    Example of noise suppression in the power circuits of devices mounted in vehicles

    The power circuits use a switching system that increases efficiency, but is also a source of problematic noise. Noise suppression measures for the power circuits (DC-DC converter) of devices mounted in vehicles are described below.
    For automotive LANs Suppression of noise in CANs using common mode choke coils

    Introduce noise countermeasure example for CAN line which is used for automotive communication network.
    Examples of actions taken to comply with the CISPR25 standard governing radio emissions (noise emitted) from devices mounted in vehicles

    There are many kinds of problematic noise that are emitted from the devices installed in vehicles.
    The examples of the actions taken to suppress noise described here deal with the noise that is radiated from the USB signal cables.
