Why Is the CAN Bus Termination Resistor 120Ω?
Source | Vehicle Terminal Function of the Termination Resistor The CAN bus termination resistor serves three purposes: 1. Enhance anti-interference capability, allowing high-frequency low-energy signals to dissipate quickly. 2. Ensure the bus quickly enters a dormant state, allowing the energy of parasitic capacitance to dissipate faster; 3. Improve signal quality, placed at both ends of … Read more
