Abstract: An apparatus for a vehicle includes an electronic device and an ECU. The electronic device includes a conductive housing that comprises a bottom portion, a PCB that comprises a top layer having circuitry, and a ground layer, the PCB located in the housing, a ground component electronically connected to the ECU and the bottom portion, at least one leg that extends through the PCB and fixes the PCB to the bottom portion, and EMC connectors that connect the circuitry to the bottom portion. At a noise frequency, when there is a noise current at a given location of the circuitry, a first noise impedance from the location to the bottom portion through the EMC connectors is less than a second noise impedance from the location to other locations of the circuitry, and less than a third noise impedance from the location to the bottom portion through the leg.
