Generally, it has two pins. It can limit the current through the branch it is connected to. Resistors whose resistance cannot be changed are called fixed resistors. Resistors whose resistance can be changed are called potentiometers or variable resistors. The resistance adjustment operation is more troublesome. Utility Model Content

The threading holes are correspondingly connected to the threaded holes, and one end of the pin is inserted into the threading hole and pressed against the inner electric sheet through a screw matched with the threaded hole. After the iron caps at both ends of the patch resistor core are exposed from the shell, the patch can be used to conduct electricity on the circuit board; or when the pin is installed, the pin can be pressed against the electric sheet by screwing in the screw to prevent it from loosening. The pin can be used to connect electricity around the conductive pillar or inserted into the socket of the circuit board for electricity. A variety of power connection methods, strong versatility.
