两个120欧姆电阻与一个60欧姆相同。如果电缆长度比较长,那么电阻必须位于电缆的两端。这是为了防止反射。当然,如果没有电缆,它都是一个小板,电阻器的位置并不重要,但你确实需要整个60欧姆电阻。

Two 120 Ohm resistors is the same as one 60 Ohm. If you have relatively long cable, then the resistors must be located on the ends of the cable. This is to prevent reflections. Of course, if there's no cable and it all is on a small board, the position of the resistors doesn't matter, but you do need the overall 60 Ohm resistance.
