Recommendation for series protection resistors on CAN bus?
I never saw series resistors in CAN Networks but the usage of a common mode choke instead (e.g. DLW43SH101XK2#) together with a split termination of 60R + 60R + 4.7nF. (e.g. TJA1057 Datasheet Fig 8 on Page 14). The common mode choke is for EMI compliance at high baudrates. Sometimes I see additionally protection by a Varistor (e.g. B72500E2170S160) to GND on CAN_H and CAN_L.
