Noise suppression technologies/case study introduction (Automotive)

For automotive LANs Suppression of noise in CANs using common mode choke coils (7) Waveform evaluation system

Evaluation system

After passing through the filter, the voltages of the CAN_H and CAN_L lines were measured using the probes.

Differential voltage Vd was measured from the values thus obtained.
(Vd = VCAN_H – VCAN_L)

<Evaluation conditions>

DUT: CAN transceiver(previously made by company A)

Evaluation items: Common mode choke coils

(DLW43SH510XK2, DLW43SH101XK2; DLW32SH510VK2, DLW32SH101VK2)
