    334334Common solutions include:
    335335 * Install a ferrite around the power cable
    336   * This typically has not been sufficient enough, but each case will vary
     336  * Typically a large in-line inductor (around 22uH on +VCC input) will provide enough filtering. Note that this inductor has to be sized to handle the amount of current the board is drawing under load. Locate it as close as possible to the board. Note that the inductor will slow the rise/fall time of the input voltage so test with a particular configuration to make sure there are no start-up issues. These inductors can be quite large, especially for high current applications.
     337  * Here would be a suggested example part: [http://www.digikey.com/product-detail/en/abracon-llc/AIAP-02-180K/AIAP-02-180K-ND/3059868]
    337338 * Put a Pi filter inline with the power cable, such example is below:
