0 euro Resistance

0 euro resistance:
The following functions are available:Jumper. This is both beautiful and easy to install.

② In digital and analog hybrid circuits, it is often necessary to separate the two and single point connection. We can use a 0-euro resistor to connect the two places, instead of directly connecting them together. The advantage of doing so is that the ground lineDivided into two networksIt is much more convenient to deal with copper in a large area. Note that in such cases, the inductor or magnetic beads are sometimes used for connection.

③ DoFuse. That is to say, circuit protection is used. Because the circuit breaking current on the PCB is large, it is difficult to break the circuit in case of short-circuit and over-current faults, which may lead to larger accidents. Because 0-euro resistance and current capacity are relatively weak (in fact, 0-euro resistance also has a certain degree of resistance, but it is only small), the 0-euro resistance will be broken first when the flow is over, thus, the circuit is disconnected to prevent larger accidents. Sometimes the fuse is made with a small resistor with a resistance of a few or a few euros. However, this is not recommended for use, but some vendors will use it to save costs.

④Debugging reservation. You can determine whether to install the tool or other values as needed. Sometimes it is marked with "*", indicating that it is determined by debugging.

⑤Configuration Circuit. This function is similar to patch cord or dial switch, but it is fixed by welding, so that common users can modify the configuration at will. By installing resistance at different positions, you can change the function or set the address of the circuit.
0 euro resistance not only have to sell, but also have different specifications, usually by power, such as 1/8 Watts, 1/4 Watts and so on.

But it is not absolutely non-resistance.
