Understanding the Need for 120 Ohm Termination Resistors in CAN Bus Systems
Friends in “Vehicle Technology” should know that the CAN bus requires two 120 Ohm termination resistors at both ends, making the total line resistance 60 Ohms. This is a piece of knowledge that almost everyone knows, but very few can explain clearly. In most cases, we have the experience that adding a 120 Ohm resistor … Read more
