WebTerminal resistors are needed in CAN bus systems because CAN communication flows are two-way. The termination at each end absorbs the CAN signal energy, ensuring that this is not reflected from the cable ends. Such reflections would cause interference and potentially damaged signals. WebISO11898. The figure shows the split termination concept, which is helpful when improving the EMC of high speed CAN bus systems Ref. 10. The former single 120 Ω termination resistor is split into two resistors of half value (RT/2) with the center tap connected to ground via the capacitor Cspl. Fig 1.
