wound resistor capable of greatly improving anti-surge and its manufacturing method. Background technique [0002] In the field of electronics, wire-wound resistors are mainly used in AC and DC circuits such as precision instruments, medical equipment, telecommunication equipment, and electronic equipment as voltage dividers, step-downs, shunts, and load resistors. They can also provide anti-surge functions to Protect the surge generated by instantaneous high voltage without damaging the circuit. When the instantaneous voltage is too high, the general wire-wound resistors still cannot bear it and disconnect, which affects the operation of the circuit. The ceramic rod of the wire-wound resistors has no impedance value. In addition, Japanese Invention Patent No. 3208923 and U.S. Patent No. 9,978,483 (the same ...
